ExploreAbout this exam
The Ohio Pesticide Applicator credential is administered by the Ohio Department of Agriculture's Division of Plant Health, Pesticide Regulation program. Ohio issues two applicator license types: a Private Pesticide Applicator License, for people applying restricted-use pesticides to their own or their employer's property, and a Commercial Pesticide Applicator License, required for anyone applying pesticides for hire, soliciting application services, or performing wood-destroying insect inspections. A separate Pesticide Business License and Certificate of Insurance apply to for-hire operations, and restricted-use pesticide dealers must be licensed and inspected. Ohio defines a pesticide broadly: any substance intended to prevent, destroy, repel, or mitigate a pest, or used as a plant regulator, defoliant, or desiccant. The exam tests four connected areas: licensing and business requirements, restricted-use pesticide rules and dealer sales records, product registration and distribution, and application methods including aerial and drone (UAS) work with recordkeeping. Preparation centers on the ODA Pesticide Regulation pages, the Ohio Administrative Code pesticide rules, current product labels, and the Pesticide Safety Education Program run by OSU Extension, which offers manuals, new-applicator workshops, and recertification conferences. Because fees, record-retention rules, and certification standards change, study current ODA materials rather than older handbooks.
What you'll study
About OH Pesticide Applicator preparation
Who needs an Ohio Commercial Pesticide Applicator License instead of a Private license?
A Commercial license covers anyone applying pesticides for hire, soliciting pesticide application services, or performing wood-destroying insect inspections, even when no treatment is planned. Private licenses cover restricted-use pesticide use on your own or your employer's property. Aerial and drone applications require the Commercial license with category C-1, Aerial Application; private licenses do not permit aerial work.
What license and insurance do I need if I apply pesticides for other people?
If you apply to another person's property for hire, Ohio requires a Pesticide Business License plus a Certificate of Insurance in addition to your applicator license. The Pesticide Business License also applies to soliciting application services and to WDI inspections. Note that the former Registered Location license type was eliminated effective October 1, 2025 and converted to the Pesticide Business license.
What are the current pesticide product registration fees?
Effective October 1, 2025, the registration fee for pesticide products distributed in Ohio is $250.00 per product, and registration renewals filed after the deadline carry a $125.00 per-product penalty. Each product must be registered, and dealer locations distributing these products must be properly licensed and inspected.
Do Ohio restricted-use pesticide dealers still file annual RUP sales reports?
No. Pesticide dealers are no longer required to submit annual Restricted-Use Pesticide Sales Reports to ODA. Dealers must still keep a RUP Sales Record at the business location for at least 3 years, available for ODA inspectors on site. Records include the applicator's name and license number, use categories, purchaser name, brand and EPA registration number, quantity, dealer invoice number, and sale date.
Can I apply pesticides with a drone in Ohio?
Yes, but only with a Commercial Pesticide Applicator License carrying category C-1, Aerial Application. Private Pesticide Applicator Licenses do not permit aerial applications. If the drone application is made to another person's property for hire, you also need a Pesticide Business License and Certificate of Insurance. ODA publishes a factsheet addressing common UAS questions.
What dicamba requirements apply for over-the-top products?
Three over-the-top dicamba products are state registered in Ohio for the 2026 growing season, and you must hold a Commercial or Private applicator license to apply them. Applicators must complete the registrant's mandatory training. The labels carry recordkeeping requirements, ESA/Bulletins Live 2 language, and Mitigation Menu language, and records must also follow OAC 901:5-11-10.
How should I sequence my study time across the four exam areas?
Start with regulation and licensing, since business license, dealer, and supervision rules frame everything else. Then study restricted-use pesticide requirements and dealer sales records, followed by product registration and distribution. Finish with application methods, aerial/UAS rules, and recordkeeping. Check the ODA Pesticide Regulation pages and current labels for each area, and confirm any figures against current ODA material rather than older study guides.
What changes should I watch for that could affect exam content?
Several updates are coming. New Ohio Pesticide Certification and Training requirements take effect January 1, 2027. The Legislature modified the Ohio Revised Code in March 2026 to address direct supervision of restricted-use pesticides. An updated Commercial Fumigation (10C) exam and study guide (revision 08/26) releases August 10, 2026. Golden Malrin fly bait now requires RUP labeling, with existing general-use stock purchased before 3/1/2026 usable per its directions.
Where can I get study materials and training?
ODA points applicants to the Pesticide Safety Education Program, part of OSU Extension, which provides recertification training conferences, new applicator workshops, train-the-trainer programs, and training manuals. Commercial Pesticide exam study guides are sold through OSU Extension Publishing. ODA's Pesticide Regulation pages host forms, laws and rules, online services, and program updates worth reviewing before your exam.
What is the most common way candidates lose points?
Studying from outdated material. Fees, license types, and record rules have changed recently, including the October 1, 2025 fee changes and elimination of the Registered Location license. Candidates also stumble on restricted-use pesticide supervision rules and recordkeeping details. Build answers from current ODA pages, the Ohio Administrative Code, and current product labels rather than memory or older handbooks.
