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
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
Practical ways to fight herbicide resistance
Do you have herbicide resistant weeds growing in your field?
Brian Wintonyk wants farmers to be able to identify herbicide resistant weeds in their fields and know what to do about them. Wintonyk, western crops agronomist with Dow AgroSciences Canada Inc., was on the agenda at the third annual Grain Expo, a crop production conference held in Regina in conjunction with Agribition in November. He […] Read more
Farming was the right choice
After 40 years of farming, Blair Rempel knows he made the right choice when he chose to come back to the farm
Blair Rempel has been farming for almost 40 years. The Nipawin area producer and seed grower earned his diploma in agriculture at the University of Saskatchewan, in 1976. He considered other careers but always came back to agriculture. “The things I found attractive was a certain degree of independence and the satisfaction of building your […] Read more
Diversify rotations to slow resistance
Diversify canola-wheat rotations to save profit margins and slow weed resistance, before it’s too late
Scientists warn that a serious threat to sustainable crop production in Canada continues to grow. Surveys indicate the number of western Canadian fields containing Group 1 and Group 2 herbicide-resistant weeds has jumped dramatically. In addition, glyphosate-resistant kochia continues to spread rapidly in the west, while glyphosate-resistant giant ragweed, Canada fleabane and common ragweed carry […] Read more
