GRDC Crop Updates Perth 2021
Find out more here!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.

Fencelines, roadsides, drainage areas, etc. AHRI researchers, Dr Yaseen Khalil and Dr Mike Ashworth and others have confirmed the world’s most recent addition to the growing list of glyphosate resistant weeds: capeweed. |

Identification of the first glyphosate-resistant capeweed (Arctotheca calendula) population
Fri, 12 Feb 2021 This is the first confirmation of glyphosate resistance evolution in a capeweed population globally. With capeweed resistance already confirmed to photosystem-I inhibiting herbicides (paraquat and diquat), this study emphasizes the importance of using integrated measures that do not depend only on the use of non-selective herbicides for controlling herbicide resistance-prone capeweed populations. |
