3.1 Oklahoma Combined Pesticide Law and ODAFF Authority

Why the Combined Pesticide Law Is a Core Exam Topic

Federal Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) rules still apply in Oklahoma. They do not replace the Oklahoma Combined Pesticide Law and Rules. Title 2 of the Oklahoma Statutes, § 3-81 through § 3-86, is the statute. Oklahoma Administrative Code (OAC) 35:30-17 is the Board's implementing rule. Together they cover agricultural spraying, grain-bin fumigation, urban structural pest control, golf-course programs, right-of-way work, and product registration. The Oklahoma Department of Agriculture, Food, and Forestry (ODAFF) Consumer Protection Services Division runs the program from 2800 N. Lincoln Blvd., Oklahoma City, OK 73105.

This OpenExamPrep chapter is independent study material on those Oklahoma requirements. It is not an ODAFF publication and does not claim ODAFF review, partnership, or official approval. When a fact changes, the live page at https://ag.ok.gov/pesticides/ and the current Combined Pesticide Manual control. The manual ODAFF posts today is the September 2025 edition, carrying Title 2, Oklahoma Statutes, §§ 3-81 through 3-86 and OAC 35:30-17-1 through 35:30-17-107, as amended August 11, 2024. Every ODAFF compilation is stamped unofficial copy; that stamp does not make the 2025 file optional reading, and it does not rescue a 2022 or 2024 PDF that is still circulating. Use the newest ODAFF-posted edition, not a blog recap.

Core exam items on this topic fail people who treat a certification card as a hunting license for hire. The card proves you passed written (and, where required, practical) standards. It does not, by itself, let you spray lawns in Edmond, pretreat a slab in Tulsa, or post a Facebook ad that says "OKC termite pro."

Who Administers the Law

2 O.S. § 3-85 assigns administration and enforcement to the State Board of Agriculture. The Board promulgates rules for application, sale, registration, contracts, recordkeeping, licensing, dealer permits, certification, recertification, storage, and disposal. It may inspect work, records, and contracts. It may sample pesticide materials. It is also directed, to the extent practical, to keep Oklahoma requirements uniform with FIFRA. No city, town, county, or other political subdivision may adopt or keep a pesticide sale-or-use ordinance that is more stringent than the Board's rules, including registration, notification, posting, advertising, applicator training, storage, transportation, disposal, or product composition. A Norman city inspector cannot invent a stricter posting rule that displaces ODAFF.

Day-to-day work sits in Consumer Protection Services (CPS). ODAFF's public program page states that CPS oversees licensing and certification, continuing education of applicators, and investigation of complaints alleging substandard or fraudulent work, including unlicensed companies and internally generated cases. Typical complaint subjects are termite treatments, drift from lawns or crops, right-of-way applications, and agricultural applications. CPS also handles product registration through Kelly Registration Systems, restricted-use dealer permits, and pesticide-producing establishment permits.

OSU Extension Pesticide Safety Education (Pesticide Coordinator, 127 Noble Research Center, Stillwater, OK 74078-0285, (405) 744-5531) educates. It posts CEU meeting schedules, reviews proposed CEU programs with the Department, and sells study packets through OSU Central Mailing Service. OSU does not issue applicator licenses, does not suspend certificates, and does not assess Combined Pesticide Law penalties. If a candidate confuses "I took the OSU class" with "I am licensed," that candidate is not ready for the law items.

Who Must Be Certified and Who Must Be Licensed

ODAFF's licensing narrative is the exam's starting sentence: the use of pesticides in Oklahoma is governed by the Oklahoma Combined Pesticide Law and Rules. Any person who applies pesticides commercially must be certified. Any company, including a one-person operation, must be licensed for the type of work being done. Noncommercial operations — golf courses, municipal parks crews, university grounds, and other government agencies — must be licensed, and their applicators must be certified, in order to legally use restricted-use pesticides.

Commercial application on the ODAFF page means advertising of services, recommendation for use, preparation for application, and the physical act of applying pesticide for hire or compensation. A consultant who makes a pesticide recommendation for hire or compensation, but does not purchase or apply the pesticide, still needs a consultant license in the category of the recommendation (OAC 35:30-17-2). A big-box sales clerk who is not paid extra for a product suggestion, or an architect who tells a client to hire a licensed pretreat company and is not paid for that remark, is in the rule's incidental-recommendation exemption — that is not a loophole for a side-hustle "pest advisor" on Craigslist.

Private applicators are farmers, ranchers, and growers who use or supervise RUPs to produce an agricultural commodity on property they own or rent (or that their employer owns or rents). A private license does not authorize commercial or noncommercial application, and it does not authorize purchase or use of RUPs in, on, or around a residence. Showing the private card may be necessary to buy an RUP at a permitted dealer.

Service technicians apply pesticide or employ a device while employed by a licensed commercial or noncommercial applicator, but they are not the certified applicator. ODAFF states that a service technician or certified applicator shall be present at each application performed. Service-technician identification is issued in the name of the licensed entity and must be returned to the Board when employment ends (2 O.S. § 3-82(B)(2)).

Certificate Versus License

After exams are passed, ODAFF issues a certification card. The Department's own sentence is the one to memorize: this certification card is not a license to do pesticide applicator work. A pesticide applicator license must still be obtained by any certified applicator who wants to do commercial, noncommercial, or consultant work, or it must be obtained by that person's employer.

2 O.S. § 3-82(B)(1) adds the operational rule: a license is issued only after satisfactory completion of certification standards by the person who will be the certified applicator under the license. A temporary certified applicator — someone who passed written exams but has not yet passed a required practical — does not qualify as the certified applicator for a license and may not act as a certified applicator. A certificate in a category is valid for five years unless suspended, canceled, or revoked, or until recertification is required for that category. Recertification itself is taught in Section 3.4; the point here is that passing PSI last Tuesday is not the same as hanging a license on a truck.

2 O.S. § 3-82(A): Unlawful to Act Without a Valid License

2 O.S. § 3-82(A)(1) is the advertising-and-identity rule. It is unlawful for any person to act, operate, or do business or advertise as a commercial, noncommercial, certified applicator, temporary certified applicator, service technician, or private applicator unless that person has obtained a valid applicator's license issued by the Board for the category of pesticide application in which the person is engaged, unless the person is applying to his or her own property. A valid 7a (General Pest) license does not legalize a 7b (Structural Pest) pretreat. A valid private applicator license does not legalize a custom spray on a neighbor's wheat for cash.

Other 3-82 identity rules that show up as traps:

• Each business location requires a separate license and a separate certified applicator, except that a certified applicator for a noncommercial business location may also serve as the certified applicator for one commercial business location (§ 3-82(A)(4)).
• A license shall not be issued for any applicant or representative who has only temporary certification (§ 3-82(A)(5)).
• An aerial license also requires Federal Aviation Administration documents showing the person is qualified to operate or supervise the aircraft (§ 3-82(A)(3)).

2 O.S. § 3-86: Prohibited Acts (Learn the Conduct, Not a Made-Up Fine Menu)

§ 3-86(A) lists conduct that can support suspension, cancellation, revocation, or refusal to issue or reissue a license, certificate, or identification after notice and an opportunity to be heard. Teach the concepts, not a blog's invented first-offense chart. High-yield examples from the current statute include: misrepresentation or failure to perform a contract; negligent methods or pesticides; operating so that pesticide drifts off-target; use inconsistent with labeling unless the Board gave prior written approval; refusing true information to the Board; an inaccurate, misleading, or fraudulent wood infestation report; failing to keep complete records; advertising or offering to perform in a category for which no license is held, or under a name for which no license is held; failing to explain in a signed contract how work fails to meet minimum standards; falsely claiming government recommendation or inspection; acting as an applicator, certified applicator, service technician, or private applicator without the matching credential; failing to correct substandard work within twenty (20) calendar days of written notice unless the Board grants a written extension; and failing to comply with the Worker Protection Standard in 40 CFR 170 or with a citation, stop-work, or stop-sale order.

§ 3-86(B) and (D) set the statutory range after the required process: a misdemeanor punishable by a fine of not less than $100 and not more than $10,000, jail of not less than 30 days and not more than one year, or both; and, after notice and hearing under the Administrative Procedures Act, an administrative penalty of not less than $100 and not more than $10,000 for each violation. Do not memorize a revoked internal first-violation table from an old Board packet as if it were current law. If an item asks for an amount, the statute's range is the citable figure.

Scenario: the Norman golf-course spray tech

A municipal golf course in Norman keeps a shed of RUPs for fairway disease and applies them with its own staff. Staff passed Core and Category 3a. The city never took out a noncommercial license. That is not "government so FIFRA is enough." ODAFF's program statement is that golf courses and government agencies must be licensed and applicators certified to legally use RUPs.

Scenario: the unlicensed Facebook pretreat

A person in Midwest City posts "cheap termite pretreat, certified, cash." He has a certification card from a prior employer and no current company license in 7b. § 3-82(A) and § 3-86(A)(9) and (15) treat acting, operating, doing business, or advertising without a valid license in that category as unlawful. CPS investigates unlicensed work; OSU's class roster is not a defense.
