Category H: Seed Treatment

Treated seed that is dark pink.

Learn about applying insecticides and fungicides to seeds. The audience is commercial and noncommercial pesticide applicators. Category H recertification workshops also include recertification credit for Category A (core), and some also include Category C.

Who must attend a Category H recertification workshop?

Minnesota pesticide applicators licensed in Categories A and H who last attended a workshop in 2017 need to attend an MDA approved recertification workshop. New pesticide applicators (licensed for the first time in 2019) need to attend a workshop, too. Attendance at an approved recertification workshop once every two years fulfills the recertification requirement in Categories A and H by licensed commercial and noncommercial pesticide applicators.

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


License renewal is required every year and follows recertification. Attending a 2020 recertification workshop for Category H enables pesticide applicators to renew their license in 2020, 2021 and 2022. If an applicator does not attend a 2020 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 2020 for Category H, you'll be required to attend a recertification workshop or take the exam again in 2023.
