- Increased adoption of crops with stacked traits conferring glyphosate and dicamba resistance, and recent confirmation of kochia [Bassia scoparia (L.) A.J. Scott] biotypes resistant to these herbicides in Alberta and Saskatchewan, warrant surveillance of herbicide-resistant kochia in Manitoba. A randomized–stratified survey of 315 sites in Manitoba was conducted in the fall of 2018. Overall, 58% of the kochia populations tested were glyphosate-resistant, while 1% were dicamba-resistant. This survey documents rapid increase in glyphosate-resistant kochia over a five-year time frame, and also confirms the first cases of kochia in Manitoba with dicamba resistance alone and in combination with glyphosate resistance.

- La culture de variétés cumulant la résistance au glyphosate et au dicamba ainsi que la confirmation récente de biotypes de kochie [Bassia scoparia (L.) A.J. Scott] résistants à ces herbicides, en Alberta et en Saskatchewan, justifient qu’on vérifie s’il n’y a pas de kochie résistante à ces herbicides au Manitoba. À l’automne 2018, les auteurs ont effectué une étude stratifiée aléatoire à 315 endroits de la province. Globalement, 58 % des peuplements de kochie testés résistaient au glyphosate, contre 1 % au dicamba. Cette enquête montre que la kochie résistante au glyphosate a vu sa population augmenter rapidement en cinq ans. Elle confirme de surcroît l’existence des premiers spécimens de kochie résistants au dicamba et aux deux herbicides, au Manitoba.
