§ 180.209 — Terbacil; Tolerances For Residues

(a) General. Tolerances are established for residues of the herbicide terbacil, including its metabolites and degradates, in or on the commodities in table 1 to this paragraph (a). Compliance with the tolerance levels specified in table 1 to this paragraph (a) is to be determined by measuring only the sum of terbacil (5-chloro-3-(1,1-dimethylethyl)-6-methyl-2,4(1H,3H)-pyrimidinedione) and its metabolites 3-tert-butyl-5-chloro-6-hydroxymethyluracil, 6-chloro-2,3-dihydro-7-hydroxymethyl 3,3-dimethyl-5H-oxazolo(3,2-a) pyrimidin-5-one, and 6-chloro-2,3-dihydro-3,3,7-trimethyl-5H-oxazolo(3,2-a) pyrimidin-5-one, calculated as the stoichiometric equivalent of terbacil, in or on the commodity.
