Category F: Aquatic

Surface of water.

Learn about applying pesticides to aquatic systems. You will also learn about pesticide applicator licensing and certification, an update on pesticide regulatory compliance, new regulations and more. Category F recertification workshops also include recertification credit for Category A (core).

The audience is commercial and noncommercial pesticide applicators.

Who must attend a Category F Recertification Workshop?

Minnesota pesticide applicators licensed in Categories A and F who last attended a workshop in 2017 need to attend an MDA approved recertification workshop. New pesticide applicators (licensed for the first time in 2018) need to attend a workshop, too. Attendance at an approved recertification workshop once every two years fulfills the recertification requirement in Categories A and F by licensed commercial and noncommercial pesticide applicators. Some license categories require recertification more often.

When do I renew my license, attend a recertification workshop or retest?


License renewal is required every year and follows recertification. Attending a 2019 recertification workshop for Category F enables pesticide applicators to renew their license in 2019 and 2020. If an applicator does not attend a 2019 workshop in their categories as required, retesting must be completed before a license can be renewed. Then, in addition to the license application fee, retest fees are charged for each category.


If you attend a recertification workshop in 2019 for Category F, you'll be required to attend a recertification workshop or take the exam again in 2021.
