Controlling seeds post-harvest

Can pulverizing weed seeds after harvest control weeds in Western Canada?

By
As buzz builds about Australia’s Harrington Seed Destructor, researchers are looking at whether pulverizing seeds after harvest will work on the Prairies. But preliminary research shows post-harvest seed control is unlikely to work for all of Western Canada’s weeds. Breanne Tidemann presented new research at the Herbicide Resistance Summit in Saskatoon this March. Tidemann, who is […] Read more

Managing Group-2 resistant weeds in pulse crops across Western Canada

Cleavers, mustard, kochia and sow thistle are among the weeds getting harder 
to control, but there are methods, starting with good agronomy

By
Group 2 resistance is something that is really a big problem across Western Canada,” says Dr. Chris Willenborg, a researcher at the University of Saskatchewan’s plant sciences department. Willenborg has worked on several research projects that inform weed resistance in pulses. The bad news is that resistance is spreading. And the more farmers rely solely […] Read more
