CFR 40-180.505-2013 Protection of Environment. Part180:Tolerances and exemptions for pesticide chemical residues in food. Section180.505:Emamectin;tolerances for residues.
(a) General. (1) Tolerances are established for emamectin, 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 emamectin (a mixture of a minimum of 90% 4′-epimethylamino-4′-deoxyavermectin B1a and maximum of 10% 4′-epimethylamino-4′-deoxyavermectin B1b) and its metabolites 8,9-isomer of the B1a and B1b component of the parent (8,9-ZMA), or 4′-deoxy-4′-epi-aminoavermectin B1a and 4’-deoxy-4’-epiamino-avermectin B1b; 4′-deoxy-4′-epiamino avermectin B1a (AB1a); 4′-deoxy-4′-epi-(N-formyl-N-methyl)aminoavermectin (MFB1a); and 4′-deoxy-4′- epi-(N-formyl)amino-avermectin B1a (FAB1a), calculated as the stoichiometric equivalent of emamectin.
