An opinion piece argues that Mexico's decree banning GM corn imports is not supported by production data, with domestic yields around four tons per hectare. It says the government's goal of cutting GM corn imports by 50% by 2024 is unrealistic without GM varieties, glyphosate and farm support.
The author questions whether the country can raise output through agroecology.
If Mexico cannot replace imported corn with domestic production, it will still need large imports, which limits how much the GM corn ban reduces US export demand.
After 439 past neutral policy events, Corn moved a median +0.1% over 5 sessions (51% higher; middle half -1.3% to +1.2%), and +1.1% over 20.
