Section 3
The majority of pesticides registered in the United States fall under FIFRA Section 3. Each pesticide registration is for a specific, labeled use of a particular formulation which is supported by research data. Before receiving EPA registration, pesticides are required to go through an extensive environmental, health and safety evaluation by the EPA. Once a pesticide has received EPA approval and registration, it can be registered in the state if there is a use for it.
