I eat ORGANIC grains to avoid exposure to glyphosate, even as a pre-harvest dessicant. If you think you are glutton sensitive, speak to your MD about trying organic & see if your digestion improves in the absence of GLYPHOSATE (the active ingredient in the widespread herbicide Roundup).

Why glyphosate is used before harvest:
Crop Desiccation:
The primary use is to dry down the crop, allowing for a faster and more uniform harvest.
Weed Control:
It kills weeds that grow late in the season, which can hinder harvest by damaging equipment, increasing moisture content, and contaminating the harvested grain.
Harvest Efficiency:
By ensuring the crop and surrounding weeds are dry, glyphosate application can make the threshing process easier and more efficient.
When and how it’s applied:
Timing:
Glyphosate is applied when the crop is fully mature and the grain’s development is complete.
Crop Conditions:
It’s often used in years with wet conditions that prevent the crop from drying naturally.
Harvest Restrictions:
Glyphosate products have specific harvest intervals (harvest waiting periods) that must be followed to ensure the residue levels in the grain are well below established safety limits.
Key considerations:
Crop Maturity: To avoid residue issues, the crop must be mature enough before application, with the least mature seeds below a certain moisture threshold, typically 30%.
Regulatory Compliance: Proper application timing and adherence to label guidelines are crucial for meeting Maximum Residue Limits (MRLs) and accessing export markets.
Not for Seed Crops: Pre-harvest application of glyphosate is not recommended for seed crops.
