This regulation establishes time-limited tolerances for residues of quinoxyfen in or on vegetable, cucurbit, subgroup 9A; pumpkin; and squash, winter. 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 melons, winter squash, and pumpkins. This regulation establishes a maximum permissible level for residues of quinoxyfen in these food commodities. These tolerances will expire and are revoked on December 31, 2007.
