Which federal agency oversees pesticide use in the United States?

The Environmental Protection Agency (EPA) is the correct answer because it is the federal agency responsible for regulating the use and distribution of pesticides in the United States. The EPA's primary role includes evaluating the safety and efficacy of pesticides, ensuring they are used in a manner that protects human health and the environment. This agency establishes guidelines for pesticide labeling, conducts research, and enforces legal standards related to pesticide use.

Other agencies mentioned, such as the Food and Drug Administration (FDA) and the Department of Agriculture (USDA), have important roles within their areas of expertise, but they do not specifically oversee pesticide use. The FDA is primarily focused on food safety and pharmaceutical regulations. Similarly, the USDA manages agricultural policy, including aspects related to crop production, but it is the EPA that has the authority to regulate pesticides. Additionally, the Occupational Safety and Health Administration (OSHA) is concerned with workplace safety and health standards rather than direct regulation of pesticide use in agriculture or commercial settings.
