Presented by Hugh Beckie, Weed Scientist, Agriculture and Agri-Food Canada and Adjunct Professor, Department of Agricultural, Food and Nutritional Science at the University of Alberta
Since the initial discovery of herbicide-resistant (HR) weeds in the late 1980s in Western Canada, the majority of annual cropland across the prairies is now affected by HR weeds – most notably wild oat, green foxtail, kochia, and cleavers.
Beckie will discuss the results of the 2014-15 Saskatchewan weed resistance survey and the 2016 Manitoba survey (Alberta was surveyed in 2017 but results pending), as well as 2012-2016 test results of samples submitted by producers or industry.
Additionally, the results of Saskatchewan and Manitoba producer management questionnaires regarding adoption of weed resistance management practices and cost of resistance will be highlighted, in the context of recommended best management practices.
