Why Massachusetts restricts these products
MDAR breakdown — the three core categories MDAR restricts on.Counts are the Massachusetts records under each category — select one to filter the database to those records. Massachusetts entries also appear under other restriction bases, filterable in the database below.

EPA Federal = nationwide restriction. Massachusetts = additional state restriction by MDAR. A product may appear in both lists. Restriction status may differ by jurisdiction and publication date.
EPA's Restricted Use Products report does not publish a per-product restriction reason, so federally restricted records show “Not published by EPA” in place of a basis. Those products are classified as restricted use under the criteria in 40 CFR 152.170; see also the EPA Restricted Use Products Report. The basis filter therefore returns Massachusetts records only.
Active ingredients are published by EPA only, so filtering by active ingredient returns records carried on the federal list. Export CSV downloads the rows currently matching your search and filters, in the order shown.

Classification, licensing and how this list is maintained.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.
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.
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.
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.
About this tool
The Restricted Use Pesticide Tracker combines EPA federal and Massachusetts Department of Agricultural Resources (MDAR) state restricted use pesticide lists into one searchable public database.
Pest control operators, regulators, agricultural professionals and researchers can search product names, EPA registration numbers, active ingredients and companies in one place — without cross-referencing separate agency PDFs.
Data is parsed from official source documents and checked daily for changes. Always verify against the original source publications before making compliance or regulatory decisions. Maintained by PESTalytix LLC in Sterling, Massachusetts.
