New research provides insights into annual ryegrass control options for Canola farmers

Annual ryegrass is a major weed of crops across southern Australia and has evolved resistance to many of the herbicides making management in canola challenging.

New research by Dr. Christopher Preston from the University of Adelaide has examined the efficacy of different herbicide strategies in TruFlex/Clearfield canola compared to TruFlex, Clearfield, Clearfield/TT and TT to determine the best management practices for annual ryegrass control.

Presented at the GRDC Perth updates in February 2021, the research and field trials found:

  • Stacked tolerance in canola offers multiple options and timing to control annual ryegrass.
  • Good early weed control is essential to reducing weed numbers in crop.
  • Resistance to the imidazolinone herbicides is present in most annual ryegrass populations making strategies reliant on these herbicides ineffective.
