Which of the following agencies regulates pesticides in California?

The correct answer is that all of the listed agencies regulate pesticides in California. Each of these entities plays a distinct yet complementary role in pesticide regulation.

The United States Environmental Protection Agency (USEPA) is responsible for overseeing the registration of pesticides at the federal level, ensuring that they meet safety standards and are effective for their intended uses.

The California Department of Pesticide Regulation (DPR) manages the state's pesticide program, implementing and enforcing laws and regulations specific to California. This includes the registration of pesticides for use within the state, setting residue tolerances, and ensuring that pesticides are used safely and responsibly.

County Agricultural Commissioners (CACs) operate at the local level and provide enforcement of laws and regulations pertaining to pesticides within each county. They are involved in issuing permits for pesticide use, conducting inspections, and ensuring compliance with pesticide application laws.

Since all three agencies contribute to the regulation of pesticides across different levels of government, acknowledging the collaboration among them underlines the complexity and importance of pesticide management in California.
