What is AHRI?
Welcome to The Australian Herbicide Resistance Initiative (AHRI) homepage! Before you dig into all our publications and podcasts, you might be wondering who we are and what we do. AHRI was a GRDC initiative which launched in 1998 under the guidance of Professor Stephen Powles. In 2018, we celebrated 20 years of GRDC funding, operating as a research group out of the University of Western Australia. You can get a great overview of what we’re all about by watching the video on the right. You can also learn more in this Outlooks on Pest Management article here.
LiDAR to detect and map tall weeds at harvest
Tue, 2 Nov 2021
AHRI researcher, Dr Mike Ashworth, has spent years driving around the WA wheatbelt, spotting tall weeds sticking out of the top of wheat crops, wondering if there was a way to detect and map these weeds. He set out to develop just such a tool with help of other AHRI researchers, led by Nooshin Shahbazi, in collaboration with Stealth Technologies. The team used LiDAR (Light Detection and Ranging) and found they could detect and map up to 97% of weeds that were sticking out of the top of a wheat crop. Not a bad effort for a first-up attempt!
Mechanical scarification technique breaks seed coat-mediated dormancy in wild oat (Avena fatua)
Tue, 16 Nov 2021
Wild oat is a herbicide resistance-prone global weed species that causes significant economic losses in dryland and horticultural agriculture. As a result, there has been a significant research effort in controlling this species.
