    Dashboard tracks rising Ascochyta aggression

    With the number of highly aggressive Ascochyta rabiei isolates on the rise, Griffith University researchers are investigating why, and they have developed an online dashboard to help

    Socio-economic factors will drive blotch management practice change

    Growers face multiple risks in their farming business. In the face of fungicide resistance risk, a recent survey has found that the socio-economic impact of fungicide resistance remains a dominant factor driving net blotch management practice change. Using this information Curtin University’s Centre for Crop and Disease Management is developing methods to effect greater practice change for net blotch management.

    Fungicide resistance management techniques explained in videos

    Three new GRDC videos have been produced to help growers understand how fungicide resistance develops and how they can prevent it from becoming an issue in their cropping programs.

    Co-innovation to curb barley blotches

    A unique approach has been taken to learn about the incidence of net blotch fungicide resistance across southern WA and researchers are now advocating the same approach is necessary for management

    Net blotch fungicide resistance profiling enriches knowledge base

    Field profiling research has shown resistance and reduced sensitivity in net blotch to demethylation inhibitor fungicides is widespread across the low-medium rainfall zone, whilst for succinate dehydrogenase inhibitors it appears to be regionally isolated. Initial feedback to Curtin University’s Centre for Crop and Disease Management, whose researchers undertook the work, has indicated that growers are implementing changes in field management, including crop rotations and improved stubble reduction in response to this information.

    Wet weather increases rust potential in 2022

    The wet summer and autumn period has provided favourable conditions for rust survival in the lead-up to the 2022 season in eastern Australia. The Plant Breeding Institute has already received early reports of stripe rust in wheat at Temora, Canowindra and Wallendbeen in New South Wales.

    High-residue systems may increase crown rot risk

    Plant pathologists encourage planning, particularly by those with stripper fronts, to mitigate the risk of crop losses to the disease Fusarium crown rot

    Fungicide timing essential for chocolate spot

    Recent crop disease surveys found that chocolate spot was all too common in faba bean crops in South Australia and Victoria. Field trials have demonstrated the yield benefit of selecting more resistant varieties and optimising fungicide application timing.

    Bacteria versus fungus – fighting Ascochyta carryover on stubble

    A new approach to managing Ascochyta blight in chickpeas aims to reduce the disease build up outside of the cropping season. As part of this approach, researchers at CSIRO are evaluating microbial inoculants with the ability to control Ascochyta rabiei.

    New stripe rust variant warrants caution

    A new pathotype of stripe rust with increased virulence on barley was detected in 2021. The new pathotype is not expected to cause damage in barley crops in 2022, but it will be critical to monitor the new variant.
