Negative Cross-Resistance Helps Scientists Outmaneuver Herbicide-Resistant Weeds

Thursday, September 13, 2012 - 18:00 in Earth & Climate

Kochia, a weed that is rapidly becoming more abundant across southern Canadian prairies and the Great Plains of the United States, can reduce crop yields by up to 60 percent. Fighting this weed has become difficult because more than 90 percent of kochia populations are now resistant to acetolactate synthase (ALS)-inhibiting herbicides. The phenomenon of negative cross-resistance, however, may offer another path to defeating the spread of this weed.
