AAPCO formed a FIFRA 25(b) workgroup in Spring 2017.

The workgroup’s mission is to facilitate the collaboration of states and industry in order to share information, provide guidance, foster label consistency, and reduce the duplication of efforts in the review and registration of Minimum Risk Pesticide products.
