Spray application advice & precautions for 2,4-D use
Today on the podcast we get into the details on getting spray application right with expert, Bill Campbell (pictured above). We also get an insight into the MCPA LVE shortage and what considerations you need to make for alternative weed control solutions with Nufarm National Technical Lead, André Sabeeney. A handy guide on how to utilise water sensitive paper for spray coverage. Bill is based in Geraldton and is a spray application specialist. He provides some tips and how to get spray application right. As you’re probably aware, access to MCPA is in short supply, so there is a current warning to grain growers to be mindful that there could be damage caused to young cereal crops if 2,4-D is used as a direct replacement for MCPA LVEs. Nufarm National Technical Lead, André Sabeeney gets into the details of this. Nufarm National Technical Lead, André Sabeeney We also hosted a really great webinar last Friday – New chemistry – What’s new, what’s coming & how to keep them for longer with Greg Condon.

Getting mixing right to avoid glugs & efficacy issues
Today’s podcast focuses on getting tank mixes right to avoid glugs and ensure they’re as effective as they can be. Bayer Market Development Agronomy and Field Leader of Integrated Weed Management Australia, Craig White (who also has his own podcast here), talks to us about how to get mixing orders right to avoid glugs in tanks and to get the best tank-mix possible. We also hear about a new formulation of Sakura called Sakura Flow. Bayer Market Development Agronomy and Field Leader of Integrated Weed Management Australia, Craig White Nufarm Territory Manager for the Downs, Maranoa and South West Queensland, Malcolm Salisbury joins us on the podcast to provide an overview of some of the considerations that need to be made when mixing herbicides for the Northern Region. He also has some general tips on mixing too! Nufarm Territory Manager for the Downs, Maranoa and South West Queensland, Malcolm Salisbury We also talked about the new GRDC Common Weeds of Grain Cropping: The Ute Guide, which is available as a hard copy or digital manual, for the most key weeds impacting Australian farming systems. This national version replaces the former regional and seasonal weed ute guides. The new ute guide was a larger format and included descriptions and images of weed species through a range of growth stages. You can order your manual copy by ringing 1800 11 00 44 or emailing GroundCover We also talked about the webinar series we’ve been running. We are putting more webinars on at the moment to make up of the cancellations of in-person events. Our next webinar in this series is with Catherine Borger, looking at the biology of our most problematic weeds on Friday, May 29th. You can register here. You can also check out our latest webinar recording – WeedSmart in HRZ – practical options for dealing with ryegrass here. Handy links for getting mixing right Bayer Tank Mixing Guide GRDC National Variety Trials – Another point we couldn’t fit into the podcast Mal wanted to share was on crop herbicide tolerance. From the NVT guide it states: “Within many broadacre crop species, cultivars have been found to vary in sensitivity to commonly used herbicides and tank mixes, thereby resulting in potential grain yield loss, and hence reduced farm profit. With funding from GRDC and State Government Agencies across Australia, a series of cultivar by herbicide tolerance trials are conducted annually. The trials aim to provide grain growers and advisers with information on cultivar sensitivity to commonly used in-crop herbicides and tank mixes for a range of crop species.” Nufarm “Broadacre tank-mix guide”
Taking a closer look at Overwatch + post-em spraying tips
This week, we’re catching up with University of Adelaide weeds researcher, Dr Peter Boutsalis, to talk about the latest resistance testing results he’s collated, tips on post-em weed control and FMC’s new product, Overwatch. We’re also going to hear from FMC Australasia R&D Manager, Geoff Robertson, to get the rundown their new product, Overwatch. Overwatch has now received full registration in Australia and will be available for the 2021 winter crop season. This pre-emergent herbicide has shown to be effective at killing annual ryegrass, as well as other weeds such as silvergrass, sowthistle and more.

Companion and intercropping piquing interest of Aussie farmers
Today on the podcast we’re doing a special on intercropping and companion cropping. Canola + faba beans. (Photo: Greg Condon). Before we get into it, here’s what both intercrops and companion crops are: Intercrop: where two or more species are sown and harvested together with the objective to harvest the grain of both species. Companion crop: Where two or more species are sown together with the objective to harvest the grain of a single species. The other species are either grazed out or terminated using herbicides. We hear from CSIRO Farming Systems Scientist, Dr Andrew Fletcher. He tells us about the potential role of companion and intercropping in Australian grain farming systems. Andrew also recently presented this topic at the Perth GRDC Updates, which has sparked interest in this space in Australia. We also hear from farmer Murray Scholz, who has a mixed farming operation in the Southern Region in Culcairn NSW, which is halfway between Wagga Wagga and Albury. Murray has been on the podcast before, talking about his use of disc seeding. So, thanks to him for coming back! And finally, we hear from WeedSmart Southern Extension Agronomist, Greg Condon. He gives a detailed overview of companion and intercropping in his region and explains some of the quirks to how it all works. If you’re wanting to learn more about this topic, you can check out Dr Andrew Fletcher’s Perth GRDC Crop Updates paper here. If you’d like to check out what webinars we have coming up, including our Q&A Session on our Diversity Era Crop 101 Course this Friday, and our upcoming webinar in our series, The future of chemical use in farming with Mark Congreve click here.

Weed seed impact mill technology – where it’s at
It’s been almost two years to the day that we released our first podcast on weed seed impact mill technology. Back then, we caught up with WA (Cuballing) farmer, Roger Newman (pictured above) about his experience with the HSD and Andrew Todd (Dowerin, WA) about his experience with the Seed Terminator (check out the 2018 podcast here). Well, as you would know, there’s been lots of developments in the mill space, with Redekop and now TecFarm coming onto the scene with their own mills. In this podcast, Jessica Strauss is joined by guest co-host, agricultural engineer and Manager of Research and Development for the Kondinin Group, Ben White. Ben gives a comprehensive overview of where mill technology is at. We have interviews from farmers who are running different weed seed impact mills, including an update from Roger Newman, mentioned above; Dave Trewick from Elmore, Victoria, who has an HSD and Seed Terminator; Lyndon Bird from Goomalling, WA, who has a Redekop SCU; and Tom Lewis from Tecfarm who talks about the most recently released mill, the WeedHOG. Thanks to everyone for making this podcast possible!
Research is showing that mixing herbicides is the way to go
Join your co-hosts Jessica Strauss and Peter Newman to find out about why mixing and rotating herbicides is the way to go. Today we’re chatting with AHRI researcher Roberto Busi about his latest research into resistance in wild radish and annual ryegrass and why it’s so important to mix and rotate herbicides in your farming system. Peter Newman has this week also written AHRI insight on Roberto’s work which evaluates the mix and rotate message in more detail. You can check it out here. And if you were wondering what the ‘boxes’ were that were spoken about in this episode, check out the graphic below.
Surprising chaff lining results and the future of mill technology
In this week’s episode, Jessica Strauss and Peter Newman catch up in person to talk about the highlights of the GRDC Crop Updates which have been taking place across the country. Peter talks about what he presented at updates, including research done by Dr Michael Walsh from the University of Sydney on the efficacy of chaff lining. We also talk about research on weed seed mills and new machinery on the horizon. Pete also talks about his presentation on strip and disc systems and how they might fit into farming systems in WA. We also discuss the Weed Chipper, developed by Dr Andrew Guzzomi and Dr Carlo Peressini from UWA and researchers from the University of Sydney. The Weed Chipper now has a commercial partner in Precision Agronomics Australia. This project had received funding from the Grains Research and Development Corporation and was created in response to the growing concerns about herbicide resistance and the associated difficulties with fallow weed control. Director of McFadyen Ag Consulting and Northern Panel Chair Andrew McFadyen about the effects of the Summer rain the Northern region has received.
