The U.S. Environmental Protection Agency (EPA) has extended its Emerging Viral Pathogen (EVP) Guidance for Antimicrobial Pesticides (Guidance) in response to the mpox virus (formerly monkeypox), which had been considered to be a rare disease caused by infection with the mpox virus. EPA developed its Guidance in 2016 to address emerging pathogens. Under this Guidance, EPA provides pesticide registrants with a voluntary “two-stage process to enable use of certain EPA-registered disinfectant...

The U.S. Environmental Protection Agency’s (EPA) deadline for Spanish language bilingual labeling compliance reporting under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) (as amended by the Pesticide Registration Improvement Act of 2022 (PRIA 5)) via MyPeST is July 31, 2026. This reporting deadline is limited to restricted use pesticides (RUP) and agricultural products (non-RUPs) in Acute Toxicity Category I. EPA’s MyPeST platform is a web-based system designed to replace...
The U.S. Environmental Protection Agency’s (EPA) Office of Pesticide Programs (OPP) has provided new resources to assist users with their MyPeST applications. EPA’s MyPeST platform is a web-based system designed to replace the Pesticide Submission Portal, offering registrants a transparent dashboard for tracking application statuses and managing bilingual pesticide labeling compliance. The MyPeST User Guide (Version 3.0.1, dated July 8, 2026) is available now. EPA states that the User Guide...

The Surprising Science Shift That Changed His Career — A Conversation with Richard J. Fehir, Ph.D.
For more than a decade, litigation over glyphosate-based herbicides has sat at the intersection of federal pesticide regulation, state tort law, scientific risk assessment, and broader debates over the role of juries in evaluating product safety. The Supreme Court's June 25, 2026, decision in Monsanto Company v. Durnell (Durnell) represents the Court's most significant interpretation of the Federal Insecticide, Fungicide, and Rodenticide Act's (FIFRA) preemption provision since Bates v. Dow...

The U.S. Supreme Court issued one of the most significant pesticide law decisions in years on June 25, 2026, holding in Monsanto Co. v. Durnell that the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) expressly preempts state-law failure-to-warn claims that would require pesticide labels to include warnings beyond those required by the U.S. Environmental Protection Agency (EPA). The Court's 7-2 decision is expected to have far-reaching implications for pesticide manufacturers,...
In a significant move toward modernizing chemical safety assessments, on June 2, 2026, the U.S. Environmental Protection Agency (EPA) announced two major actions aimed at replacing traditional, animal-based testing with advanced scientific alternatives, typically known as New Approach Methods (NAM), for chemical assessments under the Toxic Substances Control Act (TSCA) and Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). EPA is also introducing a streamlined process for researchers,...
