US EPA Withdraws Interim Registration Review Decision for Glyphosate
Effective September 23, 2022, the United States Environmental Protection Agency (US EPA) announced its withdrawal of the interim registration review decision for the herbicide glyphosate. This update allows products containing glyphosate to remain on the market as well as continued use according to the product labels and application instructions.1 The US EPA is currently conducting a registration review of glyphosate, which is required every 15 years, and expects to complete the review by 2026.
Glyphosate is used to target broadleaf weeds and has been widely used with genetically modified glyphosate-resistant crops such as soybean and cotton. Glyphosate has become increasingly controversial, with mixed reports regarding possible health effects and human exposure concerns.
CIL offers stable isotope-labeled and native standards of glyphosate and its metabolite AMPA, as well as the alternative use herbicides glufosinate and dicamba.
