Resistance Among Certain Common Herbicides
January 28, 2011| |
Dr. Paul Baumann, a Texas AgriLife Extension Service state weed specialist, recommended that farmers need to go back to some of the old chemistry or use new products with different sites of action other than the product in question – glyphosate. "Glyphosate is a highly effective herbicide that controls a large number of weeds and can be used safely in crops that have glyphosate-resistant genes," Baumann said. It has been well documented though that the continued use of glyphosate and some other factors have resulted to the evolution of glyphosate resistant weeds.
The development of herbicide resistance in plants was likened and discussed to be similar with the development of humans to prescription drugs. In plants, state weed specialist said that "the key to all of this is the development of new chemistries that have different sites of action or simply the use of other products that have a different site of activity in the plant."
