§ 180.596 Fosthiazate; tolerances for residues.

(a) General. A tolerance is established for residues of the insecticide fosthiazate, including its metabolites and degradates, in or on the commodity in the table in this paragraph. Compliance with the tolerance level specified in this paragraph is to be determined by measuring only the sum of fosthiazate, O-ethyl S-(1-methylpropyl)(2-oxo-3-thiazolidinyl)phosphonothioate, and its metabolite, O-ethyl S-(1-methylpropyl)(2-(methylsulfonyl)ethyl)phosphoramidothioate, calculated as the stoichiometric equivalent of fosthiazate, in or on the commodity.
