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.

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”.

World’s first case of metabolism-based glyphosate resistance

Today on AHRI Snapshots, we catch up with Colorado State University Associate Professor, Dr Todd Gaines about metabolism-based glyphosate resistance. Peter Newman recently wrote AHRI insight on this topic. Back in 2011, then Ord River agronomist, Andrew Cripps, was approached by a farmer asking why his Barnyard grass had survived glyphosate. Dr Todd Gaines and Professor Steve Powles visited the northern irrigation region, took samples, and confirmed glyphosate resistance. Recently, further research at AHRI by Chinese researcher Dr Pan Lang, under the direction of AHRI’s Qin Yu, confirmed the world’s first case of metabolism-based glyphosate resistance. Todd shares his experience…


Crop Protection Forum preview

Cesar is partnering with the Australian Herbicide Resistance Initiative (AHRI) and the Centre for Crop and Disease Management (CCDM) to deliver the 2019 Crop Protection Forum. Attendees will learn about the latest research into insecticide, herbicide and fungicide resistance affecting the grains industry. Take a listen to this podcast with Cesar’s Jessica Lye and AHRI’s Hugh Beckie to find out more about the forum.


Do plants pay a fitness cost to be resistant to glyphosate?

Today we catch up with AHRI’s Dr Qin Yu about the paper “Do plants pay a fitness cost to be resistant to glyphosate?” This paper was published earlier this year and is written by Martin Vila-Aiub, Qin Yu and Steve Powles. This paper reviewed the literature to understand the effects of glyphosate resistance on plant fitness as the molecular, biochemical and physiological levels.


What are canola’s super-powers?

In this podcast, Cindy Benjamin catches up with Charles Sturt University (CSU) Professor Leslie Weston to get the next instalment on their work. The last podcast with Leslie focused on cereals, while this one looks at the mechanisms at play in canola. Leslie led a large project at CSU alongside Associate Professor Dr Chris Preston at The University of Adelaide, to investigate several aspects of crop competition. PhD candidate James Mwendwa and the project team conducted field trials at Wagga Wagga comparing the weed-suppressive effect of six hybrid and one open-pollinated canola cultivars, both in-crop and post-harvest, in 2014.
