Disc seeding systems

Nearly a year ago, WeedSmart 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). 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.   Murray Scholz This picture shows Murray’s John Deere single disc unit.   Even crop establishment between two different wheat varieties and wheat maturity on 7.5 inch rows at Murray’s farm in 2017 (disc seeding).

The importance of cleaning seed

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.

Cropping and Resistance Forum Overview

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 managing wild oats in the North and Dr Lee Hickey about his work in developing new crop varieties using old genetics. Lee talks about Vavilov wheats, speed breeding and a root gene! We also get an insight into what agronomist Tony Lockrey from Moree, Queensland thought of the event, as well as event organiser Paul McIntosh. Dr Lee Hickey is working on a number of projects, including ‘speed breeding’. Music: bensound.com

Summer fallow management and herbicide resistance in California

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. Take a listen!

NWB to tackle sclerotinia and the Australian Ground Spray Calculator

Research out of the Centre for Crop and Disease Management (CCDM), in collaboration with AHRI, and co-supported by the GRDC, has indicated that the harvest weed seed control tool (HWSC), narrow windrow burning, also helped to manage the damaging fungal disease sclerotinia stem rot. Kyran Brooks, who is now an agronomist at Landmark in WA, 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. You can find out more about sclerotinia stem rot by checking out the GRDC fact sheet on it here. 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. 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 The Australian Ground Spray Calculator The Australian Ground Spray Calculator is nearly ready for release. Below is an example of how it works in practice.   In the picture above, you can see the parameters (nozzle manufacturer, nozzle type, nozzle orifice, pressure, tank mix, etc) are filled in, as an example. The blue box on the right-hand side then becomes populated with details about the spray quality, drift potential and more. Music: bensound.com

Autonomous farm machinery from Dot Tech Corp and spray drift tips

It’s that time of year already where farmers are getting out their spray rigs and dealing with in-crop weeds. While it is a busy time of year, it’s essential to ensure you’re across good spraying technique to ensure spray drift does not occur. Spray drift expert Mary O’Brien explains wind inversions and provides tips for avoiding spray drift. You can find out more about Mary’s workshops on spray techniques through her website here. You can also follow her on Twitter at @spraydriftgirl Spray drift expert Mary O’Brien While listening to advice can be really helpful, seeing it with your own eyes is hard to beat. Check out Mary’s video below demonstrating the effects of wind inversions on spray droplets. You can also check out the GRDC’s latest factsheet on pre-harvest herbicide application here. GRDC also have a detailed spray application manual you can access here. Autonomous farm machinery is the topic of the moment. The possibilities to do seem endless, but how far away are some of these machines away from hitting Australian shores? Cory Beaujot from DOT Tech Corp says it might be sooner than you think. He gives us a detailed insight into this family business making autonomous farm machinery out of Saskatchewan in Canada. Some of the benefits the company says you’ll see with using their Dot Power Platform (which can be used as a seeding rig and more) are a reduction in costs for fuel, labour and equipment. If you’d like to see more details about the company and its autonomous machinery, check out their website here. The Dot Power Platform (seedotrun.com) We also talked about the Crop Protection Forum coming up in Dalby on December 6. You can check out more information and purchase tickets here.
