    GRDC webinar: Fall armyworm management tips and tactics

    The Grains Research and Development Corporation (GRDC) is hosting a timely webinar this Friday, February 23, to address the surge in fall armyworm (FAW) infestations affecting sorghum crops across the northern grain growing region. At 9 AM AEST (QLD) / 10 AM AEDT (NSW), the free event will feature Dr. Melina Miles from Queensland Department of Agriculture and Fisheries and Dr. Joe Eyre from the Queensland Alliance for Agriculture and Food Innovation, alongside Nutrien agronomist Ross Pomroy. They will share their expertise on managing FAW, with a focus on developing economic control thresholds, yield loss predictions, and effective management practices for sorghum and maize. The webinar aims to equip growers and agronomists with the latest research and practical advice on early decision-making, ecological-friendly strategies, and evolving management techniques to combat this invasive pest. Rebecca Raymond, GRDC's grower relations manager, highlights the webinar as an invaluable opportunity for growers to gain expert advice on navigating the complexities of FAW management, ensuring economic efficiency and crop sustainability.

    Unpacking pest’s flower fascination helps build defensive strategies

    Understanding why pigeon peas are so susceptible to Helicoverpa armigera is the first step in building crop defences and boosting summer crop options for northern growers. Research scientist Trevor Volp is building a greater understanding of this behaviour and identifying potential crop defence traits.

    Common misunderstandings surround phosphine fumigation

    Powered fumigation recirculation boxes for large silos aim to allow phosphine to be applied at ground level and distribute gas through the storage more evenly. Recirculation can also be achieved safely and effectively by still applying the phosphine in the storage headspace and using a small fan plumbed between the headspace and base of the silo to recirculate gas.

    The experienced scientist is urging growers and agronomists to monitor crops for RWA, and use the RWA action threshold calculator, to help determine the cost effectiveness of chemical treatment.

  • Strategy a part of managing snails after liming

    Strategy a part of managing snails after liming

    Some growers have noticed snail numbers increase after liming. Lime is a source of calcium which increases shell strength and fertility. As a result of this observation, a small research trial was conducted to gauge the impact liming had on snail fertility and shell strength, and whether incorporating lime or using a different type of lime could limit snail population growth.
