Final answer:
The regulations for pest control and pesticide use in California are part of the California Code of Regulations, which go beyond the federal FIFRA and are tailored to the state's specific needs.
Step-by-step explanation:
Regulations pertaining to pest control and pesticide use in California fall under C. The California Code of Regulations. These state-specific regulations are designed to complement and sometimes go beyond the federal regulations. While the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) administers the registration of all pesticides in the United States through the Environmental Protection Agency (EPA), each state has the authority to impose additional regulations. California, known for its stringent environmental laws, has additional rules that are tailored to the state's unique ecological conditions and agricultural needs, and these are codified in the California Code of Regulations.
