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.

Video breakdown

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.

149: Boundary mapping and soil amelioration changed the game for Esperance farming family

On this edition of the podcast, we’re providing a preview on our WeedSmart Week in Esperance event, which is now only two weeks away!
We hear from Beaumont farmers, Phil Longmire, and son Tom. Tom will be presenting at WeedSmart Week, providing a farmer experience on the forum day.
Phil, Bindy and Tom Longmire run a family farming business based in Beaumont, 110 km ENE of Esperance in a 425-450mm rainfall zone.
Soil amelioration and boundary mapping are just some of the approaches which have really helped them win the war against weeds.
We also  catch up with Andrew Messina. Late last year we caught up with Andrew about the trials for Bilberry’s spot spraying technology which took place on his farm. He is going to give us an update and a preview of what he’s going to share on the Innovation Panel at WeedSmart Week Esperance.
News
We’ve got a new article on advances made in weed recognition technologies. In this article we look at how blanket spraying of herbicides in low weed density situations could become a thing of the past in Australia as new weed recognition technologies enable site-specific weed control in-crop. Dr Michael Walsh from University of Sydney provides comment. Read it here.
You can also check out our latest webinar recording ‘What’s next in the North for weed control?’
Peter McKenzie, agronomist with Agricultural Consulting & Extension Services, and Angus Dalgliesh, grower and agronomist with Nutrien Ag Solutions, join WeedSmart Northern Extension agronomist Paul McIntosh to discuss some of the weed challenges their clients have been experiencing in the North, and some of the weed management tactics they’ve been using to deal with these challenges.
WeedSmart Week 
We’ve got a great program lined up for Esperance WeedSmart Week. This event really is about farmers talking to farmers, as we’ve heard from our guests today and at the event, we really get to explore that in more detail.
The 3-day program consists of a Forum Day at the Esperance Civic Centre with day 2 and 3 consisting of farm visits in the Esperance region to see how forward-thinking growers are implementing the WeedSmart Big 6 tactics to minimise the impact of herbicide resistance on their businesses.
You can get your tickets here.

145: Farmers can now help improve green on green technology

On this edition of the podcast, we’re looking at how farmers can now actively become citizen scientists by improving weed recognition for machine learning.
University of Sydney Precision Weed Control PhD student, Guy Coleman earlier this year, along with Dr Michael Walsh hosted a workshop on weed recognition and machine learning in Wagga Wagga.
Guy walks us through the key learnings presented at this workshop and also reveals details about a new open source weed locator his team is releasing.
