Frequently Asked Questions
ReferenceWhat is a restricted use pesticide?
A restricted use pesticide (RUP) is a product the EPA has classified as potentially harmful to the environment or applicators without additional safeguards. Only certified applicators, or people under their direct supervision, can purchase and apply RUPs. States can add products to their own restricted lists beyond the federal EPA designations.
What is the difference between federal and state restricted use pesticides?
Federal RUPs are designated by the EPA and apply across the entire United States. State RUPs are additional restrictions imposed by individual state agencies. In Massachusetts, the Department of Agricultural Resources (MDAR) maintains a State Restricted Use Products (SRUP) list that goes beyond federal requirements. A product can appear on both the federal and state lists. This tracker combines both sources into one searchable database.
Do I need a license to apply restricted use pesticides in Massachusetts?
Yes. Massachusetts requires a valid pesticide applicator license from MDAR to apply restricted use pesticides. Commercial applicators must pass category-specific exams and maintain their license through continuing education credits. Applying RUPs without proper certification violates both FIFRA (federal law) and Massachusetts state regulations.
How often does the EPA update the restricted use pesticide list?
The EPA does not follow a fixed update schedule. Changes happen when new products are registered with restricted use classification, when registrations are modified or cancelled, or during periodic regulatory reviews. Massachusetts MDAR updates its state list independently on its own timeline. This tracker checks both source publications daily and flags detected changes in the Recent Changes section above.
