This regulation establishes time-limited tolerances for residues of acibenzolar-S-methyl in or on onion, dry bulb and onion, green. 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 onion, dry bulb and onion, green. This regulation establishes a maximum permissible level for residues of acibenzolar-S-methyl in these food commodities. These tolerances will expire and are revoked on June 30, 2007.
