  • GRDC in Conversation: Brad Egan
    In this episode of GRDC In Conversation, host Oli Le Lievre sits down with Brad Egan, a forward-thinking grain grower from Esperance, Western Australia. Brad shares insights into the evolution of his family farm, the challenges of farming in a changing climate, and how data-driven decision-making is helping to improve productivity despite declining rainfall.  From using drones to optimise spraying efficiency to a long-term soil amelioration project that has transformed low-performing soils into some of the best on the farm, Brad discusses the power of innovation in agriculture. He also highlights the importance of precision agriculture, farm data management, and the role of technology in the future of farming.  Additionally, Brad talks about his involvement in supplying barley to Lucky Bay Brewery, bringing local produce to craft beer, and the potential of AI and automation in shaping the next generation of Australian farming.    GRDC in Conversation is a limited series GRDC Podcast.

  • Green on green case study: Precision weed management
    Precision weed management is where optical sensors and remote and sensor weed mapping systems are used to target weeds and therefore cut herbicide costs. The technology is becoming more widely available, which is why GRDC is investing in a series of case studies, to explore the benefits and costs related to these technologies. With green on brown systems, weeds can be detected in a fallow field. And now there's also green on green technology, which uses an algorithm to differentiate between weeds and crops. Tim Rethus operates a zero till cropping business in Horsham in Victoria's Wimmera region. Tim's invested in both green on brown and green on green technology. We caught up with Tim to find out more about his decision to integrate these systems into his farming practices, and whether he thinks the return on investment has been worth it.  Contact: Tim Rethus, Grower  [email protected]    More in Precision weed management series:   Video, Green on green case study  Podcast, Green on brown case study  Video, Green on brown case study  Podcast, Drone weed mapping case study  Video, Drone weed mapping case study    Project Investment Code: SRE2310-001SAX  Learn more about your ad choices.

  • Strategies to manage turnip yellows virus
    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  [email protected]    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.

  • GRDC in Conversation: Callum Wesley
    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.
