Which federal agency oversees pesticide registration in the United States?

The Environmental Protection Agency (EPA) is the federal agency responsible for overseeing pesticide registration in the United States. This role is crucial because the EPA evaluates the safety and efficacy of pesticides before they can be marketed or used. The agency reviews scientific data to ensure that pesticides will not pose unreasonable risks to human health or the environment when used according to label directions.

The EPA's responsibilities include assessing the potential impact of pesticides on non-target species, the environment, and public health, which is vital for maintaining ecological balance and protecting human health. Additionally, the EPA regulates pesticide labeling, which ensures that users are informed about the safe and effective use of these chemicals.

In contrast, the other agencies mentioned have different areas of focus. The Department of Agriculture typically deals with agricultural policies and assistance rather than pesticide registration. OSHA focuses on worker safety and health in occupational settings, while the FDA primarily oversees the safety and regulation of food and drug products, not pesticides. Thus, the EPA is the correct agency that specifically handles the registration and oversight of pesticides.
