Phenol; Revoking Exemption From the Requirement of a Pesticide Tolerance
EPA proposes to revoke the tolerance exemption for phenol as an inert ingredient in pesticide formulations, requiring removal from products and label changes.
Aforeworn detected this change in the Pesticide & Pest-Control Applicators space on July 6, 2026 and published this briefing so affected operators are forewarned rather than caught off guard. It is rated High urgency. Pesticide formulators, structural pest-control firms, lawn/ornamental applicators, agricultural applicators, fumigation companies should confirm how it applies to their specific situation before acting. There is a time constraint attached: By effective date of final rule (typically 30-60 days after publication in Federal Register).. Acting after that point can mean penalties, a lapsed licence, or lost eligibility — exactly the kind of surprise Aforeworn exists to prevent. Aforeworn monitors Pesticide & Pest-Control Applicators continuously and turns every detected change into a plain-English briefing like this one, so you always know first. Forewarned is forearmed.
