Pesticide registration is the domain of the Federal Environmental Protection Agency, (EPA). Registration is intended to maximize the benefits from pesticide use while minimizing the risks to users, the food supply and the environment. Pesticide registration is a requirement of the Federal Insecticide, Fungicide and Rodenticide act, (FIFRA), which was last revised in 1996 by the Food Quality Protection Act, (FQPA). FQPA made some big changes in FIFRA, revising the law from a risk/benefit approach to a de minimis risk, (meaning to minimize risks to persons from the food supply) process for establishing tolerances for pesticides in food and for mitigating risks from registered pesticides. One of the biggest tasks assigned to EPA was to reregister all pesticide active ingredients and review their uses within 10 years.
