Certified commercial and noncommercial applicators and public operators:

Due to COVID-19 all commercial and noncommercial applicators and public operators with an expiring recertification date through December 31, 2020 will be granted a one (1) year recertification extension to attend a recertification program or reexamine. For a list of approved recertification programs please click here.

Certified commercial and noncommercial applicators and certified public operators will still receive their renewal card in the mail one month prior to license expiration. If your license is due for renewal, please make sure to send the license fee and signed renewal card to the Pesticide Bureau by the expiration date on your license. If you prefer to pay online, you may login to your MOPlants account and do so.

Licensed pesticide technicians will not be granted the extension for retraining credit as they still have the capability of completing 10 hours of classroom training for each category on their license.

Certified private applicators:

Individuals needing to acquire a certified private applicator license or to renew a valid certified private applicator license may obtain initial certification or recertification credit by one of two ways. Individuals may either attend a zoom teleconference training presented by a field agronomy specialist or complete a 25 question study guide, sent in the mail, if broadband or a computer is not accessible. For more information on how to schedule private applicator certification or recertification, please click here or contact your local county extension office.

If you have any questions, please call our office at 573-751-5504 or 573-751-5509. Thank you for your understanding and patience as we work through this matter!

The overall goal of the Pesticide Program is to prevent unreasonable adverse effects of pesticide use on human health and the environment while helping assure the availability of pesticides needed to maintain our quality of life. This is accomplished by licensing pesticide applicators and dealers, registering pesticides and performing inspections and investigations in the enforcement of the Missouri Pesticide Use Act and the Missouri Pesticide Registration Act.

Legal Authority

The Pesticide Program is administered through the Bureau of Pesticide Control in the Plant Industries Division. The Bureau administers the Missouri Pesticide Use Act and Administrative Rules (281.005 - 281.180 RSMo & 2 CSR 70-25) and the Missouri Pesticide Registration Act (281.210-281.310 RSMo.).

Certification & Licensing

The Missouri Pesticide Use Act establishes requirements for licensing of applicators, dealers, technicians and operators. There are also guidelines for approving applicator training programs. These programs are conducted by the University of Missouri annually. Other programs may also be available. Learn more ...

Pesticides and Water Quality Program

The Missouri Department of Agriculture, through the Pesticide Program in the Plant Industries Division, works with a variety of state and federal agencies to maintain the high quality of Missouri water. The primary effort is to prevent pesticide-related water quality issues through the education of pesticide users. Should a pesticide-related incident potentially impact water quality, program staff will investigate to determine if state and/or federal pesticide laws have been violated. Efforts may be coordinated with other agencies to determine the appropriate response.

Driftwatch and Pesticide-Sensitive Crops

The Pesticide Program administers the Missouri DriftWatch site, a voluntary, online pesticide-sensitive crop locator service to provide a place where producers of pesticide-sensitive specialty crops, including bees, can map their crop and hive locations. Pesticide applicators can use the site to find sensitive crop locations in an effort to minimize the potential for damaging pesticide drift. For more information about this service visit DriftWatch.
