What is the full name and acronym of the federal agency that regulates pesticides?

The federal agency that regulates pesticides is the Environmental Protection Agency, commonly known by its acronym, EPA. The EPA is responsible for ensuring that pesticides are safe for users and the environment, thereby overseeing their registration, distribution, and usage. This regulatory body evaluates the safety and effectiveness of pesticides before they can be sold and used in the United States.

The other options presented refer to different organizations or programs that have roles related to agriculture or pesticide use but do not serve as the primary regulatory agency for pesticides at the federal level. For example, the U.S. Department of Agriculture (USDA) pertains more broadly to agricultural programs and policies, while the Office of Pesticide Programs (OPP) operates within the EPA specifically to focus on pesticide regulation. The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) is legislation governing pesticide regulation, rather than an agency itself.
