There is roundup-ready Cotton, Soybeans, Corn and Canola, that I am aware of. My family grows Roundup-ready cotton. The other 2 are used for animal feed; in no case is any farmer going to be spraying it when it is fruiting, because once the weeds have got to that point you've already lost all the benefit of it being 'roundup ready' - where the purpose is for weeds to be killed so they don't take the moisture which is now conserved for the crop.

There are no roundup-ready vegetables that I am aware of, or fruits.
