§ 180.713 - Tiafenacil; tolerances for residues.

(a) General. (1) Tolerances are established for residues of the herbicide tiafenacil, including its metabolites and degradates, in or on the commodities in the table below. Compliance with the tolerance levels specified below is to be determined by measuring only tiafenacil, methyl N-[2-[[2-chloro-5-[3,6-dihydro-3-methyl-2,6-dioxo-4-(trifluoromethyl)-1(2H)-pyrimidinyl]-4-fluorophenyl]thio]-1-oxopropyl]-β-alaninate, in or on the following commodities:

Table 1 to Paragraph (a)(1)

Commodity	Parts per million	Barley subgroup 15-22B	0.01	Corn, field, grain	0.01	Corn, pop, grain	0.01	Cottonseed subgroup 20C	0.3	Fruit, citrus, group 10-10	0.01	Fruit, pome, group 11-10	0.01	Fruit, stone, group 12-12	0.01	Grain sorghum and millet subgroup 15-22E	0.01	Grape	0.01	Nut, tree, group 14-12	0.01	Peanut	0.01	Rapeseed subgroup 20A	0.15	Soybean, seed	0.01	Sweet corn subgroup 15-22D	0.01	Vegetable, legume, pulse, bean, dried shelled, except soybean, subgroup 6-22E	0.01	Vegetable, legume, pulse, pea, dried shelled, subgroup 6-22F	0.03	Wheat, grain	0.01

(2) Tolerances are established for residues of the herbicide tiafenacil, including its metabolites and degradates, in or on the commodities in the table below. Compliance with the tolerance levels specified below is to be determined by measuring only the sum of tiafenacil, methyl N-[2-[[2-chloro-5-[3,6-dihydro-3-methyl-2,6-dioxo-4-(trifluoromethyl)-1(2H)-pyrimidinyl]-4-fluorophenyl]thio]-1-oxopropyl]-β-alaninate and its metabolites 2-(2-chloro-4-fluoro-5-(3-methyl-2,6-dioxo-4-(trifluoromethyl)-2,3-dihydropyrimidin-1(6H)-yl)phenylsulfinyl)propanoic acid and 2-(2-chloro-5-(2,6-dioxo-4-(trifluoromethyl)-2,3-dihydropyrimidin-1(6H)-yl)-4-fluorophenylsulfinyl)propanoic acid, calculated as the stoichiometric equivalent of tiafenacil, in or on the following commodities:
