Evolution of Herbicide Resistance Across Western Canada
The article traces herbicide resistance from the late 1980s in southwestern Saskatchewan and southern Alberta with Group 2 resistance to chlorsulfuron and Glean, spreading via chemical fallow with Sweep. It notes early weed resistance in Manitoba, the rise of Group 1 and Group 2 products through the 1990s, and the shift to glyphosate tolerant crops in the 2000s, plus future multi mode of action strategies.
