§ 180.420 Fluridone; tolerances for residues.
(a) General. (1) Tolerances are established for residues of the herbicide fluridone, including its metabolites and degradates, in or on the commodities in the table in this paragraph. Compliance with the tolerance levels specified in this paragraph is to be determined by measuring only the sum of fluridone, 1-methyl-3-phenyl-5-(3-(trifluoromethyl)phenyl)-4(1H)-pyridinone, and its bound residues, calculated as the stoichiometric equivalent of fluridone, in or on the commodity.
| Commodity | Parts per million |
|---|---|
| Crayfish | 0.5 |
| Fish | 0.5 |
