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.
Reversing trifluralin resistance
Mon, 7 Sep 2020
They said it couldn’t be done – climbing Everest, flying to the moon and even deep-frying Mars bars. We were also told that we couldn’t reverse herbicide resistance. In the majority of cases, the experts are right – herbicide resistance is permanent, and we thought that was the case for all resistant weeds. Until now…
Loss of trifluralin metabolic resistance in Lolium rigidum plants exposed to prosulfocarb recurrent selection
Tue, 11 Aug 2020
This study provides evidence that trait(s) enabling efficient trifluralin metabolism in L. rigidum are purged from the population under prosulfocarb recurrent selection.
It is speculated that survival to prosulfocarb via a lack of metabolic herbicide activation, and survival to trifluralin conferred by enhanced herbicide metabolism, are mutually exclusive.
