Pesticides and Fertilizers: Certification and Licensing

​​​About​​

The Bureau of Agrichemical Management regulates:

  • Manufacturing, sale, and use of pesticides in Wisconsin
  • Manufacturing and sale of fertilizers, and soil and plant additives in Wisconsin

The bureau certifies pesticide applicators after they pass examinations, which then makes them eligible for licensing. The bureau also licenses businesses and registers pesticide products. In the case of fertilizers and soil and plant additives, the bureau licenses businesses.
