Peter, the article you posted:
http://westernfarmpress.com/news/newest-herbicide-resistance-technology-unveiled-0809/
was about how the chemical/biotech industry continually has new 
solutions (e.g.  Glytol Liberty Link technology from Bayer CropScience)
in the pipeline to address emerging new herbicde resistance problems 
such as the Palmer amaranth pigweed glyphosate resistance problem 
in certain areas of the deep South.

Your original point was: "imagine new types of weeds coming about that 
are much more resistant to herbicides due to unexpected crossing of 
herbicide resistant varieties of canola" implying that grave new superweed
problems could develope that the chemical/biotech industry 
failed to anticipate and could seriously jeopardize crop  
yields and the economic health of farmers on a landscape scale. 

My point is the chemical/biotech industry is not that naive and
doesn't make mistakes of that magnitude hence we are not 
seeing farmers or their trade associations rising up in rebellion 
against the GM technologies offered by Monsanto, Syngenta, 
Bayer, etc.
