This regulation establishes time-limited tolerances for combined residues of dinotefuran, [ N -methyl- N '-nitro- N" - ((tetrahydro-3-furanyl)methyl)guanidine] and its metabolites DN [1- methyl-3-(tetrahydro-3-furylmethyl)guanidine] and UF [1-methyl-3- (tetrahydro-3-furylmethyl)urea], expressed as dinotefuran in or on rice, grain. 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 rice. This regulation establishes a maximum permissible level for residues of dinotefuran in this food commodity. The time-limited tolerance expires and is revoked on December 31, 2009.
