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. Director of McFadyen Ag Consulting and Northern Panel Chair Andrew McFadyen *In the podcast we chat about presentations which were stand-outs. We didn’t give the full name for ‘Keith’ – his full name is Keith Norman and he is a UK Farm Management Specialist. We also talked about the model on HWSC Pete developed so you can calculate the cost of different HWSC options on your farm. You can download the model here.
Green on green technology set to be within reach
Technology in general, including in the ag space, is moving forward at an accelerated rate. While green on brown technology is now being adopted and good results are being seen in the field, green on green technology is on the cusp of being a commercial reality. And while there might be fears it’ll be cost-prohibitive, AutoWeed Systems Engineer who is a guest on the podcast this week, says that the technology will be comparable and in some cases cheaper than the green on brown tech available today. Alex Olsen demonstrating the Autoweed at WeedSmart Week in Emerald 2019 The University of Sydney’s weed researchers Dr Michael Walsh and Guy Coleman recently ran a workshop with delegates from all over the world looking at how to make machine learning more accessible for green on green technology by making open source libraries of broadacre weeds and crops available to anyone who might want to access them, including companies working on making this tech a reality. WeedSmart’s Southern Extension Agronomist Greg Condon provides us with an overview of how the workshop ran and what he presented in on in terms of how this tech might fit into different farming systems. Join your co-hosts Jessica Strauss and Peter Newman and learn more! John Stevenson from Warakirri Lockhart explaining to delegates how important the Weedit camera spraying is for their business.
Summer cropping tips for the Northern region and highlights from Agritechnica
We’re back for our first podcast of 2020 and the decade! Join your hosts, Jessica Strauss and Peter Newman, as they talk about Summer Cropping and highlights from the massive agricultural tradeshow, Agritechnica. With recent rainfall in parts of the Northern region, some farmers will be considering putting in a Summer crop. We catch up with our Northern Extension Agronomist, Paul McIntosh for a broad overview on this, as well as, Agricultural Consulting and Extension Services Agronomist, Peter McKenzie. Peter provides some insights into how to control weed burdens and get the best possible yield outcome for crops in these tough drought conditions. We also catch up with Rabobank Agricultural Analyst Wes Lefroy (pictured left, above) about his trip to Germany where he went to Agritechnica. Automation was a big focus in 2019 and Wes gives his perspective on how that technology will fit into Australian cropping systems. Wes also appears on the Rabobank podcast. Check it out here.
