What agency must approve a pesticide for use before it is available in the market?

The Environmental Protection Agency (EPA) is responsible for approving pesticides for use before they can be marketed. The agency reviews scientific data and assesses the safety and effectiveness of the pesticide, ensuring that it meets federal standards for public health and environmental protection. This includes evaluating potential risks to humans, wildlife, and the environment, as well as confirming that the product performs as claimed by the manufacturer.

Other agencies, such as the Michigan Department of Agriculture, may have roles in the registration or regulation of pesticides at the state level, but the EPA is the primary federal body tasked with the initial approval process. The Department of Health Services and the Department of Natural Resources may be involved in specific assessments related to health effects or ecological impacts but do not have the authority to approve pesticides for market use.
