This regulation establishes tolerances for residues of thiencarbazone-methyl [methyl 4-[[[(4,5-dihydro-3-methoxy-4-methyl-5- oxo-1H-1,2,4-triazol-1-yl)-carbonyl]amino]sulfonyl]-5-methyl-3- thiophenecarboxylate], per se, in or on field corn, pop corn, sweet corn, and wheat; combined residues of thiencarbazone-methyl and its metabolite BYH 18636-MMT [5-methoxy-4-methyl-2,4-dihydro-3H-1,2,4- triazol-3-one], calculated as the parent compound, in or on livestock commodities; and indirect or inadvertent combined residues of thiencarbazone-methyl and its metabolite BYH 18636-MMT-glucoside [2- hexopyranosyl-5-methoxy-4-methyl-2,4-dihydro-3H-1,2,4-triazol-3-one], calculated as the parent compound, in or on soybeans. Bayer CropScience requested these tolerances under the Federal Food, Drug, and Cosmetic Act (FFDCA).
