Glyphosate is the most commonly used herbicide in the world and an integral part of the global agricultural system, due dominantly to the widespread adoption of genetically modified glyphosate resistant crops. In its traditional use as a broad spectrum herbicide, it is either sprayed before planting crops to clear a field, or as a maintenance tool after planting if applied to glyphosate-resistant crops. These uses, however, differ from the practice of crop desiccation, which aims to increase the rate at which a plant loses moisture to change the timing of a harvest. The concern with this kind of use, which would occur 7 to 10 days before harvest, is that it would leave increased amounts of glyphosate residue on final product because its application is closer to harvest time.
