Commercial Pesticide Testing
Commercial Pesticide Applicator Testing

Pesticide applicators may not commercially apply any pesticide until they receive a pesticide license and identification card. Minnesota law requires commercial applicators to carry a valid license identification card with them whenever applying general or restricted-use pesticides. The applicator license and card will be issued when the required exams have been passed and all other licensing requirements have been met.

Prior to testing you must apply for a license with the MN Department of Ag. For information, visit:                          

There is an option to apply online with a credit card to pay license fee; or you can print off the license application form to fill in and return to the MN Department of Ag along with your payment using the address on the form. If you have questions about applying, please call the Department of Ag at 651-201-6615.

When confirmation of application and payment is verified, you may schedule a testing time with Planning & Zoning by calling 507-238-3242.
