Background

Canada is home to the third-largest number of unique herbicide-resistant (HR) weeds. The cost to manage HR weeds annually is estimated to be $528 million annually. HR weeds can be difficult to manage and can result in increase crop yield losses. Management of HR weeds requires cooperation among researchers, specialists, agricultural industry, agronomists, and growers. This study is a continuation of previous rounds of prairie HR weeds surveys (2014-2017), the goal is to complete a 4th round of prairie HR weeds surveys , develop prairie wide maps of HR weed biotypes, and implement a coordinated strategy for surveillance of HR weeds in the Canadian prairies.

Objectives

  1. Develop prairie-wide maps of herbicide-resistant weed biotypes using the data from past herbicide-resistant weed surveys
  2. Conduct a comprehensive survey herbicide-resistant weeds in 400 fields in Saskatchewan in 2019/2020
  3. Offer diagnostic testing for suspected cases of novel herbicide-resistant weeds in western Canada

Key Takeaways

  • Conducted a 4th round of prairie herbicide resistant weed surveys.
  • Developed maps for the each province in western Canada showing the herbicide resistant weed biotypes found.
