Xylella symposium presentations, report and economic impact study now available

November 27, 2017

The report and speaker presentations from the International Symposium on Xylella fastidiosa, held in Brisbane on 17-18 May 2017, are now available on the Department of Agriculture and Water Resources website. Xylella is the number 1 pest of the National Plant Pest Priorities that are exotic to Australia, under eradication or have limited distribution due to wide host range and impact.

The symposium covered four themes with 17 presentations on:

  • Xylella and its vectors
  • Diagnostics and surveillance
  • Management and control
  • Research and collaboration.

The report provides key scientific information underpinning Xylella preparedness activities, its subspecies and genetic strains, and the management of the pathogen and its insect vectors overseas. It will be used to provide information and guide future investments in preparedness for this important exotic disease.

The ABARES report on the ‘Economic impacts of Xylella fastidiosa on the Australian wine grape and wine-making industries’ – presented by Dr Tony Arthur at the symposium – has also been released.

According to the report, a Xylella fastidiosa incursion could cost Australia’s wine grape and wine-making industries up to $7.9 billion over 50 years.

Although focused on the potential costs to the Australian wine industry, the modelling framework could be adapted to other perennial crops susceptible to Xylella, including horticultural crops (such as cherries, citrus, nuts, olives and summer fruit), native trees, amenity trees, forests and grasses.
