A dessicant is generally not used in temperate climes for harvesting grain. The fact that Lithuania's climate is so soggy that farmers kill the crops with pesticides to induce the seeds to dry, has little relevance to Saskatchewan or the Dakotas or Kansas, where the ripening grain coincides with the hottest and driest period of summer.

If Canadian food has significant glyphosate in it, this should caution us that glyphosate is not biodegrading as rapidly as previously thought. Most glyphosate goes on before fields are tilled, to kill weeds. Normally a glyphosate-resistant crop such as hybrid corn is then planted and further cultivated mechanically to keep surviving weeds down. Wheat and rye crops are typically rotated after the corn crop, and those often are further rotated with lentils or dry beans.

What should be concerning about these findings, is that glyphosate or its metabolites may not rotting nearly as fast as stated on their EPA labeling. A metabolite residue that's showing up months after application, and makes it into the human diet, should prompt further review.

Of course, another factor to be considered is that the dosages humans are getting, may not be dietary.

Glyphosate is commonly used on ornamental flower-gardens and lawns for weed control. It is usually sprayed, creating an aerosol fog. Frequently it is used far in excess of label directions, as amateur gardeners find that at the EPA-permitted dosages, their lawns and flower beds just don't quite look beautiful enough.

The manufacturers and distributors of glyphosate and all other pesticides are obligated by law to put down on the label what EPA authorized. But if consumers are going to overuse these products, the manufacturers are not required to step in and limit sales. Since most humans live in cities where lawns are commonplace, inhaled glyphosate may be a bigger medical problem than we initially guess.

We lived in a rural area in Brazoria co. TX and they often resorted to spraying weed killer rather than mowing the roadsides. Spray went everywhere.

I might have added those roads ran next to rice paddies. Most if not all was sold to Iraq I guess because when the fighting began they switched to, my wife thinks rapeseed I thought some fodder for cattle, but now??? Maybe solar energy farms.

Glyphosate kills the grass, so it's not what is being sprayed on the lawns. Glyphosate is used along edges and fences. It's perfectly safe as long as used properly. Don't spray it on your shoes.

TDoug; It's perfectly safe is something I've heard before. In the case of the widespread use in farmlands the damage to the air, water and soil is extreme. There are graphs showing the most concentrated areas, the mid-west is one of the areas.
