Glyphosateresistant kochia survey

November 13, 2015

KEY PRACTICE: Taking action to manage glyphosateresistant kochia before it is visible in the field is critical to success. Use a rotation of broadleaf control products with good activity on kochia.

PROJECT TITLE, LEAD RESEARCHER: “Glyphosate-resistant kochia (Kochia scoparia L. Schrad.) in Saskatchewan and Manitoba,” 2013-14, Hugh Beckie, Agriculture and Agri-Food Canada (AAFC)


As the most-widely used herbicide in Western Canada and around the world, glyphosate popularity has led to global selection for glyphosate-resistant (GR) weeds. Kochia was the first GR weed in Western Canada, confirmed present in southern Alberta in 2011. The efficacy of herbicides is much stronger on weeds when they are small, and taking measures against GR kochia before it is visible in the field is critical to successful management.

Hugh Beckie, who accurately predicted that kochia was becoming glyphosate resistant, continues to study options for its control. Building on kochia surveys conducted in Alberta in 2011 and 2012, 615 sites across southern Manitoba and southern and central Saskatchewan were surveyed in the fall of 2013.
