Who is responsible for registering all pesticide active ingredients used in South Carolina?

The correct choice is that the Environmental Protection Agency (EPA) is responsible for registering all pesticide active ingredients used in South Carolina and across the United States. Under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), the EPA evaluates pesticide products to ensure that they meet safety and efficacy standards before they can be marketed and used. This includes a thorough assessment of the active ingredients, which must be registered by the EPA prior to any application in the state.

While other entities like the Department of Pesticide Regulation (DPR) in South Carolina may manage the distribution and enforcement of pesticide regulations at the state level, the ultimate authority for the registration of active ingredients lies with the EPA. The USDA, on the other hand, primarily deals with agricultural practices and does not handle pesticide registration. Thus, the role of the EPA is crucial for maintaining public health and environmental protection concerning pesticide use.
