This regulation establishes time-limited tolerances for residues of fluridone in or on cotton. 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 cotton. This regulation establishes a maximum permissible level for residues of fluridone in or on cotton commodities. The time-limited tolerances expire on December 31, 2014.
