GRDC Podcast

As many southern growers know, good growing conditions for crops also means good ground conditions for slugs. After favourable springs in both 2020 and 2021, slug populations are on the rise and sliding into regions that don’t normally see them. As Dr Michael Nash explains, it’s about being proactive, understanding the risk factors and making informed management choices for the different species....

Dual-purpose crops under irrigation offer an attractive graze and grain return. But what's the best set-up to maximise potential at the paddock level? In this GRDC podcast, we hear from three growers who put forward paddocks in an ambitious effort to answer just that, as part of the Optimising Irrigated Grains investment. Contact Kate Coffey Riverine Plains kate@riverineplains.org.au More informat...

Weed seeds and herbicide resistant genes have the potential to move across farm boundaries and between different land uses. A collaborative project, called area wide management for cropping systems weeds, is taking a unique approach to traditional weed control by collaborating beyond fence lines with varying land users across three pilot regions - the Sunraysia, the Darling Downs and the Murrumbid...

Across Western Australia’s grain growing regions, farmers are reporting increased mouse activity, sparking new concern about risks heading into the 2022 season. To help growers keep ahead of this issue, the CSIRO’s Steve Henry and Dr Wendy Ruscoe delivered GRDC mouse control workshops over 21 locations and 4 days across WA’s grain belt in March, speaking with 245 growers and advisers. In this podc...

The main summer grain crop in the northern grains region, sorghum is ordinarily planted between September and January. But for the past two years, scientists from the Queensland Alliance for Agriculture and Food Innovation at the University of Queensland have been trailing sowing the summer crop in winter. And while the trials have taken place in cool conditions, the results have proved to be red...

For the first time ever, a national survey on herbicide resistance has been conducted as part of a GRDC investment. As Dr Peter Boutsalis from the University of Adelaide explains, there's good news on the resistance status of annual ryegrass to pre-emergent herbicides. Contact Dr Peter Boutsalis The University of Adelaide peter.boutsalis@adelaide.edu.au More information Annual ryegrass weed manage...

2022 is likely to be a high-risk year for rust, based on the widespread distribution of rust in 2020 and 2021 and the wet summer. Dr Grant Hollaway from Agriculture Victoria and Professor Robert Park from the University of Sydney share all the details on the latest variety disease ratings and recommendations to help growers make informed stripe rust management decisions this season. Contact: Dr Gr...

Perth Update Event 2022 – Dr. Mike Ashworth The cost of constantly evolving weed infestations in Australia is staggering. Growers spend around $2.5 billion every year on the problem, with annual ryegrass the number one ranking Australian cropping system weed. In WA, a series of trials over several years has been studying the interaction between wheat seeding timing and pre emergent herbicides choi...

Grain storage is a long-term investment so it’s important to get it right from the start. Considerations need to include storage design and structural integrity, effective pressure testing and knowing how to seal silos correctly to achieve successful fumigation. Manufactures are a good source of information, but make sure they’re not your onlysource. And that’s where GRDC’sGrain Storage Extension...

The Seed of Gold is one of the grains industry’s most prestigious awards. First presented in 2007 only four people have received this honour. The latest recipient is globally recognised research scientist Emeritus professor Stephen Powles from Western Australia who was presented with his Seed of Gold in 2021. The award is given in recognition of an individual’s outstanding contribution, dedication...

It’s an unusual thing to see – a mob of cattle grazing contentedly in a patch of paddock, held there by an invisible border. But virtual fencing technology is really taking offand is showing promise as a tool to help mixed farmers control weeds. On Heath Nickolls’ cattle and grain property near Pinnaroo in the South Australian mallee, the CSIRO’s Dr Rick Llewellyn is leading a GRDC and Australian...

Nick Poole from FAR Australia provides an excellent explanation of how to target fungicide applications for the best economic return. He describes the value of focusing on critical growth stages and their ‘money leaves’, the best way to manage disease risk in crops before tillering, and the importance of protecting fungicide effectiveness for the long term.

It’s been common practise across the southern grain growing region to wait for opening rains, before applying a knockdown herbicide, then seeding the crop. But new research is revealing weedsare better controlled by adopting a three-pronged approach of sowing early, at a high density crop seeding rate while also applying an efficient herbicide. As the University of Adelaide’s Dr Gurjeet Gill and B...

While farmers typically spray fungicide to manage one disease, applications should be considered in a broader context. Dr Steven Simpfendorfer describes how spraying one pathogen can inadvertently encourage resistance in other pathogens that may be present. He outlines some typical examples, including rusts and powdery mildew in wheat; blackleg and sclerotinia in canola; as well as net blotches an...

The start of 2021 has seen widespread waterlogging in the Great Southern and Esperance regions. Sub-surface drainage, one of many water management options, is not widely adopted, for reasons that will be better understood during this project, with surveys used to understand current grower practice and opinions. Sub-surface drainage, one of many water management options, is not widely adopted, for...

The seedbank is the link between the current weed populations and future infestations. While the seedbank life is well understood for major weed species such as annual ryegrass, new research has filled the knowledge gap on the seedbank life of emerging weed species.

In Western Australia’s South West agricultural zone there are 3 million hectares of lateritic gravels or ironstone gravel soils. These are sandy soils that have a cemented laterite surface or caprock. Many growers are using contractors with specialised machinery that rips and pulverises this top-layer, making sowing easier and improving the likelihood of good crop establishment. What is also neede...

When Western Australian Ag Research Company TrialCo signed on with GRDC to run a trial on non-wetting sandy soils in low rainfall country the last thing anyone expected was a wet start to the growing season. In this podcast TrialCo field operations manager and TrialCo’s executive officer outline the reasons for the trial and the methodology applied to evaluate the use of surfactants in sandy non-w...

Innovative lab technology has helped uncover new information on the water and nutrient use efficiency of ironstone gravel soils. It's a first for the grains industry and a big step forward in managing this often-underperforming soil type. As Murdoch University’s Dr Fran Brailsford explains, the process of discovery involved analysing more than 400 gravel samples from across Australia’s growing reg...

Generous rain and high prices have increased the economic risk from Sclerotinia and blackleg of canola this season. Dr Steve Marcroft outlines the very real risk of fungicide resistance developing in blackleg of canola in Australia – and how growers can achieve sustainable disease control.
