# §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)](#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.
- (b) [Reserved]
