Of the pests and diseases endemic to Australia, our greatest biosecurity threat is grape phylloxera. In Australia, grape phylloxera is currently confined to parts of Victoria and New South Wales.
Commercial vine plantings in Australia are predominantly own-rooted Vitis vinifera, highly susceptible to phylloxera. Preventing its movement to currently uninfested areas is therefore of utmost importance.
In this fact sheet, we discuss phylloxera’s lifecycle, feeding, strains and signs of infestation, as well as how it’s spread and where it’s located in Australia.
