  • § 180.355 Bentazon; tolerances for residues.

    (a) General.

    (1) Tolerances are established for the combined residues of the herbicide bentazon, 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 for only the sum of bentazon (3-isopropyl(1-methylethyl)-1H-2,1,3-benzothiadiazin-4(3H)-one - 2,2-dioxide) and its 6- and 8-hydroxy metabolites in or on the following food commodities: , 6-hydroxy-3-isopropyl-1H-2,1,3-benzothiadiazin-4(3H)-one 2,2-dioxide, and 8-hydroxy-3-isopropyl-1H-2,1,3-benzothiadiazin-4(3H)-one 2,2-dioxide calculated as the stoichiometric equivalent of bentazon.
