This regulation establishes tolerances for the combined residues of spiromesifen (2-oxo-3-(2,4,6-trimethylphenyl)-1- oxaspiro[4.4]non-3-en-4-yl 3,3-dimethylbutanoate) and its enol metabolite (4-hydroxy-3-(2,4,6-trimethylphenyl)-1-oxaspiro[4.4]non-3- en-2-one), calculated as the parent compound equivalents, in or on pop corn grain and stover. Bayer CropScience requested these tolerances under the Federal Food, Drug, and Cosmetic Act (FFDCA). In addition, this regulation establishes tolerances for sweet corn, kernel, stover, and forage; and berry, lowgrowing, subgroup 13G. Interregional Research Project No. 4 (IR-4) requested these tolerances under the FFDCA. Additionally, the existing tolerance for strawberry is being deleted because it is superseded by the tolerances established for low growing berry subgroup 13-07G. Also, the tolerances for milk fat and meat byproducts of cattle, goats, horses, and sheep are being increased.In addition, this action establishes time-limited tolerances for the combined residues of spiromesifen (2-oxo-3-(2,4,6-trimethylphenyl)-1- oxaspiro[4.4]non-3-en-4-yl 3,3-dimethylbutanoate) and its enol metabolite (4-hydroxy-3-(2,4,6-trimethylphenyl)-1-oxaspiro[4.4]non-3- en-2-one), calculated as the parent compound equivalents, in or on soybean commodities in response to the approval of a specific exemption under section 18 of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) authorizing the use of spiromesifen on soybeans to control spider mites. The time-limited tolerances expire and are revoked on December 31, 2011.
