Pre-emergent herbicides in stubble

The latest research by Dr Yaseen Khalil from AHRI has compared the effect of rainfall on leaching of Sakura (pyroxasulfone), Arcade/Countdown (prosulfocarb) and trifluralin applied to wheat stubble. Take a listen to find out what the results were from Dr Khalil himself!

Wild radish resistant to Atrazine, very sensitive to Bromoxynil

Some new research by AHRI PhD student, Huan Lu, has shed some light on Atrazine resistant wild radish and the results have some very practical applications for growers and agronomists. The most common target site mutation that causes Atrazine resistance in wild radish is the 264 mutation, the same mutation that gave us TT Canola. They have very high resistance to Atrazine and as it turns out they are super-sensitive to Bromoxynil, requiring only about a third of the Brom rate that it takes to kill susceptible wild radish. Wild radish with the 264 mutation is also resistant to metribuzin….

AHRI celebrates 20 years this coming Sunday

AHRI was a GRDC initiative which started back in 1998 under the guidance and direction of Professor Stephen Powles. This coming Sunday the AHRI Team will be hosting a dinner with AHRI stakeholders to celebrate AHRI’s 20-year milestone. Many significant discoveries and practice changes have come about through AHRI being in existence. AHRI Centre Manager Lisa Mayer provides an overview of some of the significant achievements AHRI has had over the last 20 years and also delves into the future direction the research group is heading in.

Research highlights in weed science for 2018

It’s been a big year for AHRI. Former AHRI Director, Stephen Powles retired from the position earlier in the year, with Professor Hugh Beckie from Canada taking on the role. We also saw the opening of the GRDC-funded Agronomy Laboratory at the University of Western Australia. Research is at the core of what we do though and we didn’t do that in halves this year either! Not only did AHRI produce significant papers, but other weed science groups nationally also made important discoveries. In this podcast, AHRI Director Hugh Beckie gives an overview of the year that was and provides…

Swathing and desiccation as a tool to control ryegrass seed-set

Today on AHRI Snapshots, we’re speaking with Development Officer Glen Riethmuller, from the Department of Primary Industries and Regional Development Western Australia, about spray swathing and desiccating canola for ryegrass seed set control. Take a listen

What’s the relationship between crop competition and harvest weed seed control?

In this edition of AHRI Snapshots, we’re speaking with Director of Weed Research at the Plant Breeding Institute, University of Sydney, Michael Walsh about a recent research paper on crop competition and its influence on harvest weed seed control on ryegrass. We know crop competition is great at suppressing weeds, but what we have learned from this research is that crop competition makes other weed control techniques, such as harvest weed seed control work better. Take a listen to learn more!
