    Sclerotinia transmission across a crop rotation

    How Sclerotinia moves from canola stubble into the whole of a farm’s crop rotation is under investigation in the northern and southern growing regions with the aim of learning how to manage or possibly break the disease cycle

  • Staying ahead of canola blackleg

    Staying ahead of canola blackleg

    Blackleg disease is constantly changing with respect to the effectiveness of genetic resistance and disease epidemiology – as well as through changes in stubble management

    Researchers issue warning on high disease pressure

    After a wet spring, researchers across Australia have warned that severe disease pressure will require proactive management to minimise damage to this year’s grain crops. Having a good integrated disease management strategy will be critical in reducing grain yield losses.

    Making sense of varietal responses to new rust pathotypes

    Knowing the presence of resistance genes in a variety is important in predicting and explaining how a variety will perform if and when a new rust pathotype appears. This is well illustrated by the events that unfolded following the introduction of wheat stripe rust pathotype 198, which originated from either Europe or South America.

  • Wheat powdery mildew pathogen now resistant to two fungicide groups

    Wheat powdery mildew pathogen now resistant to two fungicide groups

    With wheat powdery mildew capable of reducing grain yields by up to 25 per cent in conducive seasons, a fungicide resistance expert calls for care to preserve the life of available pesticides

  • Fighting back against the chickpea scourge

    Fighting back against the chickpea scourge

    An upgrade in the ability to protect chickpea crops from Ascochyta blight (Ascochyta rabiei) is being engineered through five research programs that are working in lockstep to overcome key disease control limitations

  • 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
