## Abstract

This regulation establishes a 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 in or on leafy vegetables, herbs and spices, pome fruit, stone fruit, grapes and pineapples when applied/used as a plant regulator in accordance with the terms of Experimental Use Permit (EUP) 73049-EUP-7. Valent BioSciences Corporation submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting the temporary tolerance exemption. This regulation eliminates the need to establish a maximum permissible level for residues of S-Abscisic Acid, (S)-5-(1-hydroxy-2,6,6- trimethyl-4-oxo-1-cyclohex-2-enyl)-3-methyl-penta-(2Z,4E)-dienoic Acid for the uses permitted under EUP 73049-EUP-7. The temporary tolerance exemption expires on August 7, 2012.
