Work is currently underway by Agriculture Victoria regarding the establishment of a PIZ in accordance with the National Phylloxera Management Protocol given this new detection.
“This latest phylloxera outbreak in Victoria is a concerning development,” said Vinehealth Australia CEO Inca Pearce. “It highlights the critical role that industry must play in preventing further spread. The outbreak is also clear evidence of the need for a new national management strategy for phylloxera, on which work has recently commenced. We need to do everything in our power to protect our vines and manage the risk.”
Australian Grape & Wine CE, Tony Battaglene goes on to say “Pests and diseases are a major risk to the Australian wine sector. Managing this risk should remain a high priority for all grape and wine producers and Australian Grape & Wine is committed to raising biosecurity awareness across the sector.”
What should industry do?
All operators have an obligation to actively undertake measures to prevent the movement of pests, diseases and weeds, including phylloxera, as part of their shared responsibility for biosecurity.
Contact your state regulator to discuss any queries you have regarding the movement of these phylloxera vectors.
NOTE: If you are moving any of the above items out of the 5km quarantine area at St Andrews, you MUST comply with movement conditions stated in Agriculture Victoria’s Industry Notice.
Agriculture Victoria and Wine Yarra Valley are working together to assess and manage the impact of the detection and implications for the existing Maroondah PIZ boundary.
Vinehealth Australia and Australian Grape & Wine will continue to monitor the situation and work together to communicate information to industry regarding this detection and to ensure that insights gained can be used to prevent the further spread of phylloxera.
From a regulatory perspective in SA, Vinehealth Australia is working closely with Biosecurity SA to evaluate and monitor the risk this detection poses and to ensure strong state Plant Quarantine Standards.
About phylloxera in Australia
Phylloxera is a devastating soft bodied insect pest of grapevines worldwide, affecting Vitis species (commercial grapevines and ornamental vines). There are 83 endemic strains in Australia that are confined to a number of wine regions in parts of Victoria and New South Wales. It represents a major threat to the vast majority of Australia’s vineyards that are planted on own roots, which are highly susceptible to attack by the pest.
Australian grapegrowing regions are delineated by phylloxera status into three management zones:
