[AT] Round-Up resistant weeds

[Al Jones]

Palmer amaranth aka pigweed is the bad one around here.  In the early days 
of Roundup Ready, a whiff of Roundup would devastate a pigweed that was 7' 
tall--they were VERY sensitive to it.  I think some of the problem with the 
technology is it has been over used and even abused--it's not a silver 
bullet.
