This regulation establishes time-limited tolerances for combined residues of hexythiazox in or on corn, sweet, plus cobs with husks removed (K+CWHR); corn, sweet, forage; and corn, sweet, stover. This action is in response to EPA's granting of an emergency exemption under section 18 of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) authorizing use of the pesticide on sweet corn grown for seed. This regulation establishes a maximum permissible level for residues of hexythiazox in these food . The time-limited tolerances expire and are revoked on December 31, 2012.
