What type of pesticide is regulated by the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)?

The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) regulates all pesticides, which encompasses a wide range of products used in various settings. This includes not only agricultural pesticides that are applied on crops to enhance agricultural productivity but also commercial pesticides used in industrial and institutional settings, and household pesticides that individuals might use in and around their homes to manage pests.

By covering all categories of pesticides, FIFRA ensures that any pesticide distributed or sold in the United States meets certain safety and effectiveness standards, regardless of its intended use. This comprehensive regulation aims to protect human health and the environment from potential hazards associated with pesticide use, thus underscoring the importance of unified regulatory oversight in maintaining safety and effectiveness across all types of pesticides.

The other options are too narrow as they only focus on specific types of pesticides, neglecting the broader regulatory scope established by FIFRA that includes all pesticide products.
