This regulation establishes time-limited tolerances for residues of sulfoxaflor, N-methyloxido [1-[6-(trifluoromethyl)-3- pyridinyl]ethyl] [lambda]\4\-sulfanylidene] cyanamide, including its metabolites and degradates in or on cotton, undelinted seed; cotton, gin byproducts; and cotton, hulls. This action is in response to EPA's granting of emergency exemptions under section 18 of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) authorizing use of the pesticide on cotton. This regulation establishes maximum permissible levels for residues of sulfoxaflor in or on these commodities. These time-limited tolerances expire on December 31, 2015.
