This regulation establishes tolerances for the residues of metconazole, including its metabolites and degradates, in or on corn, field, forage; corn, field, grain; corn, field, stover; corn, pop, grain; corn, pop, stover; corn, sweet, forage; corn, sweet, kernel plus cob with husks removed; corn, sweet, stover; cotton, undelinted seed; and cotton, gin byproducts. BASF Corporation requested these tolerances under the Federal Food, Drug, and Cosmetic Act (FFDCA). This regulation also establishes tolerances for residues of metconazole, including its metabolites and degradates, in or on canola seed, and eggs. Valent U.S.A. Corporation requested the tolerance for canola seed under the FFDCA. EPA required an additional tolerance for eggs based on findings in the studies submitted by the registrant. In addition, this action establishes time-limited tolerances for the residues of metconazole, including its metabolites and degradates, in or on sugarcane, cane at 1.6 ppm and sugarcane, molasses at 3.2 ppm, in response to the approval of crisis exemptions declared by the states of Florida and Louisiana under section 18 of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) authorizing the quarantine use of the fungicide on sugarcane to control the fungal pathogen, Puccinia kuehnii. This regulation establishes a maximum permissible level of residues in this food commodity. The time-limited tolerances expire and are revoked on December 31, 2011.
