First case of glyphosate & paraquat resistant annual ryegrass found in WA crop field

AHRI Snapshots

For the first time in Western Australia, annual ryegrass from a cropped paddock was found to be resistant to glyphosate and paraquat (among other modes of action).

AHRI Senior Research Fellow Dr Roberto Busi joins us on the podcast today to give an overview of this finding as a pre-cursor to an upcoming WeedSmart webinar.
In this webinar, he will present the preliminary results he obtained in recent glasshouse trials, which aimed to characterise the resistance.

Farmanco Agronomist Consultant Brent Pritchard will provide some context on how this resistance evolved in the field.

Roberto will conduct two field trials in 2022. He will explain what treatments he’s planning to test, and attendees will have the opportunity to provide feedback on those treatment options.
