Enforcement Authority

Back to Pesticide Use Enforcement

The Department of Pesticide Regulation (DPR) oversees a multi-tiered enforcement program. The U.S. Environmental Protection Agency (U.S. EPA) enacts laws covering minimum pesticide requirements that are enforced at the State and local (county) levels through cooperative agreements. Over the years, the California Legislature has passed more stringent laws covering pesticide registration, licensing, the sale and use of pesticides, and worker protection.

DPR has primary responsibility to enforce pesticide laws and regulations in California. The Enforcement Branch oversees compliance with pesticide use requirements, has overall responsibility for pesticide incident investigations, administers the nation's largest state monitoring program for analyzing domestic and imported produce for pesticide residues, and ensures compliance with pesticide product registration and labeling requirements.

County Agricultural Commissioners (CACs) enforce federal and state pesticide laws and regulations at the local level. CACs issue site-specific local permits for the use of restricted materials, conduct on-site application inspections, administer full pesticide use reporting, conduct worker safety inspections, and investigate pesticide incidents.
