This regulation establishes tolerances for combined residues of flonicamid and its metabolites TFNA, TFNA-AM, and TFNG in or on Brassica, leafy greens, subgroup 5B; hop, dried cones; okra; radish, tops; turnip, greens; vegetable, root, except sugar beet, subgroup 1B; and vegetable, tuberous and corm, subgroup 1C. It also increases established tolerances for combined residues of flonicamid and its metabolites TFNA and TFNA-AM in or on cattle, fat; cattle, meat; egg; goat, fat; goat, meat; horse, fat; horse, meat; milk; poultry, fat; poultry, meat; poultry, meat byproducts; sheep, fat; and sheep, meat. Interregional Research Project Number 4 (IR-4) requested these tolerances under the Federal Food, Drug, and Cosmetic Act (FFDCA). This regulation also removes existing tolerances for flonicamid and its metabolites on mustard greens and potatoes which are superseded by the new tolerances on "Brassica, leafy greens, subgroup 5B" and "vegetable, tuberous and corm, subgroup 1C," respectively.
