    Finding strategies to preserve disease resistance

    While genetic resistance is a highly effective way to manage crop disease, such resistances can be easily overcome by pathogen evolution. Modelling of management options has identified opportunities to reduce selection pressure and preserve the effectiveness of resistance.

  • Weigh up canola Blackleg risk before sowing
    Diseases, 01 Mar 2021
    Weigh up canola Blackleg risk before sowing

    Plant pathologists are encouraging canola growers to think about their Blackleg risks and how crops will be protected ahead of sowing

  • New tool measures disease resistance impact
    Diseases, 27 Feb 2021
    New tool measures disease resistance impact

    A new tool is set to help growers and advisers better understand the potential yield loss associated with different levels of partial resistance in cereal diseases.

  • Accurate diagnosis essential for disease control
    Diseases, 25 Feb 2021
    Accurate diagnosis essential for disease control

    The NSW Department of Primary Industries’ cereal diagnostic service ensures accurate in-crop identification of diseases and other abiotic constraints. The results support the implementation of appropriate management strategies and provide an insight into seasonal variation and trends.

  • Overcoming durum’s Achilles heel
    Diseases, 24 Feb 2021
    Overcoming durum’s Achilles heel

    Durum wheat often commands a premium price, but its vulnerability to crown rot can make it a more risky option to bread wheat. New pre-breeding lines with the promise of better yields are being tested in national trials.

  • Eyespot resistance in sight
    Diseases, 20 Feb 2021
    Eyespot resistance in sight

    A new screening technique which allows researchers to easily compare eyespot resistance in cereals looks set to allow growers and breeders to identify varieties with better resistance.

  • Crown rot solutions pour into wheat breeding pipeline
    Diseases, 18 Feb 2021
    Crown rot solutions pour into wheat breeding pipeline

    While traditional sources of resistance and tolerance to Fusarium crown rot in wheat are limited, detailed genetic analysis and pre-breeding efforts have now yielded more than 70 wheat lines with superior disease robustness.

  • Gene pool for yellow spot resistance expands
    Diseases, 16 Feb 2021
    Gene pool for yellow spot resistance expands

    Genetic resistance is one of the key tools to manage yellow spot in wheat. Research has now identified multiple new resistance genes for progression into Australian breeding programs, and has better quantified potential yield losses.

  • Typing a solution to barley foliar diseases
    Diseases, 15 Feb 2021
    Typing a solution to barley foliar diseases

    Resistant varieties provide the most effective way to manage foliar diseases of barley such as powdery mildew, net form net blotch and spot blotch. Pathotype monitoring and ongoing identification of new sources of resistance is essential to stay ahead of pathogen evolution.

  • AFREN support network to tackle fungicide resistance
    Diseases, 14 Feb 2021
    AFREN support network to tackle fungicide resistance

    Fungicide resistance has been detected in diseases of wheat, barley and canola across all growing regions. Now, with support from Australian Fungicide Resistance Extension Network, growers have more capacity to manage and prevent its occurrence.
