Herbicide resistance

Patent Granted One of the most prevalent type of GM crops have a "Roundup Ready", or glyphosate-resistant trait.[32] Tobacco plants have been engineered to be resistant to the herbicide bromoxynil.[24] Crops have been commercialized that are resistant to the herbicide glufosinate, as well.[81] As weeds have grown resistant to glyphosate and other herbicides used in concert with resistant GM crops, companies are developing crops engineered to become resistant to multiple herbicides to allow farmers to use a mixed group of two, three, or four different chemicals.
