2.1 ORC Chapter 921 & the Authority of the Ohio Department of Agriculture
Key Takeaways
- ORC Chapter 921 is the Ohio Pesticide Law and vests administration in the Director of the Ohio Department of Agriculture, who acts through the Pesticide & Fertilizer Section.
- ORC 921.01 defines the two license classes tested on the Core exam: a commercial applicator is licensed under ORC 921.06 and a private applicator under ORC 921.11.
- ORC 921.16 is the rulemaking hook that produces every OAC 901:5-11 rule, so a statute question and a rule question are usually two views of the same requirement.
- The statute separately licenses pesticide businesses (ORC 921.09), pesticide dealers (ORC 921.13), and solicitors, and requires proof of financial responsibility (ORC 921.10).
- ORC 921.12 governs examinations and renewal deadlines, including a 50 percent late penalty and mandatory re-examination if a license lapses more than 180 days.
2.1 ORC Chapter 921 & the Authority of the Ohio Department of Agriculture
FIFRA sets the national floor. Ohio Revised Code Chapter 921, the Ohio Pesticide Law, is the statute that actually licenses you, defines what you may do, and gives the state its enforcement teeth. The Commercial Core exam draws heavily from it, and most Ohio-law questions become easy once you can place a requirement in the right section.
Who Administers It
Chapter 921 assigns administration to the Director of the Ohio Department of Agriculture (ODA). Operationally, the work is done by the Pesticide & Fertilizer Section of ODA's Division of Plant Health, at 8995 East Main Street, Reynoldsburg, Ohio 43068, phone 614-728-6987. That one office handles licensing and insurance, enforcement and complaints, and product registration.
Under ORC 921.18 the director has broad powers and duties, including entering premises at reasonable times to inspect, sampling pesticides and treated materials, and investigating complaints. ORC 921.17 lets the director delegate that authority to departmental staff, which is why field inspections are conducted by ODA inspectors rather than by the director personally.

Definitions That Decide Exam Questions
ORC 921.01(K): "Commercial applicator" means an individual licensed under ORC 921.06 to apply pesticides or to conduct authorized diagnostic inspections. ORC 921.01(J): "Private applicator" means an individual licensed under ORC 921.11. Ohio has exactly these two applicator license classes - there is no separate "for hire," "not for hire," or "public applicator" license. What varies is the pesticide-use categories printed on the license.
"Competent" (921.01(L)) is defined as having passed the general examination and each applicable pesticide-use category examination for the categories in which the person works, plus any other criteria set by rule. That definition is why passing Core alone never produces a license.
"Agricultural commodity" (921.01(C)) means a plant or animal, or part of one, produced for commercial use - including by farmers, ranchers, vineyardists, plant propagators, Christmas tree growers, aquaculturists, floriculturists, orchardists, and foresters. It is the pivot for private applicator eligibility.
"Authorized diagnostic inspection" (921.01(F)) is an inspection conducted by a commercial applicator in a category in which that applicator is licensed - the statutory basis for the Category 12 wood-destroying insect inspection license.
Statute Versus Rule
ORC 921.16 directs the Director to adopt rules. Everything in OAC Chapter 901:5-11 - trained serviceperson standards, license fees and periods, financial responsibility limits, recordkeeping fields, lawn posting signs, school rules, the IPM standard, and the civil penalty schedule - exists because 921.16 authorizes it.
Two practical consequences:
- The statute states the duty; the rule states the number. ORC 921.14 says commercial applicators shall keep records; OAC 901:5-11-10 says exactly which fields and for how long. ORC 921.06 says licenses are issued for a period established by rule; OAC 901:5-11-04 says October 1 to September 30 and $35.
- Rules change faster than statutes. ODA's EPA-approved certification and training plan, approved in August 2023, is being implemented in phases through 2032, so confirm current numbers on ODA's Laws & Rules page.
Recent Statutory Changes Worth Knowing
- HB 96 (effective September 30, 2025) amended ORC 921.12 to add a $30 examination fee, eliminated the "registered location" business license type (those licensees converted to the Pesticide Business license), and raised the pesticide product registration fee to $250.
- HB 10 (effective March 20, 2026) amended ORC 921.06, 921.11, and 921.24, refining who must be licensed and the prohibited-acts list.
