[AT] Round-Up resistant weeds

[charliehill]

I first started hearing of glyphosate resistant weeds probably 8 or 10 years 
ago in continuing ed classes for my private pesticide license.  The 
instructors said it was starting to show up in certain weeds and that it was 
just a matter of time before it became a big problem.  I guess the time has 
about come.
