Commercial – Certification Categories

These are the commercial certification categories offered in the State of Wisconsin. However, if you apply pesticides to produce an agricultural commodity AND you do it on property that you or your employer owns or controls, then please click “Private Applicator” in the menu above. Otherwise, you are in the right spot.

There are 17 Commercial Applicator base categories and 3 subcategories. If you need to be certified as a pesticide applicator, you will need to get certified in the appropriate category(ies) and, if applicable, subcategory(ies).
