In this episode of Beyond Resistance, we're joined by herbicide resistance researchers Roberto Busi (DPIRD WA, The University of Western Australia) and Peter Boutsalis (Plant Science Consulting, Adelaide University) for a run-down of their latest resistance testing results.
This episode covers some of the fundamentals of herbicide resistance; what it actually is, how it happens, how to take a 'good' test, and what a positive result means for on-farm weed control decisions. 
Roberto and Peter also share some of the findings from their latest research on glufosinate, clethodim and ammonium sulphate, and discuss what the APVMA's paraquat decision will mean for growers using 'quat products in summer weed control programs.

*This episode of Beyond Resistance was recorded on 11 June, 2026, before the APVMA announced new restrictions for the use of paraquat and diquat products.*
In this episode of Beyond Resistance, we're joined by our own Northern Extension Agronomist, Paul McIntosh, and GRDC's Manager of Chemical Regulations, Gordon Cumming.
Australia has one of the most trusted chemical regulatory frameworks in the world and in this podcast, we aim to de-mystify how the maximum residue limit (MRL) system underpins our access to global markets. 
Gordon and Paul discuss how growers can stay on the right side of the regulations, and the unfortunate reality of what happens if an Aussie shipment doesn't comply with overseas restrictions. 
Ultimately, it all comes down to communication; read the herbicide labels, talk with your marketer before putting a crop in, and use all of the Big 6 strategies! We can all play a part in preserving Australia's hard-won reputation as a supplier of safe and high-quality food, while also protecting the efficacy of our available herbicides.

In this episode of Regional Update we're joined by Rolleston grower, Kurt Mayne. Kurt's main crop is usually chickpeas, although he also rotates through mungbeans, sorghum and barley.
Kurt's a big believer in using every tool in the Big 6 toolbox for weed control. In addition to crop rotation, he also aims for zero weed seed set and uses harvest weed seed control.
He's currently got a self-propelled sprayer, two tow-behind sprayers and chaff decks on his header. This year he also experimented with swathing his mungbeans for the first time. Tune in to find out how it went!

In this episode of Beyond Resistance, we're joined by Adama Market Development Managers, Bevan Addison (WA) and Andre Sabeeney (SA), to discuss how this year's unusual seasonal dynamics and fuel/fertiliser issues are altering regional crop rotations and weed control. 
Our guests unpack why maximizing weed control during pulse and canola phases is essential for driving down grass weed seed banks before returning to cereals, as well as the strategic value of mixing and rotating chemistry to protect herbicides for future seasons. Product choice is just one part of the equation!
So, if you're weighing up herbicide options in pulses, reviewing your pre-em program or looking to get more out of your post-em applications, this episode is for you!

In this episode of Regional Update, we're joined by Joe Koch, a grower from the Flinders Ranges in South Australia.
Joe and his family run a mixed "crops and chops" operation in separate high and low rainfall zones. With a rare wet start (200ml from the end of March - April!) under their belts, they've been faced with higher numbers of ryegrass, barley grass, marshmallow weed, capeweed and milk thistle!
Joe has been keeping busy on the boomspray, getting in some double-knocks as well as narrow windrow burning. With a bit of imi and glyphosate resistance starting to creep into the region, he's also a big proponent of diverse cropping and mixing and rotating herbicides.
Tune in to also hear his reasoning behind their latest purchase - a new green-on-brown sprayer!
