According to FIFRA, what is primarily regulated?

The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) primarily regulates the sale and use of pesticides in the United States. This means that FIFRA establishes the framework for the approval, distribution, and labeling of pesticides to ensure they are safe for use and effective for pest control. The regulation covers aspects such as registration processes for pesticides before they can be sold and the standards that must be met regarding their safety and efficacy.

The focus on the sale and use encompasses the need for proper labeling, determined usage guidelines, and ensuring that the products do not pose undue risks to human health or the environment. This aspect of FIFRA is critical in maintaining safety standards while allowing agricultural and residential pest control products to be available on the market.

While the other choices touch upon related areas, they do not reflect the primary focus of FIFRA. For instance, FIFRA does not directly regulate the geographical distribution of pesticides, nor does it address the marketing of agricultural products or the application of fertilizers, which are governed by various other regulations and acts.
