This regulation establishes tolerances for combined residues of thiamethoxam (3-[(2-chloro-5-thiazolyl)methyl]tetrahydro-5-methyl-N- nitro-4H-1,3,5-oxadiazin-4-imine) and its metabolite CGA-322704, [N-(2- chloro-thiazol-5-ylmethyl)-N'-methyl-N'-nitro-guanidine, calculated as the stoichiometric equivalent of thiamethoxam, in or on: avocado; berry, low growing, subgroup 13-07G, except cranberry; black sapote; bushberry subgroup 13-07B, except lingonberry and blueberry, lowbush; caneberry subgroup 13-07A; canistel; fruit, small, vine climbing, subgroup 13-07F, except fuzzy kiwifruit; mamey sapote; mango; papaya; rice, grain; sapodilla; star apple; and vegetable, root, subgroup 1A. Interregional Research Project Number 4 (IR-4) and Syngenta Crop Protection, Inc., requested these tolerances under the Federal Food, Drug, and Cosmetic Act (FFDCA). In addition, this regulation amends existing tolerances for combined residues of thiamethoxam and its metabolite CGA-322704 in or on: cattle, meat byproducts; goat, meat byproducts; horse, meat byproducts; and sheep, meat byproducts. Syngenta Crop Protection, Inc., requested these amended tolerances under FFDCA.
