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 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.
Webinar hosted by WeedSmart western extension agronomist, Peter Newman.
Wednesday 30th of March
9:30am AWST / 12:30pm AEDT
