Herbicide resistant hot-spots revealed in the most recent ryegrass survey
Chris Preston explains where the herbicide resistant hot-spots are for herbicide resistance in ryegrass and provides some sage advice around how to get the most out of old and new chemistries.
Can intercropping help with weed management?
This WeedSmart webinar outlines the principles of mixing different crops together, and how intercropping may provide weed management options for growers.
Dr Andrew Fletcher is a farming systems scientist at CSIRO who is passionate about the emerging role of diverse cropping systems. He is joined by WeedSmart southern extension agronomist, Greg Condon.
Topics covered include:
Characteristics of intercropping and companion cropping
Australian intercropping data
Canadian intercropping data
Implications for weed management
Examples of in-paddock applications
158: Regional Update – Peter McKenzie, Agronomist, Quirindi, NSW
Peter talks to us in this episode about how with there likely to be some difficulties in acquiring agricultural chemicals, it’s important to check in with what you need for your program down the track so you don’t get caught out.
He’s also got some great advice on summer weed control solutions for his region and gives a general overview of where people are at in and around his region in Quirindi, NSW.
Peter recently featured in one of our webinars on “What’s next for the north in weed control?” If you missed it, you can watch the recording here.
Peter Bach – Stripper front and chaff deck
Aiming for 130 per cent utilisation of their cropping land through the year, Peter and Kylie Bach have developed a farming system that extracts full value from barley stubble and minimises weed pressure.

Ask an Expert: What can I do at harvest to reduce my future weed burden?
Western Extension Agronomist Peter Newman fills us in on what people can do at harvest to reduce their future weed burden.
156: Regional Update – Alex Davies, Farmer, York, WA
We head to the Western Region in this episode and catch up with WA farmer, Alex Davies. Alex is based in York and has a continuous cropping farming system and also runs sheep.
Alex also shares with us his experience about how the last three seasons have gone with having a Harrington Seed Destructor and the positive impact it has had on helping in reducing weed burdens on his farm.

155: Why crop topping is a great tool to prevent weed seed set
It’s hard to believe that harvest is just around the corner! In light of this fast approaching reality, we wanted to talk about crop topping and spray topping.
Each of our WeedSmart Extension Agronomists provide a rundown on what to look out for in their cropping regions in regards to crop topping, swathing and desiccation.
WeedSmart Southern Extension Agronomist Greg Condon guest co-hosts for this podcast.
Paul McIntosh, Northern Region: crop topping or swathing/windrowing winter pulses, e.g. faba beans – jump to listen at 18:00
Jana Dixon, High Rainfall Zone: crop topping barley and spray topping pastures – jump to listen at 30:00
Chris Davey – desiccation and crop topping pulses – jump to listen at 41:30
Greg Condon – crop topping canola – jump to listen at 55:00
Dr Chris Preston, University of Adelaide, also joins us to explain the mode of action classification system changes from a letters system to numbers system and what it’ll mean for growers.
Dr Chris Preston explains the changes to MoA classification for herbicides in Australia from letters to numbers.

Mixed farming – does it really help control resistant weeds?
In this webinar, WeedSmart Southern extension agronomist Greg Condon looks at the mixed farming system and explains how the Big 6 principles encourage diverse weed management. Greg focuses on solutions in the medium rainfall zone whilst grower and agronomist Craig Drum focuses on the high rainfall zone.
Both Greg and Craig share real-life examples of clients who successfully controlled resistant weeds by using a mixed farming system, whilst remaining profitable.
Topics covered include:

153: Grazing resistant ryegrass key to weed control success for Scholz family
On this edition of the podcast, we’re focusing on controlling herbicide resistant ryegrass.
We’ll hear from grower Murray Scholz (pictured above), who is based in Culcairn, NSW. Murray and wife Emma are having a real win with grazing to keep ryegrass at bay.
We’ll also be hearing from University of Adelaide’s Dr Peter Boutsalis. Peter will provide an update on clethodim resistance and share some practical tips on how to keep on top of ryegrass.

Rod Birch on how the Big 6 is keeping weeds at bay at Catalina Farms
Catalina Farms is approximately 13,000 ha of 100% cropping, with 65% wheat, with the other 35% comprising of 20% canola and 15% lupins. The longterm rainfall is about 330ml per year and around 250-280ml of growing season rainfall.
Taking on a new property usually has its challenges, but there can be upsides too. Some of the challenges at Koobabbie were related to the fact it had been a livestock property and cropping machinery had never having been run through it. However, Rod explained that they have had some great news about the herbicides they are able to use.
Through the University of Western Australia’s resistance testing service, run by Dr Roberto Busi at AHRI, they found out some older chemistries were still effective, which was a pleasant surprise. Daniel Birch explains below in the Regional Update Podcast what they found out and how they used this information in their planning.
1:10 Crop rotations – Rod’s favourite rotation is Lupins – wheat – canola – wheat. It provides a lot of diversity for Modes of Action, as well as allows for nitrogen to go back into the soil through the lupin phase.
2:10 Crop Competition – the Birches are big fans of crop competition and it’s an essential part of their approach to controlling weeds.
3:00 Double knock – conditions haven’t been suitable for a double knock since 2016, but when the opportunity arises, it’s an important tool.
4:21 Mix and rotate herbicides – the crop rotations used at Catalina allow for really diverse chemical groups to be used, which is a great tactic to keep resistance at bay.
5:52 Stopping weed seed set – the Birches are trying to eliminate as many weeds in the crop as possible. Crop topping is a tool that they employ, as well as late spraying where necessary.
6:49 Harvest weed seed control – seed destruction is on the horizon at Catalina, but logistically has been a bit tricky.
7:21 Acquiring Koobabbie – it has been exciting for the Birches to be able to introduce more diverse rotations. They’ve been able to use Modes of Action which have never been used before.
9:48 Soil amelioration – liming has been a really beneficial tool for Catalina Farms. They also put out pot ash and gypsum. Deep ripping has also been a great tool to remove the compaction layer.
11:29 Big 6 benefits – controlling weeds is such an important strategy at Catalina Farms. Rod Birch said “We’ll never have a ceasefire on the war on weeds!”.
152: Regional Update – Daniel Birch, Catalina Farms, Coorow
We’ve had a bit of a break from the Regional Update as we were in Esperance for WeedSmart Week – but we’re back! This week we’re heading to the western region.
We hear from farmer Daniel Birch who is based near Coorow in Western Australia’s mid-west. Daniel recently took part in a resistance survey conducted by Australian Herbicide Resistance Initiative Researcher, Dr Roberto Busi. I caught up with Dan at the resistance workshop Roberto held in Dalwallinu a few weeks ago.
Dan explains what prompted him to get involved and how the results influenced his decision making on his farm.
