Australian Herbicide Resistance Initiative (AHRI)



AHRI Snapshots is a podcast which provides info on what we do at AHRI, as well as updates on weeds research from across the country and internationally.

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

Cinmethylin controls multiple herbicide resistant ryegrass

In this edition of AHIR Snapshots, AHRI researcher Dr Roberto Busi is helping us to understand new products before they come to market. He recently investigated the product Cinmethylin which is a new BASF product called Luximax. He found that Cinmethylin controls multiple resistant ryegrass, among other helpful things which we’ll get into in this podcast.


Herbicide mixtures & crop competition – with Facundo Cortese

Today we’re catching up with Facundo Cortese who has been working out of AHRI alongside Roberto Busi. He recently spoke at the Perth GRDC Crop Updates on how herbicide mixtures and crop competition provide excellent control of annual ryegrass and mitigate herbicide resistance.


Weed and seed biology and ecology research

In this week’s podcast, we catch up with visiting scholar, Aniruddha Maity, also known as Maity. He’s working on the seed biology and ecology of brome, wild barley, wild oat and ryegrass and connecting them with their herbicide resistance. Maity is originally from India and is a PhD candidate at Texas A&M University (@TAMU on Twitter). He’s come to AHRI with the Endeavour Leadership Program.


Group H (HPPD) resistant wild radish explained

The first resistance to HPPD, also known as Group H, herbicides in wild radish has now been discovered by AHRI researchers led by PhD candidate Huan Lu. Wild radish is just the third weed in the world to evolve resistance to this group of herbicides. In this podcast, we caught up with Huan to learn more about the results published in his paper “Evolution of resistance to HPPD-inhibiting herbicides in a wild radish population via enhanced herbicide metabolism”.


What would it be like farming without glyphosate?

For the first AHRI Snapshots podcast of 2020, we caught up with Associate Professor Ken Flower about a recent paper he co-authored with AHRI Director Hugh Beckie and AHRI’s Agronomy Lead, Mike Ashworth. With glyphosate currently under intense scrutiny worldwide from an environmental and health perspective, the authors of the paper “Farming without glyphosate” contemplated possible scenarios of farming without our most important and popular herbicide.


Ground cover is king when it comes to pre-emergent herbicide efficacy


In our final AHRI Snapshots podcast for 2019, we caught up with AHRI’s Dr Yaseen Khalil about his papers the “Effect of crop residues on interception and activity of prosulfocarb, pyroxasulfone, and trifluralin” and “Pyroxasulfone efficacy for annual ryegrass control is affected by wheat residue height, amount and orientation”.
