In reply to flatlandrich:
> Why would farmers spray Glyphosate on a growing crop they were planning on harvesting?
It's already on the seeds and it's taken up by the plant, and there are other herbicides that are sprayed which kill the weeds, but not the wheat.
If you buy any cereal product that is not organic, it will have glyphosate and others in it. Pasta, bread, breakfast cereal... anything with wheat, oats, maize or barley in it.
