FIFRA (Federal Insecticide, Fungicide, and Rodenticide Act) is the law which generally controls Pesticide sale and use.

FIFRA is a United States federal law that regulates the use of pesticides to protect human health and the environment. FIFRA requires the registration of all pesticides and establishes a system of labeling, packaging, and usage requirements. Here are some examples of how FIFRA is used in the environment context:

1. Pesticide registration: FIFRA requires all pesticides to be registered with the Environmental Protection Agency (EPA) before they can be sold or distributed in the United States. The registration process includes a thorough review of the pesticide's composition, efficacy, and potential environmental and human health risks.

2. Pesticide labeling: FIFRA requires all pesticides to be labeled with specific information, including the product name, active ingredients, directions for use, and warnings about potential hazards. Pesticide labels must also include information about disposal and storage requirements.

3. Pesticide usage: FIFRA regulates the use of pesticides to ensure that they are used in a manner that protects human health and the environment. This includes establishing guidelines for application rates, application methods, and safety measures.

FIFRA is an important law in the United States that helps to protect human health and the environment from the potential harms associated with pesticide use. The EPA is responsible for enforcing FIFRA, which includes conducting inspections, investigating complaints, and issuing fines or penalties for violations.
