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.
Read MoreOverall, this project clearly demonstrates benefits to diversity in IWM tactics studied, and the ability to eliminate herbicide application for three years although it may require significant compromises to the desired rotation. 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.
Read MoreThe broad phenotypic variation captured by the NAM population provided valuable novel genetic variations for the Canadian spring wheat breeding program. The high-quality haplotype map generated from this project could allow breeders to accurately impute genotypes with a low-resolution genotyping platform in their breeding program. Novel genetic variations for disease and agronomic traits identified by the NAM analysis provide new targets and breeder-friendly markers for wheat improvement. These established NAM genomic resources may also serve as a cost-efficient platform for Canadian wheat breeding programs to identify genetic markers of their targeted traits, as only phenotyping is required.
Read MoreHerbicide resistant weeds continue to increase in incidence and frequency, limiting weed management options available to producers. New management strategies are needed for producers to continue to successfully manage their weeds. Harvest weed seed control (HWSC) is a paradigm of weed control that focuses on managing weeds that are being spread by the combine harvester. These weeds retain their seeds until crop harvest, produce weeds at a height where they can be collected, and are successfully taken into the combine. One method of harvest weed seed control that may have a fit in western Canada are the physical impact mills.
Read MoreThe number of unique herbicide-resistant weed/site of action combinations continues to increase in Western Canada and around the world. The lack of new herbicides with a unique mechanism of action is leading to the development of alternative cultural and mechanical weed control practices.
