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.

Mixing herbicides wins again
Tue, 15 Oct 2019 What sort of person goes to a cocktail party and sticks strictly to beer? A smart one! We all know that mixing drinks can hurt the next day. We can’t say the same for herbicide mixing though. The smart farmers and agronomists are mixing two or more herbicides targeting the same resistant weed to delay resistance and maximise weed control, and the science is supporting this approach. AHRI researcher Roberto Busi is a long-term advocate of herbicide mixing and in his recent paper which describes some computer modelling that he undertook with the help of Michael Renton. |

Rotations and mixtures of soil-applied herbicides delay resistance
Tue, 10 Sep 2019 Weed resistance to foliar herbicides has dramatically increased worldwide in the last two decades. As a consequence, current practices of weed management have changed, with increased adoption of soil-applied herbicides to restore control of herbicide-resistant weeds. We foresee metabolism-based resistance and cross-resistance to soil-applied herbicides as a potential global consequence to the increased and widespread adoption of new and old soil-applied herbicides. |
