The Challenge
Recent 2014-2017 estimates suggest that 59% of fields in the Canadian prairies are infested with at least one herbicide-resistant weed biotype, and that herbicide resistance costs prairie farmers an estimated $530 million annually in reduced crop yield, quality, and increased cost of weed control1.

The Project
Develop the Prairie Weed Monitoring Network (PWMN) and implement a comprehensive weed biovigilance strategy for the prairie region of Canada, including weed monitoring, risk assessment, and forecasting.
The Results
This section will be updated upon completion of the project.
Grower Benefits
This coordinated suite of objectives will provide farmers with information required to manage weeds effectively, anticipate new weed threats to farming systems, and mitigate selection pressure for herbicide resistant weeds.
