Mexican President Andrés Manuel López Obrador issued a decree in 2021 to eliminate genetically modified (GM) corn in Mexico by 2024 and ban the use of glyphosate herbicide by 2024, affecting both imported and exported corn. The decree has been modified and issued in February 2023, maintaining the ban on GM corn for human consumption and glyphosate use while removing the deadline for animal feed and industrial use. The decree has sparked discussions with the U.S. regarding its compliance with the USMCA, and the American Seed Trade Association expresses concerns about the potential impact on innovation and the U.S. economy. In Mexico, the decree affects the corn seed trade, with producers seeking more robust hybrids rather than GM technology. The decree also aims to protect native corn species and has been in effect since 2021 due to a ongoing lawsuit.
