    Disease tool to inform growers’ variety choices

    A project is developing a ‘yield loss to disease’ tool that draws on five years of Australian field trial data and statistical analysis. The tool will be used to determine likely yield responses to various disease loads for wheat varieties with different resistance and tolerance ratings.

  • ‘FR-5’ podcast series a roadmap for fungicide resistance management

    ‘FR-5’ podcast series a roadmap for fungicide resistance management

    A new GRDC podcast series aims to help growers understand how fungicide resistance develops and how they can prevent it from becoming an issue in their cropping programs.

  • Grasses offer important clues on cereal rust pathogens

    Grasses offer important clues on cereal rust pathogens

    News reports on COVID-19 over the past 18 months have, at times, made reference to the field of epidemiology – the study of the distribution and causes of diseases in populations. Epidemiology is also vital in plant disease control – for example, delaying epidemic onset and slowing disease progress (‘flattening the curve’) are critical in dampening the epidemic potential of a plant pathogen.

    Gene editing holds promise for climate-proofing cereal breeding programs

    Scientists at the University of Queensland believe that gene editing will play a vital role in climate-proofing crops to ensure food security into the future.

  • Keeping canola ahead of evolving blackleg

    Keeping canola ahead of evolving blackleg

    Shifts in the efficacy of genetic resistance to blackleg and changing farm practices mean staying ahead of this evolving pathogen takes constant vigilance. Both early sowing and stubble retention practices have an impact on infection patterns and management practices.

  • Suppressing disease to protect break crops
    Diseases, 13 May 2021
    Suppressing disease to protect break crops

    GRDC is targeting profitable disease management in pulses and oilseeds through active disease surveillance and diagnostics, pathogen biology, epidemiology (how diseases function in the environment), genetic solutions and the development of integrated disease management packages.

  • Summer crop disease breakthroughs
    Diseases, 07 May 2021
    Summer crop disease breakthroughs

    For the first time, researchers in Queensland have identified an insect vector for phytoplasma in grain legumes. They have also discovered asymptomatic host crops for Fusarium wilt in mungbeans and quantified the interaction with root lesion nematode.

  • Australian approach needed for Sclerotinia
    Diseases, 06 May 2021
    Australian approach needed for Sclerotinia

    Researchers are targeting sources of genetic resistance to Sclerotinia stem rot in canola germplasm. Management solutions tailored to Australian conditions are also being investigated.

  • DNA tests sharpen decision-making

    DNA tests sharpen decision-making

    DNA testing is now providing new insights that will help identify diseases causing pathogens and understand more about their behaviour and spread. The same technology is also behind a breakthrough that will see a commercial test for rhizobium rolled out to growers and researchers in 2021.

  • Broadleaf rise adds to disease profile
    Diseases, 03 May 2021
    Broadleaf rise adds to disease profile

    Viruses and Sclerotinia are two disease threats that have come under increased scrutiny in New South Wales in recent years. Both can easily fly under the radar with symptoms that are often indistinguishable from those caused by abiotic stress and herbicides.
