In this episode of Regional Update, we're joined by Angus Roberts, a young grower from Dandaragan, WA. Angus chats to host Shannon about his mixed farming operation 160km north of Perth and their history with clethodim resistance. 
Since attending Mildura WeedSmart Week in 2022, Angus and his family have aimed to adopt all of the Big 6 strategies to lower their weed seed bank and prevent herbicide resistance. Angus is now a WeedSmart fan and convinced 20 of his mates to join him at WeedSmart Week in Geraldton last year!

This Beyond Resistance podcast episode featuring experts Richard Holzknecht and Jeshua Smith from VICCHEM is an essential resource for farmers and agronomists looking to optimise their herbicide mix in the tank and ensure every drop counts.  Since spray water typically makes up more than 95% of what goes into a spray tank, the quality of that water dictates whether a "chemistry experiment" succeeds or fails in the paddock.  Our speakers explain how common issues like hard water, high pH, and bicarbonates can tie up active ingredients—such as glyphosate and clethodim—before they even have a chance to work. 
By listening to this deep dive, you will learn why "plants don't drink rocks" and how poor water quality can lead to sublethal doses, which inadvertently accelerates the development of herbicide resistance. 
This podcast provides practical, field-ready advice on how to transition from reactive troubleshooting to proactive water management.  
Listeners can gain insights into the benefits of different water sources, the necessity of regular water testing, and the strategic use of conditioning agents like liquid ammonium sulfate (AMS) and citric acid to ameliorate quality issues. Also discussed is how to distinguish between genuine chemical resistance and spray failures caused by poor water, potentially saving growers from unnecessary and costly management changes. Whether you are an agronomist seeking to refine your recommendations or a grower aiming to maximise return on investment and protect the longevity of your chemical tools, this episode offers the technical expertise needed to stay ahead of the curve.

In this episode of Regional Update, we hear from Kate Shooter, an agronomist at McGregor Gourlay based in Toowoomba. Kate shares how conditions are progressing in the Eastern and Western Downs regions of Queensland, particularly in the wake of last November’s hailstorm. 
With mung bean planting in full swing and sorghum crops just coming into head, Kate also flags barnyard grass, feathertop grass, milk thistle and fleabane as the region’s current priorities for weed control. Tune in to this episode to hear Kate’s advice on staying ahead of resistance and getting on top of summer grasses.

In this episode of Regional Update, we hear from Reece Rayson, who continues to make the best out of a couple of below average rainfall seasons, with an eye on the WeedSmart Big 6 to lead the challenge on herbicide resistance.   
Reece attended WeedSmart Week 2025 in Geraldton this year, and highlights some of the common factors discussed and incorporated into their own system, from chemical fallow, pre-em controls, and fenceline management.  Building a robust rotation, addressing soil constraints, along with mixing herbicides are some of the key takeaways to keep herbicide resistance on the boundary to maintain flexibility within the years were rainfall does prove a challenge. 
 When in the thick of a weather-affected harvest on a less than best season, keeping an eye on the end-game is important to be ready for the next season and next challenges ahead.  Whether it be delayed starts to sowing or summer weeds germinating during harvest, having a plan from the Big 6 could help set you up for successful weed management. 
Tune in to hear first-hand what a couple of WeedSmart Weeks can do for your system’s thinking and keep ahead of the curve!

 In this episode of Beyond Resistance, we hear from our WeedSmart Extension Agronomists from the Western and Southern regions on steps to take from this point in the season with cool soft spring finish to the winter growing season and points to think about when considering harvest operations and planning the next season of weed control.  
Pete Newman will highlight a few gems of research and on-farm practices to remember when dealing with this long growing season in the Western region.  
Greg Condon speaks to the weed control options to consider across a range of on-farm situations for the Southern growing region going into the clean-up phase of the 2025 season.
