## Abstract

This regulation amends and extends a temporary exemption from the requirement of a tolerance for residues of the Citrus tristeza virus expressing spinach defensin proteins 2, 7, and 8 alone or in various combinations on citrus fruit (Citrus spp., Fortunella spp., Crop Group 10-10) when applied/used as a microbial pesticide in accordance with the terms of Experimental Use Permit (EUP) No. 88232- EUP-2. Southern Gardens Citrus submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting extension of the temporary tolerance exemption. This regulation eliminates the need to establish a maximum permissible level for residues of Citrus tristeza virus expressing spinach defensin proteins 2, 7, and 8 alone or in various combinations. The temporary tolerance exemption expires on August 31, 2023.
