In Australian canola crops, turnip yellows virus is the one of the most widespread and economically damaging viruses, and over the past decade, epidemics have commonly occurred in different regions causing considerable losses.   Turnip yellows virus is particularly challenging to manage because it is transmitted by green peach aphid and needs just a few aphids per plant to cause substantial spread.  A GRDC investment led by the Department of Primary Industries and Regional Development in Western Australia has been looking at management options and developed new data and guidelines around seed treatments and foliar insecticides.  In this episode, we’re joined by senior research scientist Ben Congdon to find out more.  Contact:  Ben Congdon, DPIRD  benjamin.congdon@dpird.wa.gov.au    More information:   Turnip yellows virus and its vector, the green peach aphid, in canola: the 2024 epidemic in southern New South Wales and management options Green peach aphid - best management practice guide    Project Codes:   DAW2305-003RTX Learn more about your ad choices.

In this episode of GRDC In Conversation, host Oli Le Lievre sits down with Callum Wesley, a third-generation farmer from Southern Cross, WA. They discuss Callum’s innovative approach to farming in a low-rainfall zone and his journey collaborating with researchers that has led to a nationwide research project which could revolutionise seeding strategies for dryland farmers across Australia. Callum shares his journey from working in agricultural research to returning home and implementing cutting-edge techniques that maximise water use efficiency and improve productivity in challenging conditions.   More information GRDC in Conversation is a limited series GRDC Podcast.

GRDC, CSIRO and University of South Australia have done a lot of work on how to deal with the sandy soil situation. Hot off the back of a huge investment, culminating in a series of workshops in 2023, they're scaling up, taking the machines and expertise to more than 20 farms across the southern region. It's a project with a great deal of grower involvement and targeted to making that sandy stuff work for growers, not against them. In this podcast we speak to CSIRO research team leader, Therese McBeath and South Australian grower Andrew Thomas.  Contact: Therese McBeath, CSIRO therese.mcbeath@csiro.au    More  Information: Practical guidelines for sustained productivity in sandy soils     Project Investment Code: CSP2403-017RTX  Learn more about your ad choices.

A passion for pulses and in particular a love of lentils has inspired the career of research scientist Dr Audrey Delahunty. Growers are already benefiting from Dr Delahunty’s research into genetic solutions for heat tolerance in lentils, and now she's extending into frost quality technology and other pulses. Meantime, Dr Delahunty is also the recipient of this year’s GRDC “Emerging Leader Award” in the South.     Contact: Dr Audrey Delahunty audrey.j.delahunty@agriculture.vic.gov.au  More  Information:   Victorian agronomist and scientist each win grains award  GRDC awards   Learn more about your ad choices.

Gemma Walker is a mover and shaker in the Western Australian grains industry, literally! If she isn’t moving from a board meeting in one city to the next, she’s flying back home to the family sheep and wool property in Munglinup. Gemma is at the forefront of WA’s ag industry, promoting sustainable practices for the future as well as getting her hands dirty on the farm. In this episode of GRDC In Conversation, host Oli Le Lievre speaks with Gemma about her passion for the grains industry. The conversation explores the importance of innovation, community and leadership in agriculture, as well as the value of collaboration across different industries. Gemma emphasises the need for nurturing the next generation of leaders and the significance of vulnerability in leadership roles.  GRDC in Conversation is a limited series GRDC Podcast.

Sclerotinia stem rot is a canola disease that is challenging to manage using rotation due to the wide range of crops that play host to the fungus that causes it. Since there are no Australian canola cultivars with sclerotinia resistance, the disease is usually managed with preventative fungicide sprays at flowering. However, fungicides can be costly, and their return on investment is difficult to predict.   In an ideal world, Australian growers would have access to canola cultivars with resistance to sclerotinia stem rot. And that’s exactly what researchers at the Centre for Crop and Disease Management (CCDM), a co-investment of GRDC and Curtin, are trying to develop. In this episode, we’re joined by Senior Research Fellow and Project Lead, Mark Derbyshire, to find out how.

Precision weed management is where optical sensors and remote and sensor weed mapping systems are used to target weeds and therefore cut herbicide costs. GRDC is investing in a series of case studies to explore the benefits and costs related to precision weed management technologies. One of those case studies is Warakirri Cropping, one of Australia's largest grain growers with 11 cropping farms across New South Wales, Queensland, Victoria and Western Australia. We chat to a few of the Warakirri team, including Junior Assistant Farm Manager, Patrick Anderson, Farm Manager, Jono Robinson, Southern Regional Manager, John Stevenson and Warakirri Cropping's Sustainability Officer, Jess Sleigh. Contacts:           Jess Sleigh, Sustainability Officer, Jessica.Sleigh@warakirricropping.com.au John Stevenson, Farm Manager John.Stevenson@warakirricropping.com.au   Watch the video: https://youtu.be/AleO-NRv5EM   Project Investment Code:           SRE2310-001SAX Learn more about your ad choices.

Ray Harrington has always had an eye on the battle taking place in the fields of Aussie agriculture, the war on weeds and pests. So, he and a group of like-minded farmers, researchers and innovators took up the torch to solve it once and for all. In this episode of GRDC’s In Conversation, host Oli Le Lievre speaks with Ray about his journey to inventing the Harrington Seed Destructor, one of the most effective tools in dealing with weed resistance in the market. In their chat, they cover the significant issues facing farmers today including weed management, herbicide resistance, declining rural communities and succession. Ray insists the key is for the next generation to have a plan for the future, and he shares the significance of community in farming life. Please be advised that today's conversation includes more colourful language than usual, which may be inappropriate for some listeners.   GRDC Project Code: HAG2308-001SAX GRDC in Conversation is a limited series GRDC Podcast.

Sclerotinia in lupin is a sporadic disease found across the WA grainbelt. When weather conditions favour disease spread, it can cause significant loss of yield and grain quality.   With GRDC investment, collaborative research by the Department of Primary Industries and Regional Development, the Centre for Crop and Disease Management, and the Mingenew-Irwin Group has been looking at ways lupin growers can learn to recognise risky scenarios and employ management strategies to reduce impact of the disease.  To find out what the team has discovered, we’re joined on this episode by DPIRD research scientist Ciara Beard.   Contact:  Ciara Beard  Research Scientist, DPIRD  ciara.beard@dpird.wa.gov.au    More information:  Sclerotinia management in WA’s lupin crops   Lupin sclerotinia disease risk assessment guide  SclerotiniaCM - Sclerotinia Management App     Project Codes:  DAW2104-002RTX  Learn more about your ad choices.

A GRDC National Grower Network investment, based in Western Australia, has been working to improve knowledge of fallow management and the economic value of fallows in cropping rotations. Through this project, it has been identified that there are four key objectives growers should take into account when considering fallow – profitability, moisture, weeds, and nitrogen. In this episode, Laconik founder Darren Hughes explains that by understanding these objectives, growers will be in the best place to understand the most profitable fallow strategies they should consider this year.
