Phylloxera Management Zones in Australia

In February 2020, Agriculture Victoria confirmed new phylloxera detections in the Yarra Valley – both inside the current Maroondah Phylloxera Infested Zone (PIZ) and outside the PIZ in the Phylloxera Risk Zone (PRZ) to the south-east of the Maroondah PIZ, near Yarra Junction. On 9 July 2020 the expanded Maroondah PIZ boundary was gazetted to include the areas of Woori Yallock, Launching Place, Yarra Junction, Wesburn, Hoddles Creek, Beenak, Gladysdale and Three Bridges.
