Mexico Enacts Ban on 35 Pesticide Molecules

The decree marks phase one of a national plan that schedules additional prohibitions in 2026 and 2027.

Overview

  • The Diario Oficial published the decree on September 4, making it effective today; regulators ordered cancellation of registrations within 10 days and disposal of existing stocks within six months, with imports limited to research or analytical use.
  • The prohibition covers the importation, production, commercialization, use and final disposition of 35 active ingredients across the country.
  • Officials cited health and environmental risks and pointed to international alignment, highlighting aldicarb, carbofuran, endosulfan and DDT among the banned substances.
  • The measure is coordinated by Agriculture, Health/COFEPRIS, Environment and Economy, and reflects commitments under the Basel, Rotterdam and Stockholm conventions.
  • Advocacy groups such as RAPAM criticized the scope as insufficient, noting about 200 hazardous ingredients remain authorized and that widely used products like chlorpyrifos‑ethyl, glyphosate, fipronil, neonicotinoids and paraquat were excluded.
