§ 180.729 Cyclobutrifluram; tolerances for residues.
(a) General. Tolerances are established for residues of the nematicide/fungicide cyclobutrifluram, including its metabolites and degradates, in or on the plant commodities in table 1 to this paragraph (a). Compliance with the tolerance levels specified in table 1 is to be determined by measuring the sum of cyclobutrifluram (rel-N-[(1R,2R)-2-(2,4-dichlorophenyl)cyclobutyl]-2-(trifluoromethyl)-3-pyridinecarboxamide) and its metabolite 2-trifluoromethyl-nicotinamide, calculated as the stoichiometric equivalent of cyclobutrifluram in or on plant commodities.
