§ 180.505 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′-epi-methylamino-4′-deoxyavermectin B_1a and maximum of 10% 4′-epi-methylamino-4′-deoxyavermectin B_1b) and its metabolites 8,9-isomer of the B_1a and B_1b component of the parent (8,9-ZMA), or 4′-deoxy-4′-epi-amino-avermectin B_1a and 4'-deoxy-4′-epi-amino-avermectin B_1b; 4′-deoxy-4′-epi-amino avermectin B_1a (AB_1a); 4′-deoxy-4′-epi-(N-formyl-N-methyl)amino-avermectin (MFB_1a); and 4′-deoxy-4′-epi-(N-formyl)amino-avermectin B_1a (FAB_1a), calculated as the stoichiometric equivalent of emamectin.

¹ There are no U.S. registrations for use of emamectin on grape, wine.

² Emamectin benzoate has not been registered for use in the United States as of February 17, 2021.

(2) Tolerances are established for emamectin, including its metabolites and degradates, in or on the commodities in the following table. Compliance with the tolerance levels specified in the following table is to be determined by measuring only the sum of emamectin (MAB_1a + MAB_1b isomers) and the associated 8,9-Z isomers (8,9-ZB_1a and 8,9-ZB_1b).
