  • Could oats be used to manage Fusarium crown rot?

    Could oats be used to manage Fusarium crown rot?

    A short study by NSW DPI, supported by GRDC, has found that it appears that oats could provide some benefit in reducing in-crop yield loss from Fusarium crown rot compared with other cereals within NSW farming systems. However, oats might not necessarily reduce paddock inoculum levels or, therefore, the Fusarium crown rot risk.

  • Three-pronged strategy to beat oat leaf blotch

    Three-pronged strategy to beat oat leaf blotch

    A three-pronged strategy is being deployed in a GRDC project led by the South Australian Research and Development Institute to provide a step change in breeding for Septoria leaf blotch resistance in oats. By better understanding the virulence and diversity of the fungus, identifying potential new sources of resistance in international germplasm sets and developing molecular markers to fast-track breeding efforts the project team is endeavouring to accelerate breeding progress for this economically significant disease.

  • GRDC ups ante in race to manage oat crown rust

    GRDC ups ante in race to manage oat crown rust

    Management of oat crown rust has always been challenging as populations of the fungus evolve rapidly. Control through the development and use of varieties with durable genetic resistance is the most economical and environmentally friendly method but progress has been slow. GRDC have upped the ante in the race to manage the disease through the deployment of new technologies, resources, and collaborations.

    Proactive fungicide management maintains disease-free crops

    Six leading agronomists share how their clients managed foliar diseases in 2022 and what to consider for 2023

  • Identifying pathotypes provides basis of rust control efforts

    Identifying pathotypes provides basis of rust control efforts

    Cereal rust pathotypes (aka races or strains) are isolates of rust that differ in their ability to overcome resistance genes in cereal varieties. Pathotypes are identified by using a sample of rust from a cereal crop to infect a set of cereal varieties (“differentials”) – each carrying a known resistance gene – and determining which resistance genes are overcome and which are not.

  • New resources a guide to fungicide management

    New resources a guide to fungicide management

    Three new videos from AFREN will help southern region growers improve their fungicide and fungal disease management.

    New chickpea IDM strategies tested

    Ascochyta blight of chickpeas is a serious fungal disease. A GRDC investment being conducted by the CSIRO is focusing on the Ascochyta infection life cycle in the hope of better informing out-of-season integrated disease management strategies.

    Blackleg management for 2023 begins now

    The successful defence against blackleg infection of canola requires continual vigilance. Even experienced growers need to remember that blackleg control relies on year-round integrated disease management (IDM), not just in-season fungicide use.

    Decade-old pathogen mystery solved via classical and new tools

    Australian-based researchers have cracked a decade-old cold case, identifying the pathogen responsible for the devastating faba bean gall disease, and thereby improving management strategies.
