Regulation Analysis: Epyrifenacil Pesticide Tolerances in the United States
The U.S. Environmental Protection Agency (EPA) has established and corrected pesticide tolerances for epyrifenacil (CASRN 353292-31-6) under the Federal Food, Drug, and Cosmetic Act (FFDCA). These tolerances define the maximum permissible residue levels of epyrifenacil in or on specified food and feed commodities. Below is a structured summary of the regulatory requirements, corrections, and compliance deadlines.
1. Established Tolerances for Epyrifenacil
The EPA’s final rule (published 30 June 2026) sets tolerances for epyrifenacil residues in the following commodities1:
- Corn, field: forage, grain, stover
- Rapeseed: seed
- Soybean: forage, hay, seed
- Wheat: forage, grain, hay, straw
These tolerances were requested by Valent U.S.A. LLC to ensure compliance with FFDCA safety standards1.
2. Correction of Inadvertent Errors
The EPA issued a corrigendum (published 28 July 2026) to correct erroneous tolerance levels initially set for:
- Corn, field: forage, stover
- Wheat: forage, hay, straw
- Soybean: forage, hay2
The corrected tolerances are now in effect as of 28 July 20262.
3. Key Regulatory Requirements and Deadlines
| Regulation | Key Requirement | Deadline/Threshold | Authority |
|---|---|---|---|
| Final Rule (30 June 2026) | Establishes tolerances for epyrifenacil residues in corn, rapeseed, soybean, and wheat1. | Effective 30 June 2026 | EPA1 |
| Corrigendum (28 July 2026) | Corrects erroneous tolerances for corn (forage, stover), wheat (forage, hay, straw), and soybean (forage, hay)2. | Effective 28 July 2026 | EPA2 |
| Objections/Hearings | Objections or requests for hearings must be submitted to EPA2. | On or before 28 September 2026 | EPA2 |
| Public Comments | Comments on the final rule may be submitted to EPA’s WTO SPS team1. | On or before 31 August 2026 | EPA (EPAWTOSPS@epa.gov)1 |
4. Compliance Obligations
- Food Safety: The tolerances ensure that epyrifenacil residues in food/feed do not exceed safe levels under FFDCA1.
- International Standards: No relevant Codex Alimentarius, OIE, or IPPC standards apply1.
- Trade Impact: The regulation affects all trading partners exporting the covered commodities to the U.S.1.
5. Submission of Comments or Objections
- Comments: Submit to EPAWTOSPS@epa.gov by 31 August 20261.
- Objections/Hearings: Submit to EPA by 28 September 20262.
Summary Answer
The EPA’s final rule (30 June 2026) establishes pesticide tolerances for epyrifenacil in corn, rapeseed, soybean, and wheat, with corrections issued via corrigendum (28 July 2026) for specific commodities2, 1. The regulation is effective immediately, with deadlines for objections (28 September 2026) and public comments (31 August 2026)2, 1. Compliance is mandatory for all entities handling these commodities, and no international standards apply1. Stakeholders must submit feedback or objections to EPA as specified2, 1.
