Pesticide Registration Notices
Pesticide registration (PR) notices are issued by EPA to inform pesticide registrants and other interested persons about important policies, procedures, and regulatory decisions. PR notices are interpretive tools that explain EPA's position on an issue and the rationale for it. They cannot be cited as legal requirements; however, they are subject to lengthy public comment periods and rigorous EPA review, and should be followed unless there is a clear reason not to. A PR Notice is not just guidance; it is EPA's preferred policy.
