  - Office: Office of Pesticide Programs
- The rule exempts phosphatidylcholine (CAS Reg. No. 97281-47-5) from pesticide residue tolerance requirements when used as an inert ingredient, specifically an adjuvant or carrier, in pesticide contraceptive formulations applied to cervids, porcines, raccoons, and bovines.

### Description

This final rule establishes an exemption from the requirement for a tolerance for residues of phosphatidylcholine when used as an inert ingredient (adjuvant/carrier) in pesticide contraceptive formulations applied to cervid, porcine, raccoon, and bovine. Compliance Services International, on behalf of SpayVac-for-Wildlife, Inc., petitioned the EPA for the exemption under the Federal Food, Drug, and Cosmetic Act. The rule removes the need to establish a maximum permissible residue level when phosphatidylcholine is used in accordance with the exemption. Objections and requests for hearings must be received by December 1, 2026.
