I pulled quite a bit of this from a small 5' x 100' bed that wasn't properly 
mulched.  I can't imagine a conventional farmer with several hundred acres 
dealing with pigweed as it becomes a superweed.
Suspected glyphosate-resistant pigweed on upswing

The Hefty brothers ( Ag PHD at RFD TV) were saying recently that the problem 
is made worse when weeds that are slightly resistant to a glysophate recieve 
a light dose a few may excape. What results is a selection process that you 
dont intend when you use less than the max reccomended. More and more I hear 
them talking tank mixes on RR and LL crops.
