§ 180.350 - Nitrapyrin; tolerances for residues.
(a) General. Tolerances are established for residues of the nitrification inhibitor nitrapyrin, 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 nitrapyrin (2-chloro-6-(trichloromethyl) pyridine) and its 6-CPA metabolite (6-chloro-picolinic acid), calculated as the stoichiometric equivalent of nitrapyrin, in or on the commodity:
