Which agency oversees the regulation of pesticides on a federal level?

The agency that oversees the regulation of pesticides at the federal level is the Environmental Protection Agency (EPA). The EPA is responsible for ensuring that pesticides are safe for human health and the environment before they can be marketed and used. This involves reviewing and approving pesticide labels, assessing the risks associated with pesticide use, and conducting research on their environmental impact.

The EPA's regulatory framework includes the registration process for pesticides, where companies must submit data on the safety and efficacy of their products. This is critical in protecting public health and ensuring that agricultural and non-agricultural pesticide applications do not pose undue risks to people, wildlife, or water resources.

In contrast, the Food and Drug Administration (FDA) primarily regulates the safety of food products and cosmetics, while the Department of Agriculture (USDA) focuses on policies related to farming and food supply, and the Department of Homeland Security (DHS) is concerned with national security issues. Therefore, these agencies do not have the same regulatory authority over pesticides as the EPA.
