This regulation establishes a temporary exemption from the requirement of a tolerance for residues of the spinach defensin proteins SoD2, SoD2*, SoD7, and SoD8 in or on citrus when used as plant-incorporated-protectants in accordance with the terms of Experimental Use Permit (EUP) No. 88232-EUP-1. Southern Gardens Citrus Nursery, LLC, 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 spinach defensin proteins SoD2, SoD2*, SoD7, and SoD8. The temporary tolerance exemption expires on May 31, 2021.
