Episode 258: Area wide management for cropping systems weeds

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 Murrumbidgee irrigation area. area wide management, weeds, cropping, systems, management, economic, opportunity

Episode 257: Mouse control in Western Australia

Across Western Australia’s grain growing regions, farmers are reporting increased mouse activity, sparking new concern about risks heading into the 2022 season. grdc, research, csiro, mouse, mice, management, risk, growers, control, workshops

Episode 256: Beat the heat with late winter sown sorghum

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 hot. grdc, research, development, cropping, sowing, sorghum, trials,

Episode 253: Getting the upper hand on annual ryegrass this season

In WA, a series of trials over several years has been studying the interaction between wheat seeding timing and pre emergent herbicides choice on annual ryegrass seed production, with some helpful results on offer. grdc, research, weeds, growers, ryegrass, cropping, trials, seeding, herbicides, resistance, canola

Episode 251: Grain storage

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 Projectcan help. In this podcastnational extension team member Ben White takes youthrough the latest evolution in Silo features and pressure testing methods. grains storage, ben white, grain storage, stored grain, grain storage extension project, pressure testing methods, on-farm storage, storage, management, Chris Warrick

Episode 250: Seed of Gold – Emeritus Professor Stephen Powles

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 and commitment to communicating research outcomes to the Australian grains industry. seed of gold, award, learning and development, innovation, stephen powles

Episode 249: The invisible fenceline – how virtual fencing is reshaping weed control

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 off and 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 Wool Innovation investment trialling virtual fencing to gain better crop integrated weed management. As Rick and Heath explain, a strip grazing trial of 40 Angus heifersis delivering promising results. Heath Nickolls, cattle grazing, Rick Llewellyn, crop protection, weeds pests diseases, innovation

Episode 248: Applying fungicides for economic return with Nick Poole

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.

Episode 247: Triple threat – the three-pronged approach to tackling weeds

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 Ben Fleet explain, the mid-trial results come from a five-year GRDC investment looking into weed management across a range of rainfall zones in SA, Vic and WA. weeds, crop protection, weeds pests diseases, Gurjeet Gill, Ben Fleet, weed management, herbicide

Episode 246: Fungicide risk factors with Dr Steven Simpfendorfer

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 and powdery mildew in barley. fungicide resistance, disease, weeds pests diseases, crop protection, Steven Simpfendorfer, blackleg, sclerotinia, net blotches, powdery mildew, barley

Episode 245: Rising interest in sub-surface drainage

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 reasons that will be better understood during this project, with surveys used to understand current grower practice and opinions. In total, the GRDC invests about $2 million nationally in projects addressing waterlogging, with work ranging from the new sub-surface drainage projects through to genetic research. waterlogging, agronomy, Philip Honey, Mark Preston, sub-surface drainage
