Specific persistence and fate of a soil active herbicide-hexazinone and implications for management

Federal pesticide regulation began officially in 1947 with the promulgation of P.L. 80-104, also known as the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). This early version was administered by the U.S. Department of Agriculture. Responsibility for administration of FIFRA was transferred to the U.S. Environmental Protection Agency (EPA) when it was created in 1970. Subsequently FIFRA was completely revised in 1972 to form the basis for our current Federal pesticide regulation policy. FIFRA, 1972 (7 USC 136 et seq.) required the registration of all pesticides marketed in the U.S. FIFRA was again amended in 1988 to require re-registration of all active ingredients with outstanding data gaps registered before 1984. The Food Quality Protection Act of 1996 (P.L. 104170) further amended FIFRA by facilitating the registration of minor use pesticides and required FIFRA coordination with activities of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 321 et seq.). It is under this backdrop of regulation that all pesticides are registered and regulated in the United States.
