Glyphosate-resistant (GR) canola is a widely grown crop across western Canada and has quickly become a prolific volunteer weed. Glyphosate-resistant soybean is rapidly gaining acreage in western Canada. Thus, there is a need to evaluate herbicide options to manage volunteer GR canola in GR soybean crops. The present experiment was conducted to evaluate the efficacy of various PRE- and POST- emergence herbicides applied sequentially to volunteer GR canola, and to evaluate soybean injury caused by these herbicides. Trials were conducted across Saskatchewan and Manitoba in 2014 and 2015. All treatments provided a range of suppression (>70%) to control (>80%) of volunteer canola. All treatments with the exception of the glyphosate treated control reduced aboveground canola biomass by 96% (on average). As well, canola seed contamination was reduced from 36% to less than 5% when a PRE and POST herbicide were both used. Moreover, all combinations of herbicides used had excellent crop safety (<10%). All Pre and Post herbicide combinations provided better control of volunteer canola compared to the glyphosate only control, but tribenuron fb bentazon and tribenuron fb imazamox+bentazon provided solutions that were low cost, currently available (registered in western Canada) and had the potential to minimize development of herbicide resistance in other weeds.
