Herbicide resistant weeds are no longer a novelty, they’re the norm

By
Hugh Beckie, a research scientist with Agriculture and Agri-Food Canada, said it’s a challenge to get farmers to implement herbicide-resistance best management practices (BMP) because growers are diverse, and one size doesn’t fit all. But Beckie has found that growers who use BMPs tend to have less herbicide resistance. So, in the spirit of David

advises AAFC’s Hugh Beckie

By
Tank mixing two herbicides with different modes of action targeting the same weed is a good way to delay the development of herbicide-resistent weeds, a study by weed scientists at the University of Illinois and United States Department of Agriculture concludes. “We don’t say that mixing is the end-all solution,” study co-author Pat Tranel of
