What is the full name and acronym of the federal agency mandated to regulate pesticides?

The federal agency that is mandated to regulate pesticides is the Environmental Protection Agency, abbreviated as EPA. This agency was established to ensure the protection of human health and the environment, and it plays a crucial role in overseeing the registration, distribution, sale, and use of pesticides in the United States. Under the authority of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), the EPA evaluates the safety and effectiveness of pesticides before they can be marketed.

The other options listed are important entities or acts in the context of pesticide regulation, but they do not function as the regulatory agency themselves. For instance, FIFRA provides the legal framework under which the EPA operates, but it is not a standalone agency. The USDA, while involved in agricultural practices and policies, does not specifically regulate pesticides. Similarly, the Pesticide Management Agency, while it may exist in some form, is not the primary federal agency responsible for this regulation. Thus, the correct answer highlights the essential role of the EPA in navigating the complexities of pesticide regulation.
