40 CFR 180.345: Ethofumesate; tolerances for residues.

(a) General. Tolerance are established for residues of the herbicide ethofumesate, 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 ethofumesate, 2-ethoxy-2,3-dihydro-3,3-dimethyl-5-benzofuranyl methanesulfonate, and its metabolites 2-hydroxy-2,3-dihydro-3,3-dimethyl-5-benzofuranyl methanesulfonate, and 2,3-dihydro-3,3-dimethyl-2-oxo-5-benzofuranylmethanesulfonate, calculated as the stoichiometric equivalent of ethofumesate, in or on the following food commodities.

(c) Tolerances with regional registrations. Tolerances with a regional registration, as defined in § 180.1(l) are established for residues of the herbicide ethofumesate, including its metabolites and degradates, in or on the commodities in the table below. Compliance with the tolerance levels specified is to be determined by measuring only the sum of ethofumesate, 2-ethoxy-2,3-dihydro-3,3-dimethyl-5-benzofuranyl methanesulfonate, and its metabolites 2-hydroxy-2,3-dihydro-3,3-dimethyl-5-benzofuranyl methanesulfonate, and 2,3-dihydro-3,3-dimethyl-2-oxo-5-benzofuranylmethanesulfonate, calculated as the stoichiometric equivalent of ethofumesate, in or on the raw agricultural commodities.

(d) Indirect or inadvertent residues. Tolerances are established for the combined indirect or inadvertent residues of the herbicide ethofumesate, including its metabolites and degradates, in or on the commodities in Table 3 to this paragraph (d). Compliance with the tolerance levels specified in Table 3 to this paragraph (d) is to be determined by measuring only the sum of ethofumesate, 2-ethoxy-2,3-dihydro-3,3-dimethyl-5-benzofuranyl methanesulfonate, and its metabolites 2-hydroxy-2,3-dihydro-3,3-dimethyl-5-benzofuranyl methanesulfonate, and 2,3-dihydro-3,3-dimethyl-2-oxo-5-benzofuranylmethanesulfonate, calculated as the stoichiometric equivalent of ethofumesate, in or on the commodity.
