Pesticide Registration

Pesticide Application

In California, pesticides are registered for use by the Department of Pesticide Regulation. As part of the California registration process, data regarding the efficacy and safety of pesticides is reviewed by the Pesticide Registration and Evaluation Committee (PREC) which can recommend restrictions to reduce or eliminate potential problems. As the custodian of fish and wildlife in California, CDFW serves on the PREC. This allows CDFW to review new pesticide uses and to request reevaluation of existing pesticide uses when unacceptable hazards to fish and wildlife have been demonstrated.
