The Challenge
The last Alberta general weed survey was conducted in 2010.
The Project
Update the abundance, distribution and changes of weed species in major annual crops across Alberta. Herbicide-resistant weeds will also be surveyed to asses their populations and strategies moving forward.
The Results
142 weed species were identified in 1232 fields of wheat, barley, durum, oat, canola, lentil or pea crops surveyed in Alberta. The most abundant weeds of the province were found to be chickweed, wild buckeat, lamb;s-quarters and volunteer canola. Weed ranking differed by crop and region. Most weed species have not decreased in frequency over time. 59% of surveyed fields showed herbicide resistant weeds, with Group 1 resistant wild oats being the most common.
Grower Benefits
By identifying shifts in weed species and herbicide resistant biotypes, growers can develop ecologically and economically sustainable strategies in weed management.
