Pesticide Registration
The Pesticide Registration Branch is responsible for product registration and coordinates the required evaluation process among DPR branches and other state agencies. A pesticide must be registered (licensed) with the state before it can be used, possessed, or offered for sale in California. The Branch serves as primary liaison to registrants. It prepares public notices and corresponds with registrants regarding data requirements, determinations of the health effects of pesticides, and final actions on registrations. Branch scientists share data review responsibilities with staff scientists in other branches. The Branch also manages all data received, oversees call-ins of data on environmental fate and acute and chronic toxicology, maintains label files and the pesticide data library, and provides information on registered pesticides and label instructions to pesticide enforcement agencies and the public.
