 Syngenta Growth Awards study tour to the UK and Switzerland | File Type: audio/mpeg | Duration: 00:28:43

This week we're catching up with two of the 2017 Syngenta Growth Awards winners. We were very proud that our Extension Agronomist Kirrily Condon nabbed the Adviser award in the Sustainability category. For Junee-based Kirrily, the goal is always the same. If she can provide advice that is making farming more profitable as well as sustainable, then she’s set out what she aimed to achieve. We also caught up with Duncan Young who farms out of Beverley in Western Australia with JT Young and Sons. He received the Grower award in the Sustainability category. Duncan has always been passionate about agriculture and practices sustainable farming. He's put a self-imposed ban on some chemicals in certain places next to a river, he uses technology like knife rollers over his paddocks instead of burning stubble and he has established a significant buffer on his property of up to 100m along the nearby Avon River. Each year, Syngenta profiles growers and farm advisers from different regions across Australia and New Zealand, showcasing their contribution in one of the following categories: Productivity: Recognises growers and advisers who use best practice in achieving consistent productivity gains. Sustainability: Recognises growers and advisers who are committed to addressing industry issues to create a sustainable and profitable future. Community & People: Recognises growers and advisers who make a leading contribution to their community, workers and fellow growers. Nominations for the Growth Awards are invite-only and 25 regional winners are chosen from the pool of nominees and announced in October. The regional winners attended The Growth Awards dinner last November and recently went on their study tour to the UK and Switzerland. The winners are chosen by an independent panel comprised of industry representatives and stakeholders. Join your host Jessica Strauss and guest co-host Greg Condon to find out about Kirrily and Duncan's approaches to agriculture and what they learned on their study tour.

 The unsung hero - crop competition | File Type: audio/mpeg | Duration: 00:37:10

We don’t want to give the weeds a free kick by growing un-competitive crops.  Crop competition with weeds is a double-edged sword. There is the effect of the weeds on the crop, and the effect of the crop on the weeds.  A competitive crop will suffer less yield loss at the hands of the weeds, and will also reduce seed set of the weeds compared to an un-competitive crop. In other words more crop, fewer weeds. In this week's podcast, AHRI Extension Agronomist Greg Condon and AgriVision Agronomy Consultant Matt Bissett provide excellent overviews on the different crop competition approaches that can be employed. There are six main aspects of crop competition: 1. Seed rate 2. Row spacing 3. Orientation (north-south vs. east-west) 4. Crop variety/species 5. Soil health 6. Time of sowing – early sowing is usually best It’s hard to get all of the six points above right, and growers need not aspire to practising all six of these competition factors, but they can use a range of these practices to ensure that their crops have a fighting chance against the weeds. So take a listen, as our regular hosts Jessica Strauss and Peter Newman take you on the crop comp journey!

 Blackgrass control in the UK and the pros and cons of paired rows | File Type: audio/mpeg | Duration: 00:35:33

We have two diverse topics for this week's podcast. Firstly we'll hear from Peter Aikman, who is a Mallee grain grower. He will share his experience on using the Rootboot for his paired rows, revealing the positive impacts and some of the negatives too. We also hear from Nuffield Scholar recipient Richard Hinchliffe. Richard is a grower and agronomist based in Yorkshire in the UK. By using a variety of diverse tactics, he's had a major win with controlling the very problematic weed blackgrass on his farming property. You're joined once again by your two co-hosts Jessica Strauss and Peter Newman.

 Herbicide degradation in dry soil and volunteer and ratoon cotton control | File Type: audio/mpeg | Duration: 00:30:26

With dry conditions in many parts of the country, we catch up with WANTFA Executive Director Dr David Minkey to find out if herbicides do in fact degrade in dry soil over time.

 Getting dry seeding right | File Type: audio/mpeg | Duration: 00:26:59

With many parts of the country facing little to no Autumn rainfall events so far, many growers are dry seeding. ConsultAg Agronomist Geoff 'Fos' Fosbery joins us in this podcast and provides some great tips on ensuring you get dry seeding right, including tips on herbicide application, such as trifluralin. We also hear from WA Farmer Kit Leake, who has been dry seeding for many seasons. He shares his insights and explains how he plans out his program well in advance. Music: bensound.com

 The future of robotics in broadacre ag and herbicide resistance in the US | File Type: audio/mpeg | Duration: 00:39:07

In this podcast, we learn about what's happening in the robotics space for broadacre agriculture from Professor Salah Sukkarieh, who is an international expert in the research, development and commercialisation of field robotic systems. Last year he won the 2017 CSIRO Eureka Prize for Leadership in Innovation and Science. We also hear from University of Illinois Crop Sciences Associate Professor, Aaron Hager. He gives us an update on how growers are dealing with herbicide resistance in the US and how metabolic resistance has been a real driver for change. He also shares what's happening in herbicide resistance research in the states. Take a listen! Music: bensound.com

 Pre-emergent herbicide application tips with Chris Preston & Heidi Gooden | File Type: audio/mpeg | Duration: 00:33:36

With seeding and pre-emergent herbicide application kicking off around the country, we got in touch a couple of herbicide application experts to share some timely advice on getting spraying right this season. Dr Chris Preston from the University of Adelaide gives a preview of his WeedSmart Webinar "Use pre-ems to maximise winter crops in the South", sharing valuable insights into management strategies around pre-em application and also gives us an update on the resistance levels to pre-ems. DeltaAg Agronomist and Consultant Heidi Gooden, who is based in Lockhart, runs us through the current dry spell conditions being experienced in the Southern Cropping Region and what impact this has on pre-em herbicide application. She also provides insights into knocking down lingering Summer weeds and more. As mentioned earlier, our first Webinar Series for 2018 is next week and features Mark Congreve from ICAN and Chris Preston from the University of Adelaide. Both experts will be joined by AHRI’s Peter Newman and will be discussing pre-emergent herbicide tactics in the North and South, respectively.

 Harvest seed destroying mill technology, with Ben White | File Type: audio/mpeg | Duration: 00:44:07

Harvest seed destroying mill technology has been the talk of the town among harvest weed seed control enthusiasts. For the podcast, we normally stick to seasonal issues, but in February, the Kondinin Group released a cracker Research Report, "Residue Management at Harvest". In this report, the Research Team (comprising of Ben White, Josh Giumelli and Mark Saunders), tested and reviewed a number of harvest weed seed control tools, including mill technology, which is the focus of this podcast. Jessica Strauss chats with Ben White about how mill technology works; the operational practicalities in the field; weed control; and mill wear issues. We also hear from two farmers who have invested in different branded mill machines, using them in both the 2016 and 2017 harvests. Farmers Roger Newman and Andrew Todd, both from WA, give candid insights into the pros and cons of their machinery thus far. Take a listen with your usual hosts, Peter Newman and Jessica Strauss!

 Disc seeding systems | File Type: audio/mpeg | Duration: 00:32:14

Nearly a year ago, Extension Officer Greg Condon co-hosted a podcast with Jessica Strauss on disc seeding and stripper front systems. It's a bit more of an obscure system, but it sure generated a lot of interest and is currently our most played episode, with more than 750 listens (you can check it out here: https://weedsmart.org.au/podcasts/disc-seeder-stripper-front-systems/). Given the interest, we thought we'd put together another podcast of similar ilk, but this time focusing on disc seeding itself.  In this podcast, you'll hear from Murry Scholz. He's based in Henty, NSW and has a John Deere, with a disc seeder on 7.5” rows. He's a mixed farmer and 2017 was his first year using the disc seeder. You may already be familiar with the Hatty family as they hosted growers on their farm for WeedSmart Week in 2017 and have been featured in podcasts and stories through WeedSmart. In this podcast, Stephen Hatty gives us some insight into his disc seeding operation. Stephen is based in Matong, NSW and has an NDF disc on 10” rows, on heavy clay soils. Like Murray, 2017 was the first year he used the disc seeding system. Take a listen. Music: bensound.com

 The importance of cleaning seed | File Type: audio/mpeg | Duration: 00:17:42

For many growers, planting seed is just around the corner, but to ensure quality seed is going in the ground, it's important to grade and clean it. In this podcast, we hear from seed cleaning contractor, David Bach who runs Toowoomba Grain and Storage. He explains the process of cleaning seed, why it's imperative and also provides some handy tips on grain storage. We also hear from Michael Meara who farms just south of Toowoomba in the Felton area. He shares a story about when he used a neighbour's seed when he ran out of his own and the consequences of that decision! You can find out further information about cleaning seed here: https://weedsmart.org.au/making-clean-seed-business/ Music: bensound.com

 Harvest Residue Topper (HRT) and Summer Weeds | File Type: audio/mpeg | Duration: 00:30:43

We're back for 2018! This is our first podcast of the year and we are excited to get into another year of informative and fun podcasts to ensure you have more crop and fewer weeds! Join your co-hosts Jessica Strauss and Peter Newman to delve into Summer weed management and learn about a mechanical weed tool - the Harvest Residue Topper (HRT). HRT developer Phil Bradley candidly discusses what lead him to build the HRT and provides a great explainer on how it works. We also hear from Bolgart farmer John Young who has been using his HRT for the last three harvests. He provides a good overview of the positives and drawbacks of using the HRT. Forbes-based Agronomist from Baker Ag Advantage, Chris Baker, gives us a rundown on the best management practice for Summer weed control. Take a listen! Music: bensound.com

 Cropping and Resistance Forum Overview | File Type: audio/mpeg | Duration: 00:30:01

In our last podcast for the year, we present an overview of the recent Cropping and Resistance 'Riders of the Storm' Forum which was supported by GRDC and hosted by AHRI and CCDM. There was a great turnout for the 3rd GRDC Crop Protection Forum which was held at Bunya Campus in December. For the past two decades, agronomic practices have dramatically improved the profitability of farming systems, however, there is a steady increase in weeds, disease and pests that threaten crop productivity. The Australian Herbicide Resistance Initiative (AHRI) partnered with the Centre for Crop & Disease Management (CCDM) to deliver key messages from their latest research. Senior researchers from AHRI, CCDM, University of Queensland, NSWDPI and more will gave their insights into how to control weeds, pests and disease, whilst also providing practical recommendations to maintain the efficacy of current practices. In this podcast, we hear from Northern Grower Alliance CEO Richard Daniel about manager wild oats in the North and Dr Lee Hickey about his work in developing new crop varieties using old genetics. We also get an insight into what agronomist Tony Lockrey from Moree, Queensland thought of the event, as well as event organiser Paul McIntosh. Music: bensound.com

 Summer fallow management and herbicide resistance in California | File Type: audio/mpeg | Duration: 00:24:45

This time of year, Summer fallow management is on the radar to ensure weeds are kept at bay and don't rob soil moisture and nitrogen from next year's crops. Ag Grow Director and Agronomist, Barry Haskins goes over some tips for getting summer fallow management right. Podcast co-host Peter Newman also discusses the importance of considering spray drift and how to avoid it. Later on, we hear from Brad Hanson who is a researcher at UC Davis in California. Brad talks about the challenges with resistance in orchards and vineyards in California with podcast host Jessica Strauss. The perennial crop industry in California is a diverse and high-value crop sector that is highly dependent on a relatively small set of herbicides. The challenges with glyphosate-resistant weeds in this crop sector differ considerably from those in broadacre crops and so do the opportunities.  Brad Hanson discusses the current status of resistance in the approximately 1.2 million hectares of tree, vine, and other perennial crops in the Mediterranean climate of California’s Central Valley. Because of the importance of glyphosate in this crops sector, glyphosate-resistance is the most widespread challenge.  However, emerging issues with resistance to glufosinate, paraquat, and the graminicides as well as changing production practices and weed control options suggest that research and education efforts remain a high priority.

 HWSC to tackle sclerotinia and the Australian Ground Spray Calculator | File Type: audio/mpeg | Duration: 00:21:26

Research out of the Centre for Crop and Disease Management (CCDM)has indicated that the harvest weed seed control tool (HWSC), narrow windrow burning, also help manage the damaging fungal disease sclerotinia stem rot. Kyran Brooks did his Honours in this research, with supervisors Mike Ashworth (AHRI) and Sarita Bennet (CCDM). The trials found providing temperatures were high enough and reasonably consistent (at least 350°C maintained for 10 seconds), sclerotinia was killed. An important finding was that sparse canola stubble that had not been windrowed was difficult to burn and could not achieve the temperatures required to kill sclerotinia. We also speak with research fellow Dr Chris O’Donnell from the School of Agriculture and Food Sciences at the University of Queensland. He explains how the Australian Ground Spray Calculator works. He'll be going into more detail about this at the 'Cropping and Resistance Forum' which will be held on December 6 in Dalby. You can get tickets here: www.ahri.uwa.edu.au/events If you'd like to receive a copy of the calculator before it's official launch, you can email Chris O'Donnell and request it: c.odonnell@uq.edu.au Music: bensound.com
