This research was conducted in an incubator in Saskatoon, SK, in 2021. The stimulants of interest were pyroligneous acid, also known as wood vinegar or smoke water, as well as potassium nitrate, a form of nitrogen fertilizer. Potassium nitrate was chosen due to widespread use of nitrogen fertilizers and familiarity for farmers since equipment and knowledge is already present. Smoke water was chosen due to previous research and that wild oat may be sensitive to smoke due to fires frequenting the prairie and forest before widespread agricultural adoption.

Lower responsiveness from twining weeds like wild buckwheat and cleavers illustrate a gap in our current IWM strategies based on the growth morphology of these weeds. In addition there is a need to understand the lack of impact of perennials and silaging on specific weed species and their weed seedbank densities.
Read MoreThe study objective was to survey glyphosate-resistant and dicamba-resistant kochia within Manitoba in 2018, Saskatchewan in 2019, and Alberta in 2021. Kochia seed was collected at approximately 300 sites in each province. Samples were threshed and seeded in the greenhouse then sprayed with labeled doses of glyphosate or dicamba then evaluated after 3 or 4 weeks, respectively.
