Compliance with the tolerance levels specified in this paragraph is to be determined by measuring only the sum of pyridate, O-(6-chloro-3-phenyl-4-pyridazinyl)-S-octyl-carbonothioate, and its metabolites, 6-chloro-3-phenyl-pyridazine-4-ol and conjugates of 6-chloro-3-phenyl-pyridazine-4-ol, calculated as the stoichiometric equivalent of pyridate, in or on the commodity.
