Pesticide Regulation

General Information

The division’s Pesticide Regulation Program regulates the use and distribution of pesticides in Ohio. This section issues licenses to pesticide applicators and serves as the registrar for pesticide companies. Through routine inspections, staff members enforce the state laws and rules that govern these activities. In addition to these responsibilities, staff members conduct inspections for the U.S. Environmental Protection Agency in accordance with a cooperative agreement to ensure compliance with the Federal Insecticide, Fungicide and Rodenticide Act. The section licenses over 25,000 pesticide applicators and more than 15,000 pesticide products.

What are Pesticides?

A pesticide is any substance or mixture of substances intended for:

  • Preventing, destroying, repelling or mitigating any pest; or
  • Used as a plant regulator, defoliant, or desiccant

"Pesticide" is a general term that includes, but is not limited to, all herbicides, insecticides, rodenticides, fungicides, disinfectants, and insect repellents.

General and Restricted-use Products

Pesticides are classified as either:

  • restricted use pesticides (RUPs); or
  • general use (unclassified) pesticides

RUPs are not available for purchase or use by the general public. RUPs have the potential to cause unreasonable adverse effects to the environment and injury to applicators or bystanders without added restrictions. In Ohio, the sale and use of RUPs are limited to licensed Private or Commercial Pesticide Applicators, or someone under the direct supervision of a licensed applicator.

Ohio Specialty Crop Registry by Fieldwatch Inc

The Ohio FieldWatch Registries are voluntary crop & apiary mapping programs managed and operated by the non-profit company FieldWatch Inc. The stewardship tools allows for improved communication and collaboration between producers of specialty crops and pesticide applicators using a technology platform where producers can map their sites and provide contact information to pesticide applicators through an online mapping system.


Unmanned Aerial Vehicles

If you are wanting to apply pesticides by UAV (drone), ODA has published this helpful factsheet to answer common questions.

Certification and Training Plan

The US Environmental Protection Agency (USEPA) has finalized new federal standards for those who apply and handle restricted-use pesticides. Ohio is currently developing a new certification and training plan (C&T Plan) to meet the new rule requirements. ODA’s existing C&T Plan remains in effect until USEPA approves the proposed plan modifications, or until those plans expire on November 4, 2023, whichever is earlier.

See this page for more information

Worker Protection Standard (WPS)

On November 2015, the USEPA revised the WPS regulation strengthened elements of the existing rule to better protect workers and handlers from occupational exposure to pesticides and reduce the numbers of potentially preventable pesticide incidents and illnesses. Most of these revised WPS standards became effective in January 2018. WPS requires commercial pesticide handler employers to provide specific information and protections to workers, handlers when WPS-labeled pesticide products are used on agricultural establishments in the production of agricultural plants.    
Who is Included in WPS

Individuals who:

  • mixing, loading or apply agricultural pesticides
  • clean or repair pesticide agricultural equipment
  • assist with the application of pesticides

Trained Servicepersons

A trained serviceperson is a non-licensed commercial or private user of pesticides who works under the direct supervision of a licensed applicator. You must be a Trained Serviceperson if you commercially:
  • Apply pesticides.
  • Assist with pesticide applications.
  • Clean, repair, or maintain pesticide application equipment —such as boom sprayers, backpack sprayers, or hoppers —that may contain pesticide residues.
  • Mix, load, or transfer pesticides into application equipment.
  • Dispose of pesticides or materials with pesticides in them, such as containers.
  • Act as a flagger.

To act as a trained serviceperson, before the employee's first occupational exposure to pesticides, he or she must either:

An employer must be able to verify that the serviceperson training has been given and that it has conformed to the criteria established by ODA. Documentation needs to be kept in their personnel file while with the company and for three years after termination of employment.

  • Supervisor must have an Ohio Commercial Applicator License.
  • Licensed supervisor must demonstrate instruction and control over trained serviceperson.
  • Licensed applicator must be within 25 miles or available within 2 hours when a pesticide application is being made by the trained serviceperson.
  • Licensed applicators providing supervision must be employed by the same company or agency as the trained serviceperson


There are three types of business that are licensed by the Pesticide Program:

  • pesticide application and WDI inspection businesses;
  • pesticide application solicitors; and
  • dealers who sell restricted-use pesticide products.

Pesticide Business & Business Locations

  • A Pesticide Business is a business that applies pesticides to the property of another for hire, or solicits and takes orders to apply pesticides, or conducts diagnostic inspections for WDI in a contemplated real estate transaction. Proof of insurance is required for this license. Note: even if a WDI inspection business does not apply pesticides, it is still considered a Pesticide Business.
  • A Business Location is any additional location or branch operating in Ohio with the same name of a Pesticide Business that operates in Ohio. Proof of insurance is required for this license.
  • The license application can be found on the Forms page.

Pesticide Solicitation

  • A pesticide solicitation business license is required for a solicitation company that contracts with a licensed pesticide business in Ohio to perform applications. This license type is prohibited from making pesticide applications. There is no insurance requirement for solicitation businesses, but they must be licensed annually, from October 1 through September 30. The license application can be found on the Forms page.
  • Please note: Soliciting to do a WDI Inspection is not a Pesticide Business Activity, and does not need a Pesticide Business License nor a Solicitation License. However, the company that is actually conducting the WDI inspection must have a Pesticide Business License

Restricted Product Dealer

  • A person or facility who distributes Restricted Use Pesticides (RUP) or pesticides whose use are further restricted by the director to the ultimate user or to a commercial applicator who is employed by the pesticide dealer. A license is required for each location or outlet within the state from which the person distributes pesticides. The license application can be found on the Forms page.
  • Yearly reporting of sales is required; reports of restricted use sales for the period July 1 to June 30 are due by July 31 of each year.

Product Registration

Any pesticide product (including general use, restricted use, and minimum risk) that is distributed within the State of Ohio must first be registered with our office. The product registration period in Ohio runs from July 1 through June 30, with registrations expiring annually.

New Product (Section 3) Registrations

After US EPA has registered a pesticide product, it must also be registered in Ohio before it is legal to distribute. Separate registrations are required for each product name and alternate brand name that will be distributed in Ohio. The brand names to be registered in Ohio must be exactly the same as the brand name registered by US EPA and the same as on the product labeling.

Minimum Risk Pesticides (Section 25b)

Under Section 25(b) of FIFRA, products which meet several conditions may be exempt from EPA registration. However, these minimum risk products are required to be registered with the State of Ohio. These can be registered using the same Ohio Application for Registration of New Pesticides form as for EPA-registered products. The product label must list all active ingredients by name and percentage, and all inert ingredients must be listed by name (percentage is optional).

Enforcement & Complaints

All pesticide products distributed in Ohio are registered annually and reviewed for proper label use directions. Program inspectors regularly visit restricted pesticide dealers in Ohio to assure proper distribution. In addition, businesses that manufacture or repackage pesticides are inspected for FIFRA compliance and pesticide businesses and applicators are regularly inspected to verify proper licensing, record keeping, training and pesticide use.

Pesticide program inspectors also investigate citizen complaints involving human health, environmental damage, crop injury, personal property damage, wildlife and domestic animal poisonings, and public and private water contamination. If you suspect damage caused by pesticide misuse, please contact our office at 614-728-6987.
