Australian Herbicide Resistance Initiative (AHRI)



AHRI Snapshots is a podcast which provides info on what we do at AHRI

Our researchers work out of the University of Western Australia, next to the beautiful Swan River in WA’s capital, Perth.

Trifluralin resistance explained with Stephen Powles

This podcast looks at trifluralin resistance, with AHRI Director Stephen Powles. The results out of a recent AHRI, entitled Novel Tubulin Mutations Conferring Resistance to Dinitroaniline Herbicides in Lolium rigidum are the primary focus.


Professor Martin Vila-Aiub explains fitness penalties and farming in Argentina

In this podcast, we chat with Professor Martin Vila-Aiub, who is currently on sabbatical at AHRI from the University of Buenos Aires. As you’ll learn in more detail, in his sabbatical period at AHRI, he will write a review on the impact of resistance endowing mutations on plant fitness. We also hear from Martin about the differences in farming between Argentina and Australia and we talk conceptually about what would happen if there were more fitness penalties.


Herbicide resistance survey results overview

Every five years, Mechelle Owen, one of our dedicated AHRI researchers, undertakes the massive task of visiting 500 fields in Western Australia just before harvest to sample seeds of surviving weeds for resistance testing with GRDC support. So far, we have reported on the results from the latest survey in AHRI insight, looking at ryegrass resistance. You can check it out here. In this podcast, Mechelle gives an overview of her results so far. We’ll be publishing further podcasts and blog posts on Mechelle’s research as the data is analysed and published.


Professor Baruch Rubin commentates on night spraying and Israeli farming systems

Professor Baruch Rubin

AHRI was recently lucky enough to be visited by Professor Baruch Rubin from the Hebrew University of Jerusalem. Baruch completed a sabbatical in AHRI 15 years ago, so we were delighted to welcome him back for his short visit. In this podcast, Baruch commentates on night spraying and sheds light on some of his research in this area. He also gives insights into how farming systems in Israel compare to those in Australia.


Crop Ecologist Dr Richard Smith discusses farming systems

Richard Smith

In this podcast, Jessica Strauss chats with Dr Richard Smith, who is an Associate Professor of Cropping Systems Ecology and Management at the University of New Hampshire and currently on sabbatical leave at AHRI. They discuss the difference in farming systems between Australia and the US and more! Take a listen.


Plant fitness and resistance explained

This podcast with AHRI Principal Research Fellow Dr Qin Yu focuses on explaining some of the more tricky aspects of the paper: “A double EPSPS gene mutation endowing glyphosate resistance shows a remarkably high resistance cost”. This paper was a collaboration between AHRI researchers Heping Han, Qin Yu, and Steve Powles, as well as past AHRI researchers Adam Jalaludin and Martin Vila-Aiub.
