Summary: Welcome to the hub of the WeedSmart Podcast! Each fortnight we'll whip around the cropping regions focusing on weed control and issues which have cropped up (pun intended). Your hosts, Jessica Strauss and Peter Newman will be poking fun at themselves and each other. We look forward to giving you a snappy, informative update from the comfort of your tractor, ute, or wherever you may be on the road or farm. Producer: Jessica Strauss Hosts: Jessica Strauss and Peter Newman Intro music credit for podcasts prior to June 2018: www.bensound.com
Herbicide mixes are not all one of the same. The efficacy of a mix can be affected significantly by the adjuvant its mixed with. On this podcast we chat with Research Agronomist with Jubilee Consulting, Andrew Somervaille. He explains herbicide mixes in more detail, with a particular emphasis on glyphosate. South Australian Independent Consultant, Craig Davis also talks about herbicide mixes and shares what advice he gives his clients in this regard. We also talk to Tim Rethus. He's an innovative farmer who will be presenting at the upcoming WeedSmart Week in Horsham. He farms with his brother Luke, father Geoff and long-time worker Glenn. His farm, near Horsham in the Wimmera is a 100% dryland winter cropping enterprise, receiving 425mm annual rainfall with around 3/4 of that rain falling during the growing season. In this interview, we get a snapshot of the farming system Tim and his family has adopted on their farm, as well as some guidance on how to make innovate decisions for your farming enterprise. Take a listen!
We're excited to officially launch the ticket sales for not one, but two WeedSmart Week events in 2019 in this podcast. Our extension agronomists join us this week to provide overviews of our events in both Emerald and Horsham in August. An event which is just around the corner though is the Australian Local Government Association Conference where one of the topics will be roadside weeds. This is taking place from June 16-19. Andrew Storrie 'Agronomo' joins us on the podcast to explain how roadside weeds can directly impact farmers and provides some options for effectively controlling them. Take a listen!
Soil compaction is an issue farmers face in regions across the country, however, there are some unique differences between management approaches in the Western/Southern regions, compared to the Northern region. In this podcast, we chat with Department of Primary Industries and Regional Development WA Agricultural Development Officer, Bindi Isbister, who is based in Geraldton, WA, to get a Western/Southern perspective. Agronomy professional & crop nutrition specialist, Bede O’Mara, gives us the Northern perspective. He works at Incitec Pivot Fertilisers in Toowoomba. Soil compaction leads to aeration issues and reduced water infiltration rates. This impacts negatively on a crop as its roots have less access to water and nitrogen. Compacted areas reduce water movement and decrease plant growth, leading to a less competitive crop and potentially more weeds. Take a listen to the podcast to learn how to prevent soil compaction and how to deal with it if you do have compacted soils.
This week on the podcast, we look into how to utilise weather forecasts and get the latest information on crop competition trials conducted by YP AG. Agriculture Victoria Seasonal Risk Agronomist Dale Grey provides an excellent overview of what weather forecasts to take seriously and those which you should probably take with a grain of salt. Dale has a real knack for simplifying this complicated topic, so if you want to get a good overview of the weather, he's your man! Dale refers to no breaking rains yet in the interview but since the interview, there have been some breaking rains across parts of southeast Australia. You can check out the latest map for May rain thus far here: http://www.bom.gov.au/web03/ncc/www/awap/rainfall/totals/cmonth/colour/latest.hres.gif. Also on related climate topics, the 'Climatedogs' animations (key climate drivers)were updated for a national audience recently and you can check them out here: http://www.climatekelpie.com.au/index.php/climatedogs/. And if you'd like to keep up-to-date with all of Dale's weather forecasting, you can simply hit a button to subscribe to The Break here: http://agriculture.vic.gov.au/agriculture/weather-and-climate/newsletters. We're also excited to have Agriservices Agronomist Chris Davey on this podcast talking about crop competition at seeding time. Chris is based in Kadina, South Australia and he recently wrote a great article in YP AG’s agronomy newsletter, where he said ‘weed seed reduction starts at seeding’. There are multiple benefits of crop competition, including increasing crop yield in weedy situations, reducing weed seed set, and improving the efficacy of Harvest Weed Seed Control. Chris has kindly given us access to his article if you'd like to refer back to it after the interview on the results from YP AG's recent trials and some tips on crop competition.

Did you know you can bale your chaff dumps? South Australian farmer Andrew Ridgway, who is based in Pine Hill, has baled his chaff dumps this year to provide additional feed for stock in his area. Andrew tweeted about this novel way of managing chaff dumps, so we followed up with him to find out more about the process. We also caught up with WA farmer Rod Messina about how he's managing his dumps this year. Rod also talks to us about his recent trip over east where he was introduced to strip and disc farming systems. He talks about how some elements of the system could potentially be applied in WA farming systems.
Technology in agriculture is rapidly evolving and being adopted by farmers in Australia. In this podcast, we catch up with the University of Sydney Associate Professor and Director of Weed Research Dr Michael Walsh to find out what his recent test results were on the vertical iHSD. He looked at the efficacy of the machine killing weed seeds and also looked at the effectiveness of the kill rate as the harvester increased its speed. We also caught up with Dalby Rural Supplies Precision Ag Specialist Jeremy Jones to find out more about the WEEDit and how it's performing in the marketplace. He also shares with us what ag tech has got him excited! Join your co-hosts Jessica Strauss and Peter Newman to learn more!
Our new free course is here! In this podcast, you'll hear from your co-hosts Jessica Strauss and Peter Newman, who are joined by course presenters, Dr Chris Preston and Mark Congreve. WeedSmart Content Creator Cindy Benjamin also provides an update on what's new on the WeedSmart website. Pre-emergent Herbicides 101 will take you through the in’s and out’s of pre-emergent herbicides. The course is taught by Dr Chris Preston (Uni of Adelaide) and Mr Mark Congreve (ICAN)and the course covers why pre-emergent herbicides are an important tool in Australian cropping systems and how pre-emergents help you to manage herbicide resistance in crop weeds. (Especially in a world where 11 of the 17 modes of action have documented resistance.) If you're an agronomist and you'd like to deepen your understanding of how pre-emergent herbicides work (in both winter and summer cropping systems), this is the course for you! You can register for the course (for free!) here: http://www.diversityera.com/courses/pre-emergent-herbicides-101 Mark Congreve also chatted about workshops he's running on effective use of pre-ems. You can get all the details here: https://t.co/wZFqXZxh9v
In our last podcast we heard from weed seed impact mill company representatives, so this week we're hearing from farmers on the ground and finding out about how they faired over harvest with both the Seed Terminator and iHSD. Farmers Kim Slarke and Scott Walton both share their experiences. We also hear from WeedSmart Southern Extension Agronomist Greg Condon on what he has been presenting at GRDC Updates this year. He gives an overview of the benefits of crop competition and diverse rotations, as well as providing an overview of some of the hot topics at Updates this year. Join your co-hosts Jessica Strauss and Peter Newman and take a listen.
We're so excited to be back for 2019! This is our first podcast for the year and we look at how both the Seed Terminator and iHSD fared over harvest. Seed Terminator research and development director Dr Nick Berry gives insights into how the Seed Terminator went and talks about new models which are now available. McIntosh and Son Katanning branch manager Devon Gilmour tells us about how the iHSD went and talks about the now commercially available vertical mechanical iHSD. We also hear from DPIRD's Research Officer Catherine Borger about the benefits of lime application on crop-weed competition. Your hosts are Jessica Strauss and Peter Newman.
On the last podcast for 2018, we spoke with Dr Haydn Kuchel, who is CEO & Head of Breeding at AGT Breeding. AGT Breeding develops new field crop varieties. Haydn talks to us about AGT-run crop competition trials and how they influenced their breeding programs. We also learn about crop varieties coming online in the future. Finally, we checked in with AHRI and WeedSmart extension agronomist, Greg Condon. He gives an overview of crop sequencing and rotation, as well as providing some tips on post-harvest spraying.
Would you like to know more about the changes to 2,4-D regulations? Nufarm Technical Marketing Lead André Sabeeney joins us on the podcast to give an overview. He also shares some more broad advice on spray drift. We’re also joined by Professor John Thompson from the Centre for Crop Health based at the University of Southern Queensland. He talks to us about beneficial fungi and its impact on crop growth. The benefits for crop growth occur when the beneficial fungus is in combined with the crop root. This is called Vesicular Arbuscular Mycorrhiza. It previously was referred to as VAM and now more commonly AMF. A lack of AMF can result in poor early crop growth and therefore poor crop competition with weeds. We also learn more about a similar effect of root-lesion nematodes causing poor growth of intolerant wheat varieties and poor weed suppression. Join your hosts Jessica Strauss and Peter Newman and take a listen!
We have a special guest co-host this week, with Planfarm Agronomist Dani Whyte joining Jessica Strauss, providing insights on farmer interviews she conducted last harvest. Dani has been working on a GRDC RCSN project, looking at harvest weed seed control practices in the Kwinana East port zone. She conducted 10 farmer interviews in total. In this podcast, we hear from three of the farmers who participated in the project. Farmers Clint Della Bosca, Stephen Dolton and Ty Kirby all share their HWSC experiences. The focus of this project is getting the weeds in the front of the header in low yielding crops. The core messages are: - Harvest low – 10-15cm (this means paddocks need to be clean of rocks/stumps and staff need to be trained accordingly) - Coreflute attached to finger tyne reel - Knife extensions/crop lifters on the front of the harvester. Take a listen to learn more.
In the podcast this week, we focus on crop topping and the relatively new herbicide, Sharpen. In our last podcast, Andrew Messina talked to us about Case IH harvester set-up. This week farmer Lance Turner gives us the rundown on John Deere gear. AHRI and WeedSmart Agronomist Greg Condon talks to us about the benefits of crop topping and what to do if you suspect you’ve got herbicide resistance. We also hear from BASF Technical Services Manager, Phil Hoult, about the herbicide Sharpen. It’s now registered as a harvest aid in winter pulses, for winter cleaning of Lucerne and for wild radish seed-set control in winter cereals, so we’ll find out in more detail about its applications for broadacre croppers.
In the podcast this week, we’re focusing on harvester set-up and we also discuss how to capture weed seeds in the chaff fraction. John Broster from CSU gives some insight into the research on capturing weed seeds which was done by himself and Michael Walsh from Sydney University. A few years back, they measured how many weed seeds were entering the chaff fraction in a modern harvester. We also hear from WA farmer Andrew Messina about setting up Case harvesters. Finally, with the terrible drought conditions in Queensland and NSW, many farmers have had to source feed from totally different parts of the country. We chat with Grains Farm Biosecurity Officer for Biosecurity Queensland Kym McIntyre about the implications.
In this podcast, we’re focusing on research and ideas out of the 21st Australasian Weeds Conference. WeedSmart's Jessica Strauss was lucky enough to attend and caught up with a number of researchers who presented. The AWC is a biennial conference and carries on a long tradition of bringing the weed management community together to discuss new developments and share information about cutting-edge and best weed management practices. The conference attracts more than 250 delegates from across Australasia and globally. In this podcast, we hear from Professor Antonio DiTommaso from Cornell University. He was the International Keynote Speaker and spoke on the topic “Climate Change and Weed Migration: What do we know and what next?” Dr Michael Widderick, who is the Principal Research Scientist at the Queensland Department of Agriculture and Fisheries also presented. He spoke on “Research priorities for weed suppression by crops in Australia” Last, but not least, we hear from Dr Cheryl McCarthy. She’s a Research Fellow at the Centre for Agricultural Engineering at the University of Southern Queensland. She spoke on “Machine Vision Systems for Robotic Weed Sensing in Real World Commercial Environments”.
