This regulation establishes tolerances for residues of quinoxyfen in or on multiple commodities which are identified and discussed later in this document. This regulation also deletes the established tolerances in or on grape; pepper, bell; pepper, nonbell; and strawberry as they will be superseded by crop group/subgroup tolerances established by this tolerance rule. The Interregional Research Project Number 4 (IR-4) Project Headquarters requested these tolerances under the Federal Food, Drug, and Cosmetic Act (FFDCA).
