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.

Hoe, hoe, hoe and away weeds go!

Mon, 18 May 2020

How many hours did you spend out in the paddock with a chipping hoe when you were a kid? Do you still carry one in every ute? Chances are you know how effective they are; but wouldn’t mind if you never had to use one again! Australia has an unfortunate habit of claiming world-firsts in new species for the herbicide resistance lists. Fortunately, we have also been leaders in the development of new tools to help combat the problem. Enter: the revolutionary new chipping hoe! The latest of these developments is the world’s first site-specific mechanical weeder.

Publications Interactions between crop sequences, weed populations and herbicide use in Western Australian broadacre farms: findings of a six-year survey

Wed, 13 May 2020

Six years of survey data taken from 184 paddocks spanning 14 million ha of land used for crop and pasture production in south-west western Australia were used to assess weed populations, herbicide resistance, integrated weed management (IWM) actions and herbicide use patterns in a dryland agricultural system. Key findings were that weed density within crops was low, with 72% of cropping paddocks containing fewer than 10 grass weeds/m2 at anthesis.
