The canola crop across Western Canada can be summed up in one word: variable. Ranging from full flower to swathed, the bulk of the crop is creeping through maturity after several weeks of cool summer temperatures. As a late summer push of warm weather descends, farmers need to be vigilant in protecting the turning crop from creepy crawly yield suckers such as lygus bug.
In this Canola School video, Clint Jurke, agronomy specialist for Saskatchewan with the Canola Council of Canada, discusses the threat of cabbage seedpod weevil (which has passed for most of the canola crop now) and lygus bugs. Lygus do the bulk of their damage during the pod phase; as few as 15 per sweep at podding could mean it’s time for control. In this video, Jurke shows us how to sweep and what to consider when determining a workable economic threshold for your farm. The Canola Council of Canada has a handy table to help. View that here.
