This regulation establishes tolerances for combined residues of tefluthrin and its metabolite in or on corn, grain, field and pop; corn, forage and fodder, field, pop and sweet; and corn, fresh (including sweet K and corn with husk removed (CWHR)) at 0.06 parts per million (ppm). It also removes time limitations for tolerances for residues of tefluthrin on the same commodities that expire on November 15, 1997. Zeneca Ag Products requested these tolerances under the Federal Food, Drug, and Cosmetic Act (FFDCA), as amended by the Food Quality Protection Act of 1996 (Pub. L. 104-170).
