I've read the same thing. It is Roundup, and it's not just wheat, they spray it on oats too. It kills the crop, and any weeds. Then the combines can harvest the wheat faster because the totally dead plants cuts better, and there are less instances of the combine binding up, which causes them to shut it down to clean out the stuff that didn't cut. They also don't allow the GMO seeds which has taken over much of our crops. However, I am encouraged by some new generations taking the family farms to organic. That's encouraging.
