  Western Australia Department of Primary Industries and Regional Development research officer Catherine Borger and project participant, Ben Whisson from Consult Ag (pictured above) have some interesting preliminary results to share with us. DPIRD’s Catherine Borger Barley Project Learn more about the project described in the podcast here. Weed Seed Wizard Check out the Weed Seed Wizard tool here. Barley Grass RIM Barley Grass RIM came about through the GRDC-funded ‘Maintaining profitable farming systems with retained stubble’ initiative that included an objective of promoting pro-active weed management strategies. Barley grass has become a critical ‘driver’ weed in several grain growing districts under no-till systems and in some areas such as Upper Eyre Peninsula, with barley grass also having a big influence on the cropping system. Using the RIM approach to testing the best IWM strategies has been valuable for ryegrass management over a long period, so it was an obvious step to provide agronomists, farmers and researchers with a RIM tool for these other major grass weeds. You can access the Barley Grass RIM tool here. You can learn more about both the Barley and Brome modelling tools here as well.

  Back in February and March of 2020 Tim had some summer rain and decided to look at the weeds not the temperature. If the weeds weren’t moisture stressed he kept spraying all day even when it was hot. He had some great results which we’ll get into in this podcast. We’ll also be hearing from Nufarm’s André Sabeeney and Mitch Allen about their new product Terrad’or. Terrad’or is a new Group G herbicide from Nufarm. This product is best partnered with glyphosate as a knockdown spike or mixed with paraquat for double knock application. Spray Application Manual The GRDC has published an excellent spraying manual you can access. This Spray Application GrowNotes™ manual provides information on how various spraying systems and components work, along with those factors that the operator should consider to ensure the sprayer is operating to its full potential. This manual focuses on issues that will assist in maintaining the accuracy of the sprayer output while improving the efficiency and safety of spraying operations. It contains many useful tips for your spray operations. The manual includes information on sprayer set-up, including self-propelled sprayers, new tools for determining sprayer outputs, suggestions for assessing spray coverage in the field, improving droplet capture by the target, drift-reducing equipment and techniques, the effects of adjuvant and nozzle type on drift potential, and surface temperature inversion research.

New content Our latest Ask an Expert is “How can I maximise grass weed control using hybrid canola?” EPAG Research agronomist, Andrew Ware answers the question and says the results of six years of trial work across the southern growing region with GRDC investment has demonstrated how important crop nutrition and time of sowing are for maximising canola vigour and yield. Read it here. Also, don’t miss our latest Case Study on Single family, Coonamble NSW. Tony and Sharon Single farm with Tony’s parents John and Mary, south east of Coonamble in northern NSW with views of the Warrumbungle Range. Across the 4500 ha cropping area at ‘Narratigah’, the weed numbers are low as a result of the Single’s ‘farming moisture’ philosophy, which involves planting whenever there is sufficient subsoil moisture to establish a competitive crop on their heavy clay soils. Read it here.

With many parts of South Australia experiencing a dry start, independent Agronomist, Craig Davis talks to us about the challenges with controlling weeds and volunteer crops in his patch.

With so many new products hitting the market and plenty more in the pipeline, it’s beneficial to find out the details about these new products and how they might fit into farming systems.
