It's a plant killer, you're not going to spray it on crops, you spray it on plants you don't want to grow around your crops.

It's actually sprayed on food before harvesting. It's called crop desiccation.

Hrmm, never heard of that. It goes the complete opposite way of the Roundup Ready crops.

Well, that technique won't work on Roundup Ready crops. But it's used on things like wheat that are supposed to be dried out when harvested.

Desiccation is done to increase yield. Stressed / dying plants produce more seed.

Seems like you could spray it on Roundup Ready plants, since the point of Roundup Ready plants is to not die from being sprayed with Roundup.

With corn and cereal, you actually want to weaken or kill the plants some days before you harvest, so they start to dry, especially if the weather has been wet. You get a drier harvest with less chance of spoilage in storage.
