EPA Greenlights Tree Sap Goo in Your Pesticides

## Summary

The EPA just made it official: resin acids mixed with glycerol can be used in pesticides on crops without worrying about residue limits. This means farmers, food makers, and pesticide companies get a smoother ride—no more setting max residue levels for this ingredient. The rule kicks in June 18, 2026, and if anyone wants to object, they have until August 17, 2026 to speak up.

## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of resin acids, esters with glycerol (CAS Reg. No. 8050-31-5) when used as an inert ingredient (surfactant) on growing crops and raw agricultural commodities pre- and post-harvest. Croda Inc. submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting establishment of an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of resin acids, esters with glycerol when used in accordance with the terms of the exemption.

## Effects PRIA read

- Tolerance Exemption for Surfactant Use: benefit, medium. Effective June 18, 2026, EPA exempts residues of resin acids, esters with glycerol (CAS No. 8050-31-5) from the requirement of a tolerance when used as an inert surfactant on growing crops and raw agricultural commodities pre- and post-harvest. EPA says no numerical residue limit or analytical enfo…
- 50% Cap Enforced in Registrations: mixed, medium. EPA will not register any pesticide formulation for food use that exceeds 50% resin acids, esters with glycerol in the finished pesticide formulation. The 50% maximum concentration will be enforced through the pesticide registration process, so manufacturers must keep this ingredient at or below 50…
- EPA Finds No Safety Concern: benefit, low. EPA concluded there is a reasonable certainty that no harm will result to the general population, including infants and children, from aggregate exposure to residues of resin acids, esters with glycerol when used as allowed by this rule. You can expect EPA determined available toxicity data show lo…
