OPP Issues New Guidance on Pesticide Resistance
Stating that it intends to embark on a more widespread effort to combat pest resistance to pesticides and herbicides, EPA’s Office of Pesticide Programs (OPP) has issued two Pesticide Registration Notices (PRNs), one applicable to all conventional pesticides (herbicides, fungicides, bactericides, insecticides, and acaricides) and the second applicable to herbicide-resistant weeds.
