A friend has 2000 acres or so of non GMO soybeans near Bryan.  He is a really good farmer but his Marestail control got out of hand this year.  It wouldn't matter if it was non GMO or not, I've seen worse in RR beans.  Marestail is that big of a problem.

We were at his place in late June and we talked over Marestail control.  Mine is in hand at this moment but could break out again at any moment.  I have Giant ragweed and common ragweed doing the same thing here.

Out of control.
