What the agency says

This regulation establishes an exemption from the requirement of a tolerance for residues of Citrus tristeza virus (CTV) strain T36 expressing Spinach Defensin Proteins SoD2, SoD2-1, and SoD2* in or on the food and feed commodities of citrus. Silvec Biologics, Inc submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA) requesting an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of CTV strain T36 expressing Spinach Defensin Proteins SoD2, SoD2-1, and SoD2* under FFDCA when used in accordance with this exemption.
