    *       Pursuant to California Rules of Court, rules 8.1105(b) and 8.1110, this opinion is
    certified for publication with the exception of parts II., III., V.E., and V.F.
    SEE CONCURRING OPINION
    Appellant Caltec Ag, Inc. (Caltec) challenges a final administrative decision of the
    California Department of Pesticide Regulation (Department or DPR) that three of
    Caltec’s products were pesticides. Pursuant to Food and Agricultural Code sections
    12993 and 12999.4,1 the Department imposed fines totaling $784,000, finding that the
    products should have been registered as pesticides before being sold in California.
    California’s statutory scheme for the regulation of pesticides defines “pesticide” to
    include (1) any “spray adjuvant,” (2) any mixture of substances intended to be used for
    regulating plant growth, and (3) any substance used to prevent, destroy, repel or mitigate
    any pest. (§ 12753.) Here, the Department determined products named “Greenfeed 27-0-
    0” and “Terra Treat” were spray adjuvants and a product named “Kelpak,” a liquid
    extract from edible seaweed, was intended to be used as a plant growth regulator. Prior
    to the Department’s determinations, the California Department of Food and Agriculture
    (DeptAg) had issued certificates registering the products as specific types of “fertilizing
    materials.” (§ 14533.) Greenfeed 27-0-0 was registered as a “commercial fertilizer”
    (§ 14522), Terra Treat as an “auxiliary soil and plant substance” (§ 14513), and Kelpak
    as an “organic input material” (§ 14550.5). Thus, Caltec contends the products were
    fertilizers and not pesticides.
    As to Greenfeed 27-0-0, we conclude substantial evidence supports the finding
    that this commercial fertilizer is also a spray adjuvant. A Caltec document states
    Greenfeed 27-0-0 is compatible with pesticides other than sulfur, has excellent sticking
    and spreading qualities, and can be used as a carrier for pesticides. The document
    supports a finding that Greenfeed 27-0-0 is a spreading agent intended to be used with
    another pesticide as an aid to the application of the other pesticide. Consequently,
    Greenfeed 27-0-0 satisfies the definition of a spray adjuvant. (§ 12758.)
    1      Subsequent unlabeled statutory references are to the Food and Agricultural Code.
    2.
    Substantial evidence also supports the findings that Terra Treat is a spray
    adjuvant—specifically, a wetting agent that aids the application of pesticides. Terra
    Treat’s label described it as a soil surfactant/penetrant designed to uniformly distribute
    fertilizer, pesticides and water throughout the root zone. Also, a May 2011 technical
    information sheet states Terra Treat significantly increases the effectiveness of certain
    insecticides and herbicides. Based on these and other documents in the record, the
    Department’s finding that Terra Treat is a spray adjuvant and, therefore, a pesticide under
    section 12753 is supported by substantial evidence.
    As to Kelpak, substantial evidence supports the findings that (1) Kelpak is a liquid
    auxin concentrate, (2) naturally occurring auxins in concentrated form are plant growth
    regulators, and (3) Caltec sold Kelpak with the intent that it be used as a plant growth
    regulator. Accordingly, the Department did not commit factual error in determining
    Kelpak is a plant growth regulator and, therefore, a pesticide under section 12753.
    As to the questions of statutory construction involving the relationship between
    the chapter of the Food and Agricultural Code governing pesticides and the chapter
    governing fertilizers, we conclude the DeptAg’s prior registration of Terra Treat as an
    “auxiliary soil and plant substance” (§ 14513) and Kelpak as an “organic input material”
    (§ 14550.5) does not preclude the Department from determining those products were
    pesticides.
    Caltec also has raised claims of procedural and evidentiary error. We conclude
    any procedural error was not prejudicial and Caltec has failed to demonstrate the hearing
    officer’s treatment of the evidence violated an applicable rule of law.
    We therefore affirm the judgment.
    FACTS AND PROCEEDINGS
    Caltec markets and sells a variety of agricultural plant nutrients, crop protectors
    and chemicals. In December 2012, the Department received an email from a licensed
    pest control advisor stating that a product named Microlife was being actively promoted
    3.
    and sold as a nematicide by Caltec even though Microlife was not registered as a
    pesticide. The email attached copies of labels used by the companies selling the
    product.2
    On the morning of May 30, 2013, the Department issued a “NOTICE OF
    INSPECTION” to Caltec for its office in Modesto. The inspector was Saiful Chowdhury,
    who works as an environmental scientist in the Department’s product compliance branch.
    Chowdhury spoke with Caltec’s office manager who informed him no products were
    located at the corporate office in Modesto and customers took possession of the materials
    they ordered at Caltec’s warehouse in Fresno. The office manager provided Chowdhury
    with copies of labels for the products sold and a guide manual for Kelpak. After
    reviewing the documents, Chowdhury issued “PESTICIDE STATUTES VIOLATION
    NOTICE[S]” relating to four products that were not registered as pesticides with the
    Department. The products were Microlife, Greenfeed 27-0-0, Terra Treat, and Kelpak.
    The notices (1) stated the Department’s opinion that the products were pesticides that
    required registration, (2) advised Caltec it was illegal to sell unregistered pesticides in
    California, and (3) noted Caltec had refused to provide sales invoices for the products.
    On June 17, 2013, counsel for Caltec responded to the violation notices by sending
    the Department a letter stating (1) Greenfeed was a fertilizer, (2) Terra Treat was a soil
    penetrant used in irrigation to prevent puddling and to promote lateral movement of water
    in soil, and (3) “Kelpak is a natural plant growth regulator made out of sea weed and is
    used to increase the set and quality of fruits and vegetables.” The letter stated Caltec’s
    position that the products were not pesticides and asserted the products were not intended
    to control or destroy pests. The letter requested the withdrawal of the violation notices.
    2      On appeal, Caltec has not challenged the determination that Microlife was a
    pesticide.
    4.
    The Department did not withdraw the violation notices and continued its attempts
    to obtain sales information for the products. Meanwhile, in November 2013, Chowdhury
    completed an investigation summary using the Department’s preprinted form. The
    investigation summary concluded Microlife, Greenfeed, Terra Treat and Kelpak were
    pesticides. Exhibits to the investigation summary included (1) documents obtained from
    Caltec’s Web site, (2) a September 13, 2012, press release from the United States
    Environmental Protection Agency (EPA), (3) a Kelpak label received from Caltec’s
    owner, (4) documents from the Web site of Kelpak’s manufacturer, and (5) the June 17,
    2013, letter from Caltec’s counsel.
    In December 2013, the Department again requested sales information for the
    products by sending Caltec’s owner a letter. Counsel for Caltec responded in a letter
    dated January 13, 2014, which asserted the products were fertilizers, not pesticides, and
    refused to provide the sales data.
    On May 29, 2014, after failing to obtain sales information through less formal
    means, the Department issued an administrative subpoena duces tecum to Caltec for all
    invoices, bills of lading, receipts and other documents evidencing the sale of Microlife,
    Greenfeed, Terra Treat and Kelpak in California from June 1, 2010, to June 1, 2014. In
    October 2014, Caltec finally produced its sales invoices.
    Notice of Violations
    On January 29, 2015, the Department issued a notice of proposed action to levy
    civil penalties under section 12999.4 (Notice of Proposed Action). The Department
    alleged Caltec violated section 12993 by selling Microlife (17 sales), Greenfeed (133
    sales), Terra Treat (7 sales), and Kelpak (282 sales) in California when those products
    were not registered as pesticides. The Department proposed levying a civil penalty
    totaling $789,000. The Notice of Proposed Action stated Caltec could contest the
    proposed action by requesting a hearing no later than 20 days after its receipt of the
    notice. A form for requesting a hearing was attached.
    5.
    Administrative Proceedings and Decision
    On February 19, 2015, Caltec requested a hearing. The next day—a Friday—the
    Department sent Caltec a notice of hearing stating the hearing would begin on Thursday,
    March 12, 2015, and proposed ongoing hearing dates of the next three business days.
    Caltec’s appellate briefing represents Caltec received the notice of hearing on February
    25, 2015, a Wednesday.3 Additional details about the procedural steps in the
    administrative process leading to the Department’s decision are provided in the
    chronology of events set forth in part II.A.3., post.
    On July 14, 2015, after various procedural steps were completed, including the
    hearing itself, the hearing officer submitted a proposed decision to the Department. The
    proposed decision set forth the statutory definitions of pesticide (§ 12753), spray adjuvant
    (§ 12758), pest (§ 12754.5), and regulating plant growth (§ 12756) and the regulatory
    definition of the phrase “intended to be used” (Cal. Code Regs., tit. 3, § 6145 (Regulation
    6145)). The proposed decision stated (1) Microlife was intended to suppress nematodes,4
    (2) Greenfeed was a spray adjuvant, (3) Terra Treat was a spray adjuvant, and (4) Kelpak
    was a liquid auxin concentrate sold as a plant growth regulator. As a result, the proposed
    decision concluded the four products were pesticides and recommended a penalty totaling
    $939,000 for 438 sales of unregistered pesticides. The unregistered sales had generated
    proceeds of approximately $5,168,000 and, therefore, the proposed fine equaled about
    18.2 percent of the sales revenue.
    On July 17, 2015, the director of the Department, Brian Leahy (Director), issued a
    decision and order adopting the findings in the proposed decision and amending the per
    3      The Department contends the notice was delivered to the offices of Caltec’s
    attorney by certified mail on February 23, 2015, at 3:59 p.m. and cites information
    printed from the United States Postal Service’s tracking Web site.
    4      Microlife’s label described it as a “Nematode Suppressant.”
    6.
    violation penalties, which reduced the total fine to $784,000. The proposed decision as
    modified and adopted by the Director is referred to as the “Decision” in this opinion.
    Administrative Mandamus Proceedings
    In August 2015, Caltec filed a petition for writ of administrative mandamus
    pursuant to Food and Agricultural Code section 12999.4 and Code of Civil Procedure
    section 1094.5. In December 2015, Caltec filed an amended petition.
    After briefing, a hearing on the writ petition, and a hearing on objections to the
    superior court’s statement of decision, the court denied the petition. In September 2016,
    the superior court signed and filed an amended statement of decision and amended
    judgment implementing its decision to deny Caltec’s petition for writ of administrative
    mandamus. Caltec filed a timely notice of appeal challenging the final judgment.
    DISCUSSION
    I.     GENERAL PRINCIPLES
    A.     Standard of Review
    Decisions of the Director are subject to judicial review pursuant to section 1094.5
    of the Code of Civil Procedure, which governs administrative mandamus. (§ 12999.4,
    subd. (c).) When conducting such a review, the court’s inquiry “shall extend to the
    questions [1] whether the respondent has proceeded without, or in excess of, jurisdiction;
    [2] whether there was a fair trial; and [3] whether there was any prejudicial abuse of
    discretion.” (Code Civ. Proc., § 1094.5, subd. (b).) An abuse of discretion can occur
    three different ways: (1) “the [Director] has not proceeded in the manner required by
    law,” (2) the “decision is not supported by the findings,” or (3) “the findings are not
    supported by the evidence.” (Ibid.)
    Generally, one of two different statutory standards govern challenges to the
    sufficiency of the evidence supporting a final administrative decision. The appropriate
    standard is determined by whether the superior court is authorized to exercise its
    7.
    independent judgment on the evidence. (Code Civ. Proc., § 1094.5, subd. (c).) Here,
    neither party contends the superior court was authorized to exercise its independent
    judgment. Therefore, the reviewing court must determine whether the findings are
    “supported by substantial evidence in light of the whole record.” (Ibid.)
    B.     Regulation of Pesticides
    Pesticides are regulated by both the federal government and the State of
    California. In 1947, Congress enacted the Federal Insecticide, Fungicide, and
    Rodenticide Act (FIFRA; 
    7 U.S.C. § 136
     et seq.) to centralize registration and promote
    the accurate labeling of pesticides. (Joiner, Bates v. Dow Agrosciences LLC: The
    Beginning of the End of the “Era of Irresponsibility” (2006) 33 So.U. L.Rev. 361, 363–
    364.) In 1972 Congress transformed FIFRA from a labeling act to a comprehensive
    regulatory statute. (Joiner, supra, at p. 364.) The changes included granting the EPA the
    responsibility of enforcing FIFRA and the authority to determine whether a pesticide
    could be registered and sold in the United States. (Joiner, supra, at pp. 364–365.)
    FIFRA expressly allows states to “regulate the sale or use of any federally
    registered pesticide or device in the State, but only if and to the extent the regulation does
    not permit any sale or use prohibited by [FIFRA].” (7 U.S.C. § 136v(a).) To promote
    uniformity, states shall not impose labeling or packaging requirements different from
    those required by FIFRA. (7 U.S.C. § 136v(b).) In accordance with the provisions of
    FIFRA, the California Legislature has enacted a statutory scheme for the regulation of
    pesticides.
    1.     Registration in California
    A pesticide cannot be sold in California unless the product’s label is registered
    with the Department.5 (§ 12993.)
    5     The Department (i.e., DPR) is one of six agencies operating under the California
    Environmental Protection Agency. (§ 11451.) The California Environmental Protection
    Agency and the DPR were created in 1991 pursuant to the Governor’s Reorganization
    8.
    The purposes of the pesticide registration requirements are to (1) provide for the
    proper, safe, and efficient use of pesticides essential for (a) production of food and fiber
    and (b) protection of the public health and safety; (2) protect the environment by
    regulating or ensuring proper stewardship of pesticides; (3) assure safe working
    conditions for agricultural and pest control workers; (4) assure users that pesticides are
    properly labeled and are appropriate for the use designated by the label; and (5) assure
    users that information on pesticidal use of the product disseminated by state or local
    government is consistent with the uses for which the product is registered. (§ 11501.)
    Before a pesticide can be registered in California, it must first be registered by the
    EPA. (Pesticide Action Network North America v. Department of Pesticide Regulation
    (2017) 
    16 Cal.App.5th 224
    , 232–233.) Compliance with FIFRA and its registration
    requirement has been described as “extremely expensive and time consuming.” (Hansen,
    Agricultural Nonpoint Source Pollution: The Need for an American Farm Policy Based
    on an Integrated Systems Approach Recoupled to Ecological Stewardship (1994) 15
    Hamline J. Pub. L & Pol’y 303, 320.)6 After the EPA has registered a pesticide, it is
    eligible for the Department’s review. (Pesticide Action Network, supra, at p. 233.) The
    Department is charged with thoroughly evaluating the pesticide to ensure that, when used
    Plan. (See Fernandez v. California Dept. of Pesticide Regulation (2008) 
    164 Cal.App.4th 1214
    , 1222.) The DeptAg previously administered California’s pesticide
    regulatory program, but the Governor’s Reorganization Plan transferred the responsibility
    for that program to the DPR. (Ibid.; § 11454.) The DPR and the DeptAg are separate
    agencies and do not share a common parent organization, a fact that has some relevance
    in determining the effect on the DPR of the DeptAg’s decision to register a product as a
    fertilizing material.
    6       “To register a pesticide, [EPA] requires the registration applicant to submit a large
    number of studies concerning the chemistry and toxicology of the pesticide, the potential
    risks it may pose to worker safety and public health, the effects it may have on the
    environment, fish, wildlife and non-target insects, and other studies that bear on the
    pesticides safety and effectiveness.” (Sen. Rules Com., Off. of Sen. Floor Analyses, 3d
    reading analysis of Assem. Bill No. 124, as amended Jun. 11, 1996, p. 2.)
    9.
    in conformance with its labeling, it is effective and will not harm human health or the
    environment. (Ibid.; § 12824.)
    To summarize, the federal pesticide regulatory program and the state program
    require sequential registration of a product the Department has decided is a “pesticide.”
    This registration process is slow and expensive.
    2.      Statutory Definitions
    California’s definition of “pesticide” includes (1) any “spray adjuvant” and (2) any
    substance or mixture “intended to be used for [(a)] defoliating plants, [(b)] regulating
    plant growth, or [(c)] for preventing, destroying, repelling, or mitigating any pest …
    which may infest or be detrimental to vegetation, man, animals, or households, or be
    present in any agricultural or nonagricultural environment whatsoever.” (§ 12753.) In
    comparison, FIFRA defines “pesticide” to mean “(1) any substance or mixture of
    substances intended for preventing, destroying, repelling, or mitigating any pest, (2) any
    substance or mixture of substances intended for use as a plant regulator, defoliant, or
    desiccant, and (3) any nitrogen stabilizer,” subject to certain exceptions that are not
    relevant here. (
    7 U.S.C. § 136
    (u).) Thus, the federal definition does not include “spray
    adjuvants” and California’s definition does not include nitrogen stabilizers.
    For purposes of this appeal, two significant components of the definition of
    “pesticide” are (1) the term “spray adjuvant” and (2) the phrase “regulating plant
    growth.” “‘Spray adjuvant’ means any wetting agent, spreading agent, deposit builder,
    adhesive, emulsifying agent, deflocculating agent, water modifier, or similar agent, with
    or without toxic properties of its own, which is intended to be used with another pesticide
    as an aid to the application or effect of the other pesticide, and sold in a package that is
    separate from that of the pesticide other than a spray adjuvant with which it is to be
    used.” (§ 12758.)
    10.
    “‘Regulating plant growth’ [generally] means the use of any substance or mixture
    of substances intended, through physiological action, for accelerating or retarding the rate
    of growth or rate of maturation, or for otherwise altering the behavior of plants or the
    produce thereof.” (§ 12756.) The statute also sets forth two exceptions to this general
    rule. First, the phrase “shall not include the use of substances to the extent that they are
    intended as plant nutrients, trace elements, nutritional chemicals, plant inoculants, and
    soil amendments.” (Ibid.) Second, “‘regulating plant growth’ shall not be required to
    include at all the use of any of such of those nutriment mixtures or soil amendments as
    [1] are commonly known as vitamin-hormone horticultural products, intended for
    improvement, maintenance, survival, health, and propagation of plants and [2] are not for
    pest destruction and [3] are nontoxic, nonpoisonous in the undiluted packaged
    concentration.”
    The phrase “intended to be used” is not defined by the Food and Agricultural
    Code, but is defined in the regulations implementing the pesticide regulatory program.
    (Regulation 6145.) The definition can be satisfied in three different ways:
    “(a) A person who distributes or sells the substance claims, states, or
    implies, by labeling or otherwise, that: [¶] (1) the substance, either by itself
    or in combination with any other substance, can or should be used as a
    pesticide; or [¶] (2) the substance consists of or contains an active
    ingredient and can be used to manufacture a pesticide; or
    “(b) A person who distributes or sells the substance has actual or
    constructive knowledge that the substance will be used, or is intended by
    the user to be used, as a pesticide; or
    “(c) The substance consists of or contains one or more active ingredients
    and has no significant commercially valuable use as distributed or sold
    other than: [¶] (1) use as a pesticide, by itself or in combination with any
    other substance; or [¶] (2) use in the manufacture of a pesticide.”
    (Regulation 6145.)
    The first two definitions are based on intent. The third definition is based on the
    ingredients and does not involve the intent of the seller or the intent to the user.
    11.
    3.      Interpreting Regulation 6145
    The parties disagree as to the proper interpretation of subdivision (c) of Regulation
    6145. Caltec contends the phrase “has no significant commercially valuable use” refers
    to the “substance” and not to “one or more active ingredients.” (Regulation 6145, subd.
    (c).) On appeal, the Department contends the third definition of “intended to be used”
    (Regulation 6145, subd. (c)) allows for the intended use of a substance to be
    demonstrated by the presence of “active ingredients” and, so long as an active
    ingredient’s only significant commercially valuable use is as a pesticide, the actions or
    mental state of the distributor or seller are irrelevant.7
    We conclude the words and grammar of subdivision (c) of Regulation 6145 are
    not ambiguous on the question of whether the phrase “has no significant commercially
    valuable use” refers to the “substance” or, alternatively, refers to “one or more active
    ingredients.” The phrase refers to the “substance,” that is the product being sold or
    distributed. Accordingly, to establish a product is a pesticide under the ingredients-based
    definition in subdivision (c) of Regulation 6145, the Department must prove the
    “substance [1] consists of or contains one or more active ingredients and [2] has no
    significant commercially valuable use as distributed or sold other than” use as a pesticide.
    The use of the conjunction “and” clearly establishes that the substance must satisfy two
    elements. (In re C.H. (2011) 
    53 Cal.4th 94
    , 101 [ordinary and usual usage of statutory
    7       Neither the Director nor the hearing officer expressly interpreted subdivision (c) of
    Regulation 6145 to mean the phrase “has no significant commercially valuable use”
    refers to “one or more active ingredients” and not to the “substance.” Generally, when an
    agency’s interpretation is carefully considered by senior agency officials, it is entitled to
    correspondingly greater weight. (Allende v. Department of California Highway Patrol
    (2011) 
    201 Cal.App.4th 1006
    , 1018.) In contrast, an argument advanced by the agency’s
    litigating counsel is not regarded as an agency interpretation and, thus, is given less
    weight. (Ames v. Merrill Lynch, Pierce, Fenner & Smith, Inc. (2d Cir. 1977) 
    567 F.2d 1174
    , 1177, fn. 3; see 2B Singer & Singer, Statutes and Statutory Construction (7th ed.
    2012) § 49:4, p. 85 [“arguments of an agency’s counsel do not have the probative force of
    an official agency interpretation”].)
    12.
    term “and” is as a conjunctive, meaning an additional thing, also, or plus].) If the
    reference to the absence of commercial value had been intended to modify the phrase
    “one or more active ingredients,” the words “and has” would have been replaced with
    “that have” or “having.” (See Surfrider Foundation v. California Regional Water Quality
    Control Bd. (2012) 
    211 Cal.App.4th 557
    , 576 [courts must interpret statutes consistent
    with the meaning derived from its grammatical structure].)
    The interpretation of subdivision (c) of Regulation 6145 advocated by counsel for
    the Department on appeal cannot be adopted by this court because it is contrary to the
    unambiguous language of the regulation. Thus, that interpretation, in effect, rewrites the
    regulation. To be valid, such a rewriting (i.e., amendment) of the regulation must be
    adopted in substantial compliance with the procedures of the Administrative Procedures
    Act (Gov. Code, § 11340 et seq.). (See Patterson Flying Service v. Department of
    Pesticide Regulation (2008) 
    161 Cal.App.4th 411
    , 429 [“underground regulation” is not
    adopted in compliance with Administrative Procedures Act and, thus, is invalid].)
    Based on the foregoing interpretation, the critical facet of the regulatory definition
    of “intended to be used” is set forth in subdivision (a)(1) of Regulation 6145. That
    definition is satisfied when the company selling or distributing the substance claims,
    states, or implies that the substance can or should be used as a pesticide. Under this
    definition, a company must be careful in marketing a product because claims about its
    capabilities, even if inaccurate, could cause that product to be subject to the pesticide
    regulatory program.
    C.     Auxins and Cytokinins
    As part of his investigation, Chowdhury printed a page from a Web site at
    http://www.kelpak.com/activity/how_it_works.html on June 10, 2013. The page
    describes auxins and cytokinins as follows:
    13.
    “Auxins are natural plant hormones produced in a plant’s shoot tips
    and translocate downwards. One of its effects is to signal a plant to
    increase its root growth.
    “Cytokinins are natural plant hormones produced in root tips and
    translocated upwards. One of its effects is to signal a plant to produce more
    and larger foliage.”
    The subject of plant growth regulators is addressed in part II of chapter 15 of
    Anderson & Simon, Defending Pesticides in Litigation (2018) (Defending Pesticides).
    Section 15:34 of Defending Pesticides states that “[i]n 1934, auxins were found to
    enhance root formation in cuttings.” Section 15:35 of Defending Pesticides states:
    “Auxins are compounds that induce elongation in shoot cells. Some occur naturally,
    whereas others are manufactured. Auxin precursors are materials that are metabolized to
    auxins in plants.” It also states the mechanism of action is not completely understood,
    but with the addition of auxin the individual cells become larger by a loosening of the cell
    wall, which is followed by increased water uptake and expansion of the cell wall. Auxins
    include the herbicide 2,4-D.8
    Section 15:37 of Defending Pesticides describes cytokinins as “naturally occurring
    or manufactured compounds that induce cell division in plants.” It also states cytokinins
    were discovered in 1955 and have two notable effects in plants—that is, “the induction of
    cell division and the regulation of differentiation in removed plant parts.” Section 15:34
    of Defending Pesticides states that six classes of plant growth regulators are recognized
    by the American Society for Horticultural Science, including auxins, gibberellins,
    cytokinins and ethylene generators.
    8      Section 14031 uses “2,4-D” to mean “any form of 2,4-dichlorophenoxyacetic
    acid.” In 1949, the Legislature made 2,4-D a restricted material. (People ex rel.

    36 Cal.3d 476
    , 481; see Cal. Code Regs., tit.
    3, § 6400, subd. (e) [2,4-D included in pesticides designated restricted materials].)

    II.    ADMINSTRATIVE ADJUDICATION BILL OF RIGHTS*
    A.     Background
    1.     Statutory Provision
    The Administrative Adjudication Bill of Rights (Gov. Code, §§ 11425.10–
    11425.60) was enacted in 1995 (Stats. 1995, ch. 938, § 21) as part of a major revision of
    California’s Administrative Procedure Act. (See California Youth Authority v. State
    Personnel Bd. (2002) 
    104 Cal.App.4th 575
    , 589.) Here, Caltec contends the Department
    violated obligations set forth in Government Code section 11425.10, subdivision (a)(2).
    That provision states:
    “(a) The governing procedure by which an agency conducts an adjudicative
    proceeding is subject to all of the following requirements: [¶] … [¶] (2)
    The agency shall make available to the person to which the agency action is
    directed a copy of the governing procedure, including a statement whether
    Chapter 5 (commencing with Section 11500) is applicable to the
    proceeding.” (Gov. Code, § 11425.10.)
    Caltec contends this provision imposes a mandatory obligation on the Department
    and the obligation has no exceptions. We note that the relevant text does not contain a
    timing element that identifies when the agency must make the copy available and does
    not define the term “available.”9 The Law Revision Commission Comment to
    Government Code section 11425.10 addresses availability by stating:
    “Subdivision (a)(2) requires only that the agency ‘make available’ a copy of
    the applicable hearing procedure. This requirement is subject to a rule of
    reasonableness in the circumstances and does not necessarily require the
    agency routinely to provide a copy to a person each time agency action is
    directed to the person. The requirement may be satisfied, for example, by
    the agency’s offer to provide a copy on request.” (Cal. Law Revision Com.
    *      See footnote, ante, page 1.
    9     In a case involving contractual language, the First District stated: “The phrase ‘to
    make available’ means to make ‘accessible or attainable, ready or handy’ according to
    Webster’s Dictionary.” (De Kay v. De Kay Pneumatic Tools (1955) 
    131 Cal.App.2d 625
    ,
    633.)

    390.)
    2.     Caltec’s Contentions
    Caltec asserts that the Notice of Proposed Action and the subsequent notice of
    hearing did not provide any statement or explanation of the nature or scope of the
    administrative proceedings or the processes and procedures that governed them. Caltec
    further asserts that “these procedures were explained in DPR’s administrative proceeding
    procedures handout, which [the Department] maliciously and prejudicially failed to
    timely furnish to Caltec (including when they were explicitly requested).”
    3.     Chronology of Events
    January 29, 2015: The Department mailed Caltec the Notice of Proposed Action
    alleging Caltec had violated section 12993 by selling pesticides in California without first
    registering them. The notice stated that if Caltec wished to contest the proposed action it
    was required to request a hearing within 20 days of receiving the notice.
    February 19, 2015: Caltec requested a hearing.
    February 20, 2015: The Department sent Caltec a notice stating the hearing
    would begin on Thursday, March 12, 2015, and proposed ongoing hearing dates of the
    next three business days. The notice of hearing stated the Department would provide
    Caltec with a copy of the evidentiary documents and list of proposed witnesses by email
    and an overnight courier no later than March 2, 2015. The notice did not mention the
    governing procedures that would be followed at the hearing or the existence of a brochure
    describing those procedures.
    February 27, 2015: The Department emailed Caltec a copy of a request for
    judicial notice.10 The email listed nine witnesses and stated Caltec should receive a hard
    10      The reference to “judicial” notice is a misnomer because the proceeding is not
    conducted before a judge. Government Code section 11425.50, subdivision (c), which is
    part of the Administrative Adjudication Bill of Rights provides that the facts stated in the
    written decision must be based exclusively “on the evidence of record in the proceeding
    16.
    and electronic copy of the hearing exhibits on Monday, March 2, 2015. The email also
    stated the hearing exhibits “are also available for your review in our office.”
    March 6, 2015: Caltec sent a letter to the Director requesting the hearing be
    continued for at least two months. The letter also stated: “Please provide information
    relevant to DPR’s hearing processes and procedures when responding to this request, so
    Caltec may properly prepare for the continued hearing.” Later that Friday, counsel
    representing the Department sent counsel for Caltec an email stating the “request for a
    continuation of this matter is denied. The hearing will proceed.” The email did not
    respond to the request for information about applicable procedures.
    March 10, 2015: The hearing officer sent an email to counsel for Caltec and the
    Department stating Caltec’s request for a continuance was denied “with the caveat that
    March 12, 2015 will be a prehearing conference where we will sort through evidentiary
    and procedural issues related to the hearing.”
    March 11, 2015: Counsel representing the Department in the administrative
    proceeding sent an email to counsel for Caltec stating: “Please see the attached.” The
    email’s subject line described the attachment as follows: “Handout—Preparing for an
    Administrative Hearing.” This email and attachment responded to Caltec’s March 6,
    2015, request for information about the procedures applicable to the hearing.
    March 12, 2015: The hearing officer met with counsel. The Department
    characterizes the meeting as a prehearing conference. In contrast, Caltec describes it as
    the commencement of the administrative hearing. At the meeting, counsel for the
    Department described the 13 exhibits she intended to submit. Later during the meeting,
    counsel for Caltec stated that she had “just received the voluminous document production
    from DPR a mere seven business days ago.”
    and on matters officially noticed in the proceeding.” (Italics added.) Thus, this provision
    suggests such a request in an administrative proceeding should be called a request for
    official notice, rather than judicial notice.
    17.
    April 1, 2015: Administrative hearing.
    April 3, 2015: Last day of administrative hearing.
    In July 2015, after receiving the posthearing briefing and other submissions, the
    hearing officer issued his proposed decision. A few days later, the Director entered his
    decision and order.
    To summarize, Caltec requested a hearing on February 19, 2015, and the notice of
    hearing sent the next day did not inform Caltec about the governing procedures. After
    Caltec requested such information on March 6, 2015, the Department emailed a copy of
    its brochure on March 11, 2015, the day before counsel first met with the hearing officer.
    The administrative hearing commenced on April 1, 2015.
    B.     Analysis
    1.      Violation Assumed
    Subdivision (a) of Government Code section 11425.10 sets forth requirements for
    an “adjudicative proceeding” conducted by an agency. At a minimum, the adjudicative
    nature of the Department’s administrative proceeding was established when Caltec
    requested a hearing. The Department has offered no explanation for why its brochure
    titled “Preparing for an Administrative Hearing” was not included with the notice of
    hearing or, alternatively, why the notice of hearing did not inform Caltec a copy of the
    brochure was available on request. The sentence immediately following the brochure’s
    title states: “You have requested an opportunity to be heard at an administrative hearing
    regarding alleged violations pertaining to unlawful pesticide sales.” In light of how the
    brochure is drafted, a common sense approach (i.e., one reasonable under the
    circumstances) would be to include the brochure with the notice of hearing or at least
    state a brochure about procedures exists and is available on request.
    In this appeal, we assume, without deciding, the Department violated Government
    Code section 11425.10, subdivision (a)(2) and the violation constituted an abuse of
    18.
    discretion for purposes of Code of Civil Procedure section 1094.5, subdivision (b).
    Specifically, we assume a copy of the brochure should have been included with the
    February 20, 2015, notice of hearing or, alternatively, the notice should have informed
    Caltec of the brochure’s existence and that copy would be provided upon request.
    2.     Prejudice
    Next, we consider whether the assumed abuse of discretion was “prejudicial”
    within the meaning of subdivision (b) of section 1094.5 of the Code of Civil Procedure.
    Caltec has addressed the question of prejudice by arguing how the delay in its receipt of
    the brochure affected its ability to prepare a defense.
    Caltec contends it was unable to utilize many of the prehearing procedural
    entitlements described in the brochure, including (1) “calling DPR to make an
    appointment to view DPR’s evidence” and (2) “requesting to schedule a pre-hearing
    conference with DPR before a hearing was set to commence.” Caltec argues that because
    of the belated transmission of the brochure, “Caltec was prevented from adequately
    preparing for the administrative proceedings before DPR, as it was completely unaware
    of the DPR-specific processes, procedures and rules that applied before, during and after
    the administrative hearing.”
    First, we consider Caltec’s claim that it was prejudiced because it was prevented
    from calling the Department and making an appointment to review the evidence.
    Counsel for Caltec has represented to this court that Caltec received the notice of hearing
    on February 25, 2015. If the brochure had been included with the notice of hearing, the
    earliest Caltec could have scheduled an appointment to review documents would have
    been Thursday, February 26, 2015. Based on the statement of counsel for Caltec, it
    appears she received the Department’s proposed exhibits on Tuesday, March 3, 2015.
    Thus, the failure to include the brochure with the notice of hearing might have delayed
    Caltec’s review of the documents by up to five days. We conclude the five-day delay
    19.
    was not prejudicial to Caltec in the presentation of its defense, which occurred on April 1,
    2015. The amount of time that passed between Caltec’s March 3, 2015, receipt of the
    Department’s exhibits and the presentation of its defense before the hearing officer was
    29 days and Caltec has not shown how an additional five days would have altered its
    presentation of evidence or arguments. Therefore, we conclude Caltec was not
    prejudiced by the delay in being told it could call the Department and making an
    appointment to see the evidence.
    Second, we consider Caltec’s prejudice claim based on its inability to utilize the
    prehearing procedure of “requesting to schedule a pre-hearing conference with DPR
    before a hearing was set to commence.” We reject this argument because Caltec has not
    shown how such a meeting, which would have been held outside the presence of the
    hearing officer, would have affected the proceedings. Moreover, the hearing officer’s
    decision to conduct a conference with counsel on March 12, 2015, and continue the
    matter until April 1, 2015, provided Caltec with an effective substitute for any prehearing
    meeting to confer outside the presence of the hearing officer and prevented any prejudice
    resulting from the delay in informing Caltec of its ability to request such a conference.
    In summary, we conclude Caltec has not demonstrated it was prejudiced by the
    delay (February 25, 2015, until March 11, 2015) in its actual receipt of a copy of the
    brochure describing the governing procedures. Accordingly, the superior court properly
    refused to grant the writ of administrative mandamus based on a violation of Government
    Code section 11425.10, subdivision (a)(2).
    20.
    III.   GREENFEED*
    A.     Background
    1.      Administrative Decision
    The Decision contains a factual background section that includes a paragraph
    addressing Greenfeed 27-0-0 (Greenfeed). The paragraph stated:
    “The Greenfeed label that Caltec gave to Mr. Chowdhury provided that it
    should be diluted with water and blended with pesticides and nutrients only
    at the time of application. Mr. Chowdhury confirmed that blending with
    pesticides confirmed that Greenfeed was an adjuvant. Also the Caltec web
    site claimed that Greenfeed would ‘increase blossom set’ and,
    consequently, was a plant growth regulator. (DPR Exh. 1 at 14, 17, 43-
    57.)”
    The legal framework section of the Decision included the statutory definition of
    “spray adjuvant” (§ 12758) and the regulatory definition of “intended to be used”
    (Regulation 6145). The Decision stated the phrase “intended to be used” applied “to
    situations where the product ‘contains one or more active ingredients and has no
    significant commercially valuable use’ other than as a pesticide.” Based on invoices for
    133 sales of Greenfeed, the Department fined Caltec a total of $133,000.
    Part E of the analysis section of the Decision addressed whether Greenfeed was a
    pesticide. The Decision stated the designations as a fertilizer and a pesticide were not
    mutually exclusive and “Greenfeed could be both.” It also stated: “And, regardless of
    whether it is a fertilizer, as a spray adjuvant, it is definitely a pesticide.” The discussion
    supporting the conclusion that Greenfeed was a spray adjuvant stated:
    “The [133 Caltec] invoices do not describe Greenfeed as a ‘spray adjuvant’
    for pesticides. Most of the invoices involve the sale of Greenfeed only with
    ‘27/75-0-0’ as the description. Five of the invoices also included sales of
    pesticides. (DPR Exh. 7 at 557-561.) None included the sale of other
    nutrients.
    *      See footnote, ante, page 1.
    21.
    “As outlined above, to support its assertion that Greenfeed is a ‘spray
    adjuvant,’ DPR provides statements f[ro]m the Caltec Web site and from
    the Greenfeed label that it should be diluted and combined with pesticides.
    (DPR Exh. 1 at 17.) Caltec stated that Greenfeed is ‘Compatible with
    pesticides other than sulfur [and has] excellent sticking and spreading
    qualities [and can be used] as a carrier for most pesticides.’ DPR witness
    Saiful Chowd[hu]ry, obtained these labels from Caltec on May 30, 2013.
    Mr. Chowd[hu]ry’s expert testimony at the administrative hearing was
    relevant and reliable.”
    Part E of the Decision’s analysis section also addresses a factual dispute about
    whether copies of Greenfeed’s label were provided to the general public or Caltec’s
    distributor clients. The decision states Chowdhury was provided a copy of Greenfeed’s
    label on May 30, 2013, and then states: “Furthermore, even if Caltec did not provide
    copies of the label [to the public or its distributors], Caltec does not deny that Greenfeed
    was sold as a spray adjuvant; that is its primary purpose.”
    2.     Greenfeed’s Certification and Label
    The March 2015 declaration of Caltec’s president and owner is part of the
    administrative record. The declaration states “Caltec has held a Certificate of
    Registration for Fertilizing Materials” for Greenfeed from the DeptAg since
    approximately 1995. Attached to the declaration was a copy of the DeptAg’s certificate,
    which listed Greenfeed under the heading “Commercial Fertilizer.”
    The label for Greenfeed included in the administrative record states “A FOLIAR
    SLOW RELEASE NITROGEN” with a guaranteed analysis of 27 percent total nitrogen.
    Urea nitrogen constitutes 7.56 percent of Greenfeed, and slowly available water soluble
    nitrogen from polymethylene urea, monomethylol urea, and methylene diurea constitutes
    19.44 percent of Greenfeed. These two percentages, when added together, equal the total
    nitrogen of 27 percent referred to on the label.
    The Decision refers to blending instructions set forth in Greenfeed’s label. The
    instructions state: “Dilute with water and blend with other nutrients and pesticides only
    22.
    at the time of application and in the amounts required.” The instructions also direct the
    user to “See Caltec Application Guide.”
    3.     Caltec’s Greenfeed Documents
    The administrative record contains documents related to Greenfeed and printed on
    May 30, 2013, from a Web site maintained by Caltec. One document describes the foliar
    benefits of Greenfeed. Other documents are application guides, including a general
    application guide for all crops and other guides for specific crops or plants, such as
    almonds, cotton, grass seed, lawn care, pears, potatoes, tomatoes and young trees.
    The document describing the foliar benefits of Greenfeed consists of 14 bullet
    points. The Department highlighted the following three bullet points to support its
    contention Greenfeed was a spray adjuvant: “COMPATIBLE WITH PESTICIDES
    OTHER THAN SULFUR”; “EXCELLENT STICKING AND SPREADING
    QUALITIES”; and “USE AS CARRIER FOR MOST PESTICIDES.”
    Other bullet points address Greenfeed’s use as a fertilizer. For instance, the first
    two bullet points state: “SLOW RELEASE IN PLANT PROVIDES SIGNIFICANTLY
    IMPROVED NITROGEN BALANCE OVER EXTENDED PERIOD OF TIME” and
    “NO ‘QUICK’ FLUSH OF GROWTH, GRADUAL GREENING.” Other points state
    Greenfeed is economical when the efficiencies of foliar versus soil fertilizer are
    considered and it can be used undiluted on some crops.
    The application guide for tomatoes includes the following statement:
    “GREENFEED, a liquid controlled release urea based nutrient, when applied at bloom,
    triggers flower initiation and set. This is a result of the addition of NH3- NH4+ to the plant
    which activate polyamines and triggers floral fluorescence in the plant. [¶] The second
    application maintains the nitrogen level necessary to sustain set and helps to produce a
    canopy which reduces sunburn and/or heat stress.” Another application guide states:
    “Foliar application of GREENFEED foliarly provides a 4 to 6 (and sometimes more) to 1
    23.
    efficiency factor, compared to soil applied nitrogen. [¶] Foliar Nitrogen can be applied
    for efficient results WHEN and WHERE the plant needs it as opposed to soil applications
    of Nitrogen which require days to covert in the soil to a usable form.” An almond
    recommendation guide states that “during the bloom period, a mature almond tree will
    require 2-3 pounds of nitrogen per acre per day. Greenfeed can safely supply this
    Nitrogen in the form of NH4+ at a very low cost per acre.”
    A Caltec product guide for 2008 includes “Greenfeed 27/75-0-0” at the top of a
    list of proprietary slow release nitrogen products. This product guide was obtained by
    Chowdhury from the Caltec Agri Marketing Services Web site located at
    .
    B.     Greenfeed as a Commercial Fertilizer
    1.     Statutory Definitions and Regulations
    “Commercial fertilizer” is defined by section 14522 as “any substance which
    contains 5 percent or more of nitrogen (N), available phosphoric acid (P2O5), or soluble
    potash (K2O), singly or collectively, which is distributed in this state for promoting or
    stimulating plant growth.” Nitrogen, available phosphoric acid, and soluble potash are
    designated by section 14556 as the three “[p]rimary plant nutrient[s].” The term “[l]abel”
    encompasses the written, printed or graphic material on the container and “a statement,
    including guaranteed analysis, accompanying fertilizing material.” (§ 14540, italics
    added.) “‘Guaranteed analysis’ means the minimum percentage of primary or secondary
    plant nutrients or micronutrients, or both, claimed.” (§ 14536.)
    The foregoing statutory definitions help explain the regulation addressing the use
    of numerals to describe a fertilizer’s “guaranteed analysis.” Section 2301 of title 3 of the
    California Code of Regulations states:
    “When any series of numerals are used in labeling of or in advertising to
    describe the formula or analysis, or in connection with the name, brand, or
    trademark, such numerals shall be arranged so that the first will be the
    24.
    guaranteed percentage of nitrogen; the second, the guaranteed percentage of
    available phosphoric acid; and the third, the guaranteed percentage of
    soluble potash. The guaranteed percentages shall be consistent with the
    guaranteed analysis.”
    In accordance with this regulation, the “27-0-0” appearing in Greenfeed’s label
    informs the reader that the guaranteed percentage of nitrogen is 27 and there are no
    guaranteed percentages of available phosphoric acid or soluble potash.
    The label’s reference to slow release nitrogen also is subject to a regulation. A
    “label shall not refer to slow release of” nitrogen unless 15 percent or more of the total of
    the guarantee for nitrogen qualifies as slowly released. (Cal. Code Regs., tit. 3, § 2311,
    subd. (c).) Types of slow release nitrogen include (1) certain water insoluble products
    such as urea formaldehyde and isobutylidene; (2) encapsulated soluble fertilizers; and (3)
    products containing water soluble nitrogen such as ureaform materials, methylene diurea
    and dimethylene triurea. (Cal. Code Regs., tit. 3, § 2311, subd. (b).)
    2.     Greenfeed is a Commercial Fertilizer
    The Decision did not expressly find Greenfeed was or was not a commercial
    fertilizer. An implied finding that Greenfeed was not a commercial fertilizer cannot be
    recognized by this court because there is no substantial evidence in the record to support
    such an implied finding. (See Madera Oversight Coalition, Inc. v. County of Madera
    (2011) 
    199 Cal.App.4th 48
    , 66 [implied findings of fact must be supported by substantial
    evidence].) Based on the undisputed documentary evidence, we conclude that Greenfeed
    qualifies as a commercial fertilizer as that term is defined in section 14522.
    Greenfeed’s status as a commercial fertilizer does not automatically resolve the
    question of whether it is a pesticide. The Decision correctly states that the concepts of
    fertilizer and pesticide are not mutually exclusive. As explained below, Greenfeed’s use
    as a commercial fertilizer is relevant to one of the elements incorporated into the
    definition of spray adjuvant.
    25.
    C.     Greenfeed is a Spray Adjuvant
    1.     Sufficiency of the Evidence
    The Decision states Greenfeed is a pesticide because it is a “spray adjuvant.”11
    This determination appears to be based on two specific findings. First, the Decision
    states the Greenfeed label and Caltec documents provide “that it should be diluted and
    combined with pesticides.” The Department’s trial brief and appellate brief rely on this
    finding to support the determination that Greenfeed was a spray adjuvant. Second, the
    Decision states that being a spray adjuvant is Greenfeed’s “primary purpose.” The
    Department’s trial brief and appellate brief do not rely on this finding.
    The finding that Greenfeed’s primary purpose is as a spray adjuvant is not
    supported by substantial evidence. Greenfeed’s label, the various application guides
    produced by Caltec, and the certification by the DeptAg demonstrate that the main reason
    for using Greenfeed is to provide nitrogen—a primary plant nutrient—to the plants to
    which it is applied. The references to Greenfeed being compatible with pesticides other
    than sulfur and “compatible with a wide range of pesticides, micro and macro nutrients”
    shows that Greenfeed is capable of being mixed with some pesticides and other nutrients
    and applied together, which saves the additional time and cost of separate sprayings.
    Simple compatibility does not establish that Greenfeed’s primary purpose is as a spray
    adjuvant—that is, as an agent “intended to be used with another pesticide as an aid to the
    application or effect of the other pesticide.” (§ 12758.) Accordingly, the finding as to
    Greenfeed’s primary purpose is not supported by substantial evidence.
    Similarly, the finding that Greenfeed “should be … combined with pesticides” is
    not supported by the evidence. The word “should” is “used in auxiliary function to
    11     The Decision did not explicitly work through the elements of the definition of
    spray adjuvant and explain how Greenfeed satisfied those elements. (See § 12758
    [definition of spray adjuvant].) For instance, the Decision did not state how the phrase
    “intended to be used” was satisfied. (Ibid.)
    26.
    express obligation, propriety, or expediency <’tis commanded I ~ do so – Shak.>  .” (Merriam-
    Webster’s Collegiate Dict. (10th ed. 1999) p. 1085.) Here, the documentary evidence
    shows Greenfeed is capable of being combined with some pesticides. It does not support
    the finding that Greenfeed should be combined with pesticides.
    There is no recommendation that Greenfeed should be combined with a particular
    pesticide or category of pesticides. There is no explanation of how a combination of
    Greenfeed and a pesticide improves the benefits obtained from Greenfeed or from the
    pesticide. Furthermore, Caltec’s documents describing many applications of Greenfeed
    to various crops and plants relate to its use alone and inform the user to seek additional
    information if the user wished to mix Greenfeed with other products.
    For example, Caltec’s grass seed application guide states Greenfeed “[c]an be
    applied in multiple applications with Tilt and/or other fungicides.” The application guide
    also states “[f]ollow fungicide label when applied together” and informs the user that “[a]
    buffer may be required when applied in combination with other products” because
    Greenfeed has a pH of 9.1. Thus, the application guide does not state Greenfeed should
    be used with fungicides, but simply states it is possible and provides advice for how to
    proceed if that option is chosen.
    Caltec’s all-crop application guide for Greenfeed provides information about the
    volume of water to use if Greenfeed is applied by a boom sprayer, by air or in a low
    volume spray. The next paragraph states:
    “If combined with Crop Protection Chemicals (CPC), maintain proper
    manufacturer recommended dilutions. Always jar test CPC combinations
    for compatibility before tank mixing, and perform small trial applications
    and observe for any combination injury. As GREENFEEDTM has a high
    alkaline pH (9.1), a buffering agent should be used when mixing with those
    CPC’s that are sensitive to high pH solutions.”
    27.
    As with other Caltec documents, this guide shows that under certain conditions it
    is possible to mix Greenfeed with pesticides, but it does not reasonably support the
    inference that Greenfeed should be used with pesticides—that is, it would be improper to
    use Greenfeed alone.
    In summary, the two express findings of fact relating to Greenfeed’s primary
    purpose and use in combination with pesticides are not supported by substantial evidence.
    In addition, the finding that Greenfeed should be diluted is not completely accurate.
    Caltec’s document describing the foliar benefits of Greenfeed states “CAN BE USED
    UNDILUTED ON SOME CROPS” as one of its 14 bullet points. Thus, an accurate
    finding would state that Greenfeed usually is diluted before application.
    2.     Application of Definition of Spray Adjuvant
    The statutory elements of a “spray adjuvant” are (1) an agent, (2) intended for use
    with another pesticide, (3) “as an aid to the application or effect of the other pesticide,”
    (4) which is sold in a separate package. (§ 12758.)
    The first statutory element requires the substance to be “any wetting agent,
    spreading agent, deposit builder, adhesive, emulsifying agent, deflocculating agent, water
    modifier, or similar agent.” (§ 12758.) Caltec’s document describing the foliar benefits
    of Greenfeed contains bullet points stating: “COMPATIBLE WITH PESTICIDES
    OTHER THAN SULFUR”; “EXCELLENT STICKING AND SPREADING
    QUALITIES”; and “USE AS CARRIER FOR MOST PESTICIDES.” The references to
    Greenfeed’s spreading qualities and its use as a carrier for most pesticides adequately
    support the finding that Greenfeed is a “spreading agent” for purposes of section 12758.
    The second element of the definition of spray adjuvant addresses whether the
    substance was “intended to be used with another pesticide.” (§ 12758.) Regulation 6145
    defines “intended to be used” in various ways. The definition is satisfied when, among
    other things, a person selling the substance states or implies (by labelling or otherwise)
    28.
    that “the substance, either by itself or in combination with any other substance, can or
    should be used as a pesticide.” (Regulation 6145, subd. (a)(1), italics added.) Here, the
    bullet points in Caltec’s document clearly implies that Greenfeed could be used as a spray
    adjuvant (a type of pesticide) by stating Greenfeed is compatible with pesticides other
    than sulfur and can be used as a carrier for most pesticides. Therefore, we conclude the
    bullet points constitute substantial evidence supporting a finding that Greenfeed was
    “intended to be used with another pesticide.” (§ 12758.)
    The third element addresses whether Greenfeed’s use with another pesticide is
    intended “as an aid to the application or effect of the other pesticide.” (§ 12758.) The
    reference in the bullet points to Greenfeed’s sticking and spreading qualities adequately
    supports a finding that Greenfeed was intended to aid the application of a herbicide,
    fungicide or insecticide by helping that pesticide spread on, and stick to, the foliage of the
    plants to which it is applied.12
    As to the fourth element, the invoices and labels contained in the administrative
    record demonstrate Greenfeed was sold in separate packaging. Caltec does not argue
    otherwise. Consequently, we conclude that there is sufficient evidence to support the
    finding that Greenfeed is a spreading agent, sold in separate packaging, and intended to
    be used as an aid to the application of other pesticides. Thus, Greenfeed satisfies the
    statutory elements of a spray adjuvant. (§ 12758.) Accordingly, the Department’s
    determination that Greenfeed is a pesticide must be affirmed.
    12      For purposes of making a complete record, we conclude Greenfeed does not met
    the ingredient-based definition of “intended to be used” contained in subdivision (c) of
    Regulation 6145 because Greenfeed has a significant commercially valuable use as a
    fertilizer that provides plants with nitrogen, one of the three primary plant nutrients.
    Also, a bullet point in the document describing Greenfeed’s foliar benefits states it can be
    used undiluted on some crops. This undiluted use shows that Greenfeed does not need to
    be used with other products such as pesticides to have commercial value, a fact which is
    confirmed by Greenfeed’s registration by the DeptAg as a commercial fertilizer.
    29.
    IV.    TERRA TREAT
    A.     Background
    1.     Administrative Decision
    Part F of the analysis section of the Decision states there is ample evidence to
    support the Department’s assertion “that Terra Treat is a spray adjuvant that Caltec
    claimed could be used to disburse other pesticides into the soil.” The evidence includes a
    label that described Terra Treat as a soil surfactant/penetrant designed to uniformly
    distribute fertilizer, pesticides and/or water throughout the root zone. Based on invoices
    for seven sales of Terra Treat, the Department fined Caltec a total of $7,000—that is,
    $1,000 for each sale of the unregistered pesticide.
    2.     Terra Treat’s Certification
    The March 2015 declaration of Caltec’s president and owner states Caltec held a
    certificate of registration for fertilizing materials from the DeptAg that listed Terra Treat
    as an “Auxiliary Soil and Plant Substance.” A copy of the certificate of registration is
    attached to the declaration. The declaration states Caltec has held a certificate of
    registration for Terra Treat since approximately 1995.
    B.     Statutory Construction
    1.     Contentions of the Parties
    Caltec contends that because Terra Treat is registered with the DeptAg as an
    “auxiliary soil and plant substance” and the statutory definition of “auxiliary soil and
    plant substance” excludes pesticides (§ 14513), it follows that Terra Treat is not a
    pesticide. Caltec argues California’s two statutory schemes relating to fertilizing
    materials and pesticides must be read together and the term “pesticide” given the same
    meaning in each scheme. In Caltec’s view, the statutory language evinces an intent to
    avoid the duplicative regulation of auxiliary soil and plant substances as pesticides, and
    vice versa. This argument suggests that Caltec regards the DeptAg’s registration of Terra
    30.
    Treat as an auxiliary soil and plant substance is a final administrative determination that
    Terra Treat is not a pesticide under section 12753.
    The Department argues the term “pesticide” used in the exception to the statutory
    definition of auxiliary soil and plant substance does not have the same meaning as the
    term “pesticide” defined in section 12753. In the Department’s view, which was adopted
    in the Decision, section 14513’s exclusion used the term “pesticide” in its ordinary sense,
    rather than in the technical sense set forth in section 12753. Under this statutory
    interpretation, it is possible for a product to be a pesticide under the technical elements of
    section 12753 and also be an auxiliary soil and plant substance under the statutory
    scheme governing fertilizing materials.
    2.     Statutory Text
    Chapter 5 of division 7 of the Food and Agricultural Code governs fertilizing
    materials and contains provisions for licensing sellers, registering products, labeling,
    inspections, and procedures for prosecuting violations. (§§ 14501–14682.) In contrast,
    chapter 2 of the same division governs pesticides. (§§ 12751–13192.)
    “Fertilizing materials” is defined as “any commercial fertilizer, agricultural
    mineral, auxiliary soil and plant substance, organic input material, or packaged soil
    amendment.” (§ 14533.) Each component of this definition, in turn, is defined by
    statute. (§§ 14522 [commercial fertilizer], 14512 [agricultural mineral], 14513 [auxiliary
    soil and plant substance], 14550.5 [organic input material], 14552 [packaged soil
    amendment].) “Auxiliary soil and plant substance” includes, without limitation, (1)
    substances applied to soil for corrective purposes; (2) substances intended to improve
    desirable characteristics in plants, such as germination, growth or yield; and (3)
    substances intended to produce chemical, biological or physical change in soil.
    (§ 14513.) The statute also provides that the term “auxiliary soil and plant substance”
    “does not include commercial fertilizers, agricultural minerals, pesticides, soil
    31.
    amendments except biochar, or manures.” (§ 14513, italics added; see § 14545
    [manure].) In comparison, the statutory definitions of “pesticide” and “spray adjuvant”
    do not contain an exclusion for “auxiliary soil and plant substance.” (See §§ 12753,
    12758.) The parties dispute how these statutory definitions fit together.
    3.     Meaning of the Word “Pesticide”
    For purposes of this opinion, we assume without deciding that Caltec has properly
    interpreted the statutory scheme and the term “pesticide” appearing in section 14513’s
    exclusion has the same meaning as the term “pesticide” defined by section 12753. Under
    this assumption, if a material qualifies as a “pesticide” subject to regulation under chapter
    5 of division 7 of the Food and Agricultural Code, it is not an “auxiliary soil and plant
    substance” subject to regulation under the chapter governing fertilizing materials because
    of the exclusion in section 14513.
    4.     Impact of Terra Treat’s Registration
    The next legal question presented is whether the DeptAg’s registration of Terra
    Treat as an “auxiliary soil and plant substance” means Terra Treat is not a “pesticide”
    subject to regulation by the Department under chapter 2 of division 7 of the Food and
    Agricultural Code. Based on the circumstances of this case, we conclude the registration
    does not prevent Terra Treat from being a pesticide subject to regulation by the
    Department.
    The definition “auxiliary soil and plant substance” excludes “pesticides.”
    (§ 14513.) In comparison, the definition of “pesticides” set forth in section 12753 does
    not exclude “auxiliary soil and plant substance” or the broader term “fertilizing
    materials.” When these provisions are read together, the classification of a material as a
    “pesticide” precludes it from also being classified as an “auxiliary soil and plant
    substance.”
    32.
    Here, the sequence of the determinations was different. Terra Treat was registered
    as an “auxiliary soil and plant substance” before the Department determined it was a
    “pesticide.” As a result, the narrow question presented is whether the DeptAg’s
    registration of Terra Treat as an “auxiliary soil and plant substance” precludes the
    Department from subsequently determining Terra Treat was a “spray adjuvant” under
    section 12758 and, thus, a “pesticide” under section 12753.
    Caltec’s argument is the equivalent of claiming that the DeptAg’s registration is a
    binding determination that Terra Treat is not a “pesticide.” The parties have not analyzed
    the issue from this perspective. For instance, they have not set forth any rules of law that
    identify when a determination by one administrative agency is binding upon another
    administrative agency. One set of legal rules addressing this topic is the doctrine of
    collateral estoppel, as modified for administrative decisions.
    “For an administrative decision to have collateral estoppel effect, it and its prior
    proceedings must possess a judicial character. [Citation.] Indicia of proceedings
    undertaken in a judicial capacity include a hearing before an impartial decision maker;
    testimony given under oath or affirmation; a party’s ability to subpoena, call, examine,
    and cross-examine witnesses, to introduce documentary evidence, and to make oral and
    written argument; the taking of a record of the proceeding; and a written statement of
    reasons for the decision.” (Pacific Lumber Co. v. State Water Resources Control Bd.
    (2006) 
    37 Cal.4th 921
    , 944.) Here, the DeptAg’s registration of Terra Treat did not
    possess a judicial character and, therefore, the registration has no collateral estoppel
    effect on the Department.
    In the absence of any other legal doctrine supporting the conclusion that the
    Department is bound by the DeptAg’s registration, we conclude the registration of Terra
    Treat as an “auxiliary soil and plant substance” did not preclude the Department from
    determining Terra Treat was also a pesticide subject to regulation under chapter 2 of
    division 7 of the Food and Agricultural Code. Therefore, the Department did not act in
    33.
    excess of its jurisdiction for purposes of subdivision (b) of Code of Civil Procedure
    section 1094.5.
    C.     Sufficiency of the Evidence
    Caltec also contends the evidence is insufficient to support the Department’s
    finding that Terra Treat was a spray adjuvant. We disagree.
    1.     Documents in Administrative Record
    Caltec asserts that “Terra Treat is a soil wetting agent that is intended to be applied
    to soil to improve water penetration.” One of the documents cited by Caltec to support
    this assertion states that “managers often experience problems getting irrigation water to
    effectively and efficiently penetrate soil” (boldface and italics omitted) and explains that
    the surface tension of water may prevent it from physically penetrating the soil surface
    and root zone. The document then states:
    “The surfactants in Terra Treat Soil Penetrant are specifically designed to
    improve the spreading and penetration of water applied through irrigation
    systems. Injecting Terra Treat into irrigation system reduces the surface
    tension of water, which facilities penetration of irrigation water.
    “Terra Treat surfactant molecules in the irrigation water also attach to the
    water repellent ‘coating’ on thatch material and on the soil surface. This
    increases the adhesion between applied water and these surfaces.…
    “The net effect of reduced surface tension and increased adhesion of
    applied water at the water thatch and water soil interface will enhance
    spreading and penetration into the soil and root profile.
    “The improved pattern of penetration, spreading, and hydration allows
    water to move more quickly and more efficiently into the soil. Reduction
    of water loss due to efficiently into the soil. Reduction of water loss due to
    surface evaporation and run-off can be expected.”
    The second page of the document asks, “EVER WONDER WHERE YOUR
    WATER AND PESTICIDES WENT?” That page states Terra Treat distributes water
    laterally and uniformly beneath the soil surface 8 to 12 inches deep. It also states Terra
    34.
    Treat can be applied through drip, flood, furrow, micros, or sprinklers and added with soil
    pesticides.
    The label for Terra Treat appears in the administrative record at pages 1387 to
    1388 and 1509. Each version of the label states: “A SOIL
    SURFACTANT/PENETRANT DESIGNED TO UNIFORMLY DISTRIBUTE
    FERTILIZER, PESTICIDES, AND/OR WATER THROUGHOUT THE ROOT ZONE.”
    A technical information sheet dated May 2011 for Terra Treat states:
    “SIGNIFICANTLY INCREASES THE EFFECTIVENESS OF SOIL-INJECTED,
    BAND-APPLIED LIQUID FERTILIZERS, INSECTICIDES, FUMIGANTS AND
    HERBICIDES.” The technical information sheet includes the following entry:
    “Chemistry: Non-ionic, polyol soil wetting agent.”13
    2.     Application of Statutory Definition of “Spray Adjuvant”
    The statutory elements of a “spray adjuvant” are (1) any wetting or similar agent,
    (2) intended for use with another pesticide, (3) “as an aid to the application or effect of
    the other pesticide,” (4) which is sold in a separate package. (§ 12758.)
    Terra Treat easily satisfies the first and fourth elements. Caltec’s opening brief
    states “Terra Treat is a soil wetting agent” and the phrase “soil wetting agent” appears in
    the technical information sheet dated May 2011. As to packaging, the labels in the record
    demonstrate Terra Treat is sold in separate containers or packaging rather than being
    premixed by Caltec with other substances, such as fertilizers or other pesticides.
    As to the second and third elements, Caltec contends “there is nothing in the
    record demonstrating that Terra Treat is intended to be used with other pesticides to
    improve the efficacy of the other pesticide.” One shortcoming of this argument is that it
    13     Thus, the documents describing Terra Treat are distinguishable from the
    documents describing Greenfeed in that Terra Treat is explicitly referred to as a wetting
    agent and no document describes Greenfeed as an “agent” of any sort.
    35.
    overlooks part of the statutory definition.14 The definition is not limited to agents that aid
    the effect (i.e., improve the efficacy) of another pesticide. It also covers agents that are
    “an aid to the application … of the other pesticide.” (§ 12758, italics added.) Terra
    Treat’s label states it is capable of uniformly distributing pesticides throughout the root
    zone. This statement about uniform distribution is sufficient to support the factual
    finding that Terra Treat is an aid to the application of pesticides. Accordingly, the third
    element has sufficient evidentiary support.
    As to whether Terra Treat is intended for use with another pesticide, the regulatory
    definition of “intended to be used” is satisfied when the seller of a substance claims or
    states, by labeling or otherwise, that the substance, by itself or in combination with any
    other substance, can be used as a pesticide. (Regulation 6145, subd. (a)(1).) A claim that
    a substance can “be used as a pesticide” necessarily includes the more specific claim that
    the substance can be used as a spray adjuvant because the statutory definition of
    “pesticide” includes “spray adjuvant.” (§ 12753.) Here, Caltec has claimed that Terra
    Treat can be used as a spray adjuvant by stating it was designed to uniformly distribute
    pesticides throughout the root zone.
    Consequently, we conclude that there is sufficient evidence to support the finding
    that Terra Treat is a wetting agent, sold in separate packaging, and intended to be used as
    an aid to the application of other pesticides. Accordingly, the Department’s findings and
    conclusions as to Terra Treat, along with the fine of $7,000, shall be upheld.
    14      A second shortcoming is Caltec’s failure to address the Terra Treat technical
    information sheet dated May 2011 and its statement that Terra Treat significantly
    increases the effectiveness of soil-injected, band-applied insecticides, fumigants and
    herbicides. This statement is the equivalent of saying Terra Treat is “an aid to the …
    effect of [a] pesticide.” (§ 12758.)
    36.
    V.     KELPAK
    A.     Background
    1.     Violations Alleged
    The Notice of Proposed Action alleged Kelpak, as a plant growth regulator, is a
    pesticide product. It also alleged (1) Caltec had sold Kelpak in California a total of 282
    times from June 1, 2010, through June 30, 2014; (2) the sales totaled $4,165,862.50; (3)
    during that period, Kelpak was not registered as a pesticide in California; and (4) the
    sales of the unregistered Kelpak violated section 12993. The Notice of Proposed Action
    stated the Department sought a penalty of $2,000 per sale, which totaled $564,000.
    2.     The Decision
    The Decision states that (1) pesticides include plant growth regulators, (2) auxins
    and cytokinins are plant growth regulators, and (3) Kelpak is a liquid auxin concentrate
    and, therefore, a plant growth regulator. The Decision acknowledged Caltec’s factual
    assertions that Kelpak is derived solely from edible seaweed, does not include added
    plant hormones, and is registered as an organic input material with the DeptAg. The
    Decision stated: “Auxins in seaweed are plant hormones which in un-concentrated form
    is possibly a fertilizer. But in concentrated form seaweed auxins are probably plant
    growth regulators or pesticides, not fertilizers.”15
    The Director imposed the penalty recommended in the Notice of Proposed Action.
    Thus, Caltec was fined $2,000 for each of the 282 sales of Kelpak that violated section
    12993, or a total of $564,000.
    15     A parenthetical citation immediately after this statement directs the reader to see
    the discussion in G & M Farms, Inc. v. Britz-Simplot Grower Solutions, LLC (E.D.Cal.
    May 28, 2013, No. 1:13-CV-0368 LJO MJS) 
    2013 U.S. Dist. LEXIS 75458
     (G & M
    Farms).
    37.
    B.     Evidence Presented
    1.     Documents
    Caltec’s invoices for its sales of Kelpak include a box labeled “Description.” The
    entries in this box describe Kelpak as a “Liquid Auxin Concentrate.” Kelpak’s label
    describes it as a “Liquid Seaweed Concentrate” and an “Organic Plant Nutrient.” The
    label includes a logo stating it is a material registered with the Washington State
    Department of Agriculture for use in organic agriculture. The label also directs users to
    refer to the Kelpak Application Guide for specific crop recommendations.
    A “Kelpak Guide Manual” included in the administrative record contains sections
    for (1) product specifications and (2) mode of action and responses. The product
    specifications state the active ingredients are “Natural Auxins 11 mg / litre” and “Natural
    Cytokinins 0.031 mg / litre.” The first two paragraphs of the section labeled “MODE OF
    ACTION AND RESPONSES” state:
    “Kelpak is a plant bioregulator made from the seaweed species
    Ecklonia maxima (commonly known as kelp), and found in the cold waters
    of[f] the South African West Coast. This species has a prolific growth rate,
    due mainly to the presence of the plant hormone groups auxins and
    cytokinins. The cell sap containing these hormones is extracted from
    freshly-harvested kelp with the unique cell burst technology, patented
    worldwide. No heat, freezing or harsh chemicals are used to break the cell
    walls in the extraction process. This ensures that the delicate compounds
    found in the kelp are maintained in their active form in Kelpak. The natural
    high auxin to low cytokinin ratio in the fresh kelp is therefore maintained in
    the end product. The Institute of Marketecology (IMO), BCS Oko-
    Garantie, The UK Soil Association, Australian Biological Farmers and SGS
    have accredited this organic product for use in organic agriculture.
    “This auxin-dominated extract stimulates prolific adventitious root
    formation when Kelpak is applied to almost any plant. This drastic
    increase in root tips leads to an increased level of cytokinins in treated
    plants, as this group of hormones is mainly produced in root tips. The
    increased root volume and number of root tips also increases moisture and
    nutrient uptake from the soil. The improved nutrient status, together with
    the higher level of cytokinin in the plant, gives better top growth which
    causes the increase in yield and quality of crops. The improved root system
    38.
    also makes the plant more resistant to stresses such as drought,
    waterlogging, soil nutrient deficiency and salinity, nematode infestations
    and soil-borne diseases.”
    The last paragraph in this section refers to Kelpak “as a cost effective agricultural
    biostimulant.” A June 2010 Kelpak Guide for new plantings, trees and vines, includes
    the line: “Use Kelpak auxin concentrate plant growth regulator as follows.” This guide
    includes Caltec’s name, address and phone numbers. Caltec’s 2008 product guide lists
    Kelpak under the heading “Auxin Concentrate.”
    Exhibit D to the investigation summary prepared by Chowdhury was a September
    13, 2012, press release issued by the EPA. The press release announced three
    enforcement actions by the EPA against Missouri pesticide distributors involving the sale
    of plant growth regulators, which are regulated as pesticides under FIFRA. The release
    stated: “FIFRA defines plant growth regulators as substances intended to accelerate or
    retard the growth of plants. Among other things, substances considered to be plant
    regulators may include hormone additives intended to stimulate plant root growth or
    fruiting, such as gibberellins, auxins, and cytokinins derived from seaweed. Products
    containing these additives are often marketed as fertilizers, but such claims do not exempt
    products from regulation as pesticides.”
    2.     Caltec’s Evidence
    The March 2015 declaration of Caltec’s owner states Caltec holds a certificate of
    registration for organic input material from the DeptAg for Kelpak liquid seaweed
    concentrate and includes a copy of the certificate. Also attached to the declaration is a
    copy of a material registration certificate from the Washington State Department of
    Agriculture, which states Kelpak has “been verified to comply with the USDA National
    Organic Standards (7 CFR Part 205).”
    Caltec submitted a March 2015 declaration of Adriaan Francois Lourens, Ph.D.
    Dr. Lourens obtained a Ph.D. in plant physiology from the University of California,
    Davis and bachelor’s and master’s degrees from the University of Stellenbosch, South
    39.
    Africa. Dr. Lourens works for Kelp Products (Pty) Ltd., the company that developed and
    manufactures Kelpak. Dr. Lourens’s declaration asserts Kelpak (1) is derived entirely
    from the edible seaweed species Ecklonia maxima, (2) is nontoxic, (3) includes soluble
    potash (K2O) and lower levels of calcium and magnesium, and (4) contains no hormone
    additives. The declaration also asserts “Kelpak was developed with the sole intention
    that it be sold and used as an organic plant nutrient.”16
    Dr. Lourens’s declaration states: “All seaweed species naturally contain varying
    amounts of auxins and cytokinins, plant hormones that are necessary to the normal
    growth of plants. Similarly, Ecklonia maxima has naturally-occurring auxins and
    cytokinins, with the auxin levels being higher than cytokinin levels.” The declaration
    also states the levels of auxin and cytokinin listed on Kelpak’s label—11 mg/liter and
    0.03 mg/liter—were obtained from a typical bioassay for auxin-like and cytokinin-like
    activity and then asserts: “These values of auxins and ctyokinins were later found to be a
    gross over-estimation of what were found by high technology physical analyses of the
    product.” The declaration does not state how the timing of these later analyses relates to
    the period covered by the Notice of Proposed Action. In particular, it does not state when
    the analyses were completed or describe how the new information affected the labeling
    and marketing of Kelpak, if at all.17 Thus, the new information about grossly over-
    estimated auxin levels is not linked to what Caltec stated or implied about Kelpak in
    16      We note that Dr. Lourens’s declaration did not attach any of his journal articles
    discussing seaweed concentrate. (See Ferreira & Lourens, The efficacy of liquid seaweed
    extract on the yield of canola plants (2002) 19(3) S. Afr. J. Plant Soil 159, 161 [“Liquid
    seaweed concentrate (Kelpak) … contains natural plant growth regulators that are high in
    auxins and low in cytokinins”; “Kelpak … appeared to be an effective and consistent
    growth regulator for increasing canola yield”].) We have not relied on this or any other
    article authored by Dr. Lourens in deciding this appeal.
    17     The new findings about Kelpak’s (unspecified) auxin levels resulting from the
    high technology physical analyses did not affect Caltec’s invoices from May 2014, which
    continued to describe Kelpak as a “Liquid Auxin Concentrate.”
    40.
    connection with the 282 sales that are the subject to the Notice of Proposed Action. (See
    Regulation 6145, subd. (a).)
    Caltec also submitted a March 2015 declaration of Roy Slack, the current
    managing director of Kelp Products (Pty) Ltd., which states he is responsible for the
    development of Kelpak’s North America markets. Slack’s declaration states that since
    Kelpak distribution began in the United States, neither the EPA nor any state other than
    California has characterized Kelpak as a pesticide. Slack’s declaration also states Kelpak
    is registered as an organic input material with the DeptAg and, to maintain this specific
    type of registration, additional fees must be paid and labeling requirements satisfied.
    C.     Kelpak’s Registration as an Organic Input Material
    It is undisputed that Kelpak is registered with the DeptAg as an organic input
    material. Section 14550.5 defines “organic input material” as “any bulk or packaged
    commercial fertilizer, agricultural mineral, auxiliary soil and plant substance, specialty
    fertilizer, or soil amendment, excluding pesticides, that is to be used in organic crop and
    food production and that complies with” certain national organic standards contained in
    the Code of Federal Regulations. (Italics added.) This definition, like the definition of
    “auxiliary soil and plant substance” set forth in section 14513, excludes “pesticides.”
    Caltec argues that Kelpak is not a plant growth regulator and, thus, is not a
    pesticide because the DeptAg has registered Kelpak as an organic input material. First,
    on the question of statutory interpretation, we conclude the Legislature intended
    “pesticide” to mean the same thing in section 14550.5 as it does in sections 12753 and
    14513. Second, as in our analysis of Terra Treat, we conclude the DeptAg’s
    determination that a substance is a particular type of fertilizing material with a definition
    that excludes pesticides is not a final and binding determination that the material is not a
    pesticide. Consequently, Kelpak’s registration as an organic input material does not
    preclude the Department from determining it is a pesticide.
    41.
    D.     Sufficiency of the Evidence
    First, Caltec argues the record does not contain sufficient evidence to support the
    finding that all types of cytokinins and auxins, regardless of their intended use or physical
    composition, are plant growth regulators and pesticides. This argument need not be
    discussed in detail because the Decision does not contain such a broad finding. Instead,
    the Decision clearly states Kelpak is a liquid that concentrates the auxins contained in
    seaweed and was intended for use as a liquid auxin concentrate. Thus, the Decision does
    not relate to all types of auxins, whether or not they are concentrated.
    Second, Caltec argues substantial evidence does not support the finding that
    seaweed auxins in concentrated form are probably plant growth regulators and are not
    fertilizers. The Decision made the general observation that “in concentrated form
    seaweed auxins are probably plant growth regulators, not fertilizers.” Then, the Decision
    addressed the specific question presented by the sales of Kelpak by stating “Caltec sold
    Kelpak as a Liquid Auxin Concentrate on each invoice—a plant growth regulator and not
    a plant nutrient.”
    Substantial evidence supports the explicit finding that Caltec sold Kelpak as a
    liquid auxin concentrate. Caltec’s invoices contain that description of Kelpak. The
    invoices do not state Kelpak contains any primary plant nutrient, any secondary plant
    nutrient, or any micronutrients.18 Thus, the description in the invoices supports the
    inference that Kelpak is intended to be used as an auxin concentrate, rather than intended
    to supply a plant nutrient not mentioned in the label or invoice.19 In addition, Caltec’s
    18     Nitrogen, available phosphoric acid, and soluble potash are primary plant
    nutrients. (§ 14556.) The secondary plant nutrients are calcium, magnesium and sulfur,
    alone or in combination. (§ 14559.) “‘Micronutrients’ means boron, chlorine, cobalt,
    iron, manganese, molybdenum, sodium, or zinc, alone or in any combination.”
    (§ 14546.)
    19     Under section 12756, the definition of regulating plant growth does “not include
    the use of substances to the extent that they are intended as plant nutrients, trace
    elements, nutritional chemicals, plant inoculants, and soil amendments.” Here, the
    42.
    2008 product guide lists Kelpak as an auxin concentrate. The product specifications
    given in a Kelpak guide manual state the active ingredients in Kelpak are natural auxins
    (11 mg/liter) and natural cytokinins (0.031 mg/liter). These figures are consistent with
    the information provided in Dr. Lourens’s declaration. These documents constitute
    substantial evidence that Kelpak was intended to be used as an auxin concentrate.
    Substantial evidence also supports the finding that, as a liquid auxin concentrate,
    Kelpak was sold as a plant growth regulator. The Kelpak Guide Manual includes a
    section labeled “MODE OF ACTION AND RESPONSES” that describes Kelpak as “a
    plant bioregulator made from the seaweed species Ecklonia maxima”; an “auxin-
    dominated extract”; and “a cost effective agricultural biostimulant.” Moreover, Caltec’s
    June 2010 Kelpak guide for new plantings, trees and vines, uses the phrase “Kelpak auxin
    concentrate plant growth regulator.” Besides the explicit use of the term “plant growth
    regulator,” the use of the terms “plant bioregulator” and “agricultural biostimulant”
    reasonably support the inference that Kelpak was sold as a plant growth regulator and not
    a plant nutrient. Furthermore, Caltec’s argument that the weight of the evidence supports
    a finding that Kelpak was intended to be used as an organic input material and plant
    nutrient is off point, because the applicable test for reviewing the evidence is the
    substantial evidence standard, which does not allow a reviewing court to reweigh the
    evidence in the record. (See Montebello Rose Co. v. Agricultural Labor Relations Bd.
    (1981) 
    119 Cal.App.3d 1
    , 21 [power of appellate court reviewing findings of a lower
    tribunal begins and ends with determining whether there is substantial evidence,
    contradicted or not, that supports the findings].) In short, the possibility that the trier of
    fact could have drawn other inferences from the evidence does not establish factual error.
    In sum, we conclude substantial evidence supports a finding that Kelpak is a mixture of
    Director was not compelled by the evidence to find that the intended use of Kelpak was
    as a plant nutrient. As a result, the Director’s determination that the exception did not
    apply to Kelpak does not constitute error.
    43.
    substances “intended to be used for … regulating plant growth” and, therefore, qualifies
    as a “pesticide” under section 12753. (See Regulation 6145, subd. (a).)
    E.     Extra-Record Evidence*
    1.     Contentions
    Caltec contends the hearing officer erred in relying on extra-record evidence
    obtained unilaterally—namely, an unreported federal district court order. (See G & M
    Farms, supra, 
    2013 U.S. Dist. LEXIS 75458
    .) Caltec contends the hearing officer relied
    on G & M Farms as evidentiary support for its factual finding that “‘in concentrated form
    seaweed auxins are probably growth regulators or pesticides, not fertilizers.’”
    In response, the Department contends (1) G & M Farms was not extra-record
    evidence, but legal authority and (2) even unpublished federal district court opinions may
    be referred to as persuasive authority. (See Haligowski v. Superior Court (2011) 
    200 Cal.App.4th 983
    , 990, fn. 4 [unpublished federal opinion treated as convincing].) Thus,
    the Department argues G & M Farms may be cited as persuasive authority to illuminate
    the hearing officer’s independent determination that concentrated auxins are plant growth
    regulators and, therefore, pesticides.
    The parties’ contentions raise the question whether the hearing officer (1) relied on
    G & M Farms as evidence to support a finding of fact, (2) relied on it as authority for a
    legal conclusion about plant growth regulators being pesticides, or (3) relied on it in some
    other manner.
    2.     G & M Farms
    We begin our analysis of this question by reviewing the opinion. In G & M
    Farms, the district court granted a motion to dismiss for lack of federal question or
    diversity jurisdiction. (G & M Farms, supra, 
    2013 U.S. Dist. LEXIS 75458
    , p. 4.) The
    plaintiff’s causes of action alleged the application of Bloom Blend and Acadian Seaweed
    *      See footnote, ante, page 1.
    44.
    Concentrate damaged its blueberry crop. (Ibid.) The decision stated: “Unbeknownst to
    Plaintiff at the time, [Bloom Blend and Acadian Seaweed Concentrate] is not only a
    fertilizer but is also a plant growth regulator. It affects the physiology of plants and
    changes a plant’s growth and production.” (Ibid.) The court granted the motion to
    dismiss based on its conclusion that FIFRA does not create a private right of action. (Id.
    at p. 3.) In other words, only certain federal and state agencies may bring actions to
    enforce FIFRA. (Ibid.) As a result, the plaintiff had not stated a federal claim that could
    be pursued in federal court.
    To place the statements in G & M Farms about plant growth regulators in context,
    we note that FIFRA defines “plant regulator” as any substance “intended, through
    physiological action, for accelerating or retarding the rate of growth … of plants,” and
    excludes substances to the extent that they are intended as plant nutrients, trace elements,
    nutritional chemicals, plant inoculants and soil amendments. (
    7 U.S.C. § 136
    (v).)
    FIFRA’s definition of “pesticide” includes any substance “intended for use as a plant
    regulator.” (
    7 U.S.C. § 136
    (u)(2).) FIFRA does not explain how to distinguish between
    a plant regulator that accelerates growth and a plant nutrient used in synthesizing
    additional structures, such as leaves, stems, fruit and seeds. G & M Farms did not
    address how California’s statutes should be interpreted or applied to a seaweed
    concentrate.
    3.    Role in the Decision’s Analysis
    Here, the Decision relied on G & M Farms to support its general observation that
    in concentrated form, seaweed auxins are probably plant growth regulators, not
    fertilizers. The use of the word “probably” establishes the general nature of the statement
    and demonstrates the hearing officer and the Director realized the statement was not
    controlling in this particular case. The reason the statement is not controlling is that the
    test for whether a substance is a plant growth regulator under California statute depends
    45.
    on its intended use, which may vary from case to case and product to product. (§ 12753.)
    The Decision recognized the importance of intent in the explicit findings that “Kelpak is
    a plant growth regulator and was sold as such by Caltec.” (Italics added; see Regulation
    6145, subd. (a) [seller’s intent].) Therefore, considering the Decision as a whole, we
    interpret it as relying on G & M Farms to support the general observation about
    concentrated seaweed auxins and then basing its specific findings about Kelpak on the
    evidence contained in the record. Accordingly, the record before us does not establish
    the Department abused its discretion by referring to G & M Farms in the Decision as
    support for a general observation.
    F.       Agency Web site and Publications*
    Caltec contends the hearing officer erred in noticing and relying on the truth of
    statements made in unofficial agency Web sites and publications. In Caltec’s view,
    statements made in the EPA’s informal materials are not subject to judicial notice, do not
    constitute credible or relevant evidence, and are not administrative interpretations entitled
    to deference.
    The Department contends the hearing officer did not commit error in admitting
    and considering the materials because (1) section 12999.4 does not establish any
    standards regarding the admissibility of evidence; (2) the provisions for an informal
    hearing under California’s Administrative Procedures Act set forth in Government Code
    section 11445.40, though not mandatory, would not have compelled the exclusion of the
    materials; and (3) the formal hearing procedures in Government Code section 11513,
    though not applicable, would have allowed the admission of the materials. In addition,
    the Department argues that no prejudice resulted from the admission of the EPA’s fact
    sheet on cytokinins or the EPA’s question-and-answer Web page.
    *      See footnote, ante, page 1.
    46.
    Here, Caltec’s appellate briefs have not identified the standard of admissibility
    governing the hearing officer’s decisions as to the admissibility of evidence. Caltec
    simply refers to the Evidence Code provisions governing judicial notice as if those
    provisions were controlling. Government Code sections 11445.40 and 11513
    demonstrate that the rules of admissibility in administrative hearings are more relaxed
    than the standards that apply in judicial proceedings. Despite the Department’s reference
    to these sections and its argument that neither section applied, Caltec’s reply brief failed
    to identify a standard of admissibility applicable the hearing officer’s evidentiary
    decisions. To the extent that Caltec impliedly argues the technical provisions in the
    Evidence Code applied, we reject that argument as inconsistent with section 12999.4 and
    the provisions of the Administrative Procedures Act, neither of which provide the
    Evidence Code is applicable to the administrative proceeding. As a result of Caltec’s
    failure to establish the applicable standard for admissibility, Caltec has failed to
    demonstrate that the hearing officer violated an applicable legal standard when it
    admitted the EPA’s documents.
    DISPOSITION
    The judgment is affirmed. Appellant’s November 27, 2018, request for judicial
    notice of legislative history is granted. Respondents shall recover their costs on appeal.

    MEEHAN, J.
    47.
    POOCHIGIAN, Acting P.J., concurring,
    I concur in the judgment but write separately to discuss several peculiarities of
    pesticide regulation in California.
    I.     Regulations Significantly Limit Fact-finders’ Ability to Weigh Competing Indicia
    of Intent
    In most contexts, the intent of an actor is determined by a finder-of-fact weighing
    conflicting inferences from various pieces of circumstantial evidence. As this case
    demonstrates, the concept of intent is also important in the realm of pesticide regulation.
    The statutory definition of pesticide includes any substance “intended to be used for”
    certain purposes (e.g., destroying or preventing pests, etc.) (Food & Agr. Code, § 12753,
    subd. (b).)1 By itself, this language would suggest a finder-of-fact can look to various
    factors to try to discern the intent of the seller in a particular transaction. However,
    attendant administrative regulations found at 3 California Code of Regulations section
    6145 (Regulation 6145) severely limit the fact-finder’s prerogative.
    Under Regulation 6145, a substance is “considered to be ‘intended to be used’ ”
    for a pesticidal purpose if any of the following three circumstances apply:
    “(a) A person who distributes or sells the substance claims, states, or
    implies, by labeling or otherwise, that:
    “(1) The substance, either by itself or in combination with any
    other substance, can or should be used as a pesticide; or
    “(2) The substance consists of or contains an active ingredient and
    can be used to manufacture a pesticide; or
    “(b) A person who distributes or sells the substance has actual or
    constructive knowledge that the substance will be used, or is intended by
    the user to be used, as a pesticide; or
    1All further statutory references are to the Food and Agricultural Code unless
    otherwise stated.
    “(c) The substance consists of or contains one or more active ingredients
    and has no significant commercially valuable use as distributed or sold
    other than:
    “(1) Use as a pesticide, by itself or in combination with any other
    substance; or
    “(2)    Use in the manufacture of a pesticide.” (Regulation 6145.)
    By using the disjunctive “or” between subdivision (a), (b), or (c), Regulation 6145
    provides that if any one of the several factors applies, then the requisite “intent” is
    necessarily established. Thus, rather than allowing the finder-of-fact to weigh various
    evidentiary clues of intent and arrive at an independent conclusion, this administrative
    regulation stacks the deck against the seller. For example, say an organic farmer makes
    clear to a seller that he is purchasing an adjuvant solely to aid in application of an organic
    foliar fertilizer. The farmer, a longtime client of the seller, has never used pesticides and
    plans never to do so. Yet, somewhere on the adjuvant’s label there is a notation that the
    adjuvant could be used to aid in application of fertilizers or pesticides. In that
    circumstance, Regulation 6145, subdivision (a)(1) would require a finding the adjuvant
    was “intended to be used” as an aid to application of a pesticide even though neither the
    seller nor the buyer had any such intent.
    In sum, the circumstances listed in Regulation 6145, subdivision (a)(1) should be
    subsidiary factors in discerning the ultimate issue of intent, not independently-sufficient
    proxies for intent. As currently written, the regulation hinders fact-finders and makes it
    unduly difficult for sellers to rebut the issue of intent. It should be reevaluated by the
    Department of Pesticide Regulation or addressed by the Legislature.
    II.    Permitting the Classification of a Substance as a Pesticide to Turn on Statements
    in Marketing Materials and Websites is Questionable
    One of the factors in Regulation 6145 concerns representations by the seller.
    (Regulation 6145, subd. (a).) The provision provides that a seller is deemed to have
    intended a substance to be used as a pesticide if the seller “claims, states, or implies, by
    2.
    labeling or otherwise” that the substance can or should be used as a pesticide or can be
    used to manufacture a pesticide. (Ibid.) Indeed, this factor plays a central role in our
    holding today. Yet, the relevance of marketing materials and website descriptions in
    classifying a substance as a pesticide under the statute is questionable.2 Because of their
    chemical properties, pesticides can pose threats to the safety of drinking water,
    farmworkers, farming families, and schoolchildren. (See, e.g., §§ 12980, 13141, 13182.)
    But a pesticide’s chemical properties are not changed by the marketing materials that
    accompany them. It is peculiar, then, that the definition of pesticide can turn on whether
    marketing materials suggests it can or should be used in a particular manner.
    For example, if Caltec had not indicated that Greenfeed is “compatible” with
    pesticides and can be a “carrier” for pesticides, then Greenfeed would arguably not be
    considered a pesticide. Yet, whether Greenfeed poses a threat to human health is not
    impacted by its marketing materials.
    Or, consider a seller who incorrectly believes a substance has pesticidal effects.
    The substance’s labeling would result in a pesticide classification, even if it has no such
    qualities and is entirely harmless.
    Unmooring the definition of a pesticide from a substance’s chemical properties
    would not seem to further the goal of protecting public health or the environment.
    III.      It is Unclear Why Non-Toxic Adjuvants are Regulated as Pesticides
    Adjuvants can be used in a variety of ways, not just pesticide application.
    (Application of Lemin (
    51 C.C.P.A. 942
    ) 
    326 F.2d 437
    , 944–945.) Some adjuvants are
    labeled as multipurpose. Under current regulations, if just one of those purposes is to aid
    in the application of a pesticide, then the adjuvant itself is considered a pesticide. (See
    § 12758; Regulation 6145, subd. (a).) This is true even if the adjuvant has no “toxic
    2
    Such materials are—and should remain—relevant to other issues, such as
    whether the seller has “misbranded” the substance. ( 12881, et seq.)
    3.
    properties of its own.” (§ 12758.) It is unclear what government interest is furthered by
    regulating nontoxic adjuvants as pesticides. In contrast, the federal definition of pesticide
    in title 7 United States Code section 136(u) does not expressly include adjuvants. The
    Legislature may wish to consider reexamining whether nontoxic adjuvants should be
    removed from the definition of pesticide, consistent with the federal statute.
    With these observations, I concur in the judgment.
