A growing resistance problem in Canada
The rising tide of weed resistance—especially the surge of kochia in the west—is wreaking havoc for Canadian farmers. It eats away at profits, makes fields ugly, steals time and patience (and sanity).
According to a recent Weed Resistance Study conducted by Real Agristudies, farmers expressed a high degree of concern about the impact of weed resistance, and largely agree that ‘the industry needs to do a better job of helping them manage weed resistance’. There is also high hope that new technologies will save the day.
Kochia resistance continues to evolve.
Kochia is easily becoming one of the most troublesome weeds because the herbicide options to control it are decreasing. Since 1980, kochia has evolved significantly
—and today 45% of the kochia populations are resistant to multiple groups of 2-, 4-, 9-, and 14-herbicides.
