JEFFERSON CITY – The MDA Pesticide Program works 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.
New Pesticide Statutes and Rules went into effect Jan. 1, 2025.
The MDA website houses documents that walk through common questions regarding the changes to pesticide certification and licensing.
