S-Abscisic Acid, (S)-5-(1-hydroxy-2,6,6-trimethyl-4-oxo-1-cyclohex-2-enyl)-3-methyl-penta-(2Z,4E)-dienoic Acid; Amendment to an Exemption from the Requirement of a Tolerance

This regulation amends the current temporary exemption from the requirement of a tolerance for residues of the biochemical pesticide S-Abscisic Acid, (S)-5-(1-hydroxy-2,6,6-trimethyl-4-oxo-1- cyclohex-2-enyl)-3-methyl-penta-(2Z,4E)-dienoic Acid (ABA), to make it a permanent exemption from the requirement of a tolerance for residues of ABA in or on all food commodities when applied or used preharvest as a plant regulator. Valent Biosciences Corporation submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting that the Agency amend the existing temporary exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of S-Abscisic Acid.
