Other pests and diseases

Aside from phylloxera, a number of other exotic pests and diseases also present potential threats to viticulture in Victoria. Grape growers need to ensure their biosecurity practices (including farm hygiene and movement controls) minimise the chances of either phylloxera or other pests becoming established.


Exotic pests of grapevines

Whilst phylloxera has been the major biosecurity issue for Victorian grape growers, many pests not yet recorded in Australia are potential threats to our viticulture industries.

Exotic pests that are high priorities for Victorian viticulture include:

  • Angular leaf scorch (Pseudopezicula tetraspora)
  • Bacterial blight (Exanthomonas ampelina)
  • Black rot (Guignardia bidwellii)
  • Flavescence doree (Flavescence doree phytoplasma)
  • Glassy-winged sharpshooter (Homalodisca coagulata)
  • Grape mealybug (Pseudococcus maritimus)
  • Omnivorous leaf roller (Platynota stultana)
  • Pierce’s disease (Xylella fastidiosa)
  • Rotbrenner (Pseudopezicula tracheiphila)
  • Vine mealybug (Planococcus ficus)

For information on these pests, go to the Plant Health Australia Pest Information Document Database and select wine grapes, table grapes or dried fruit.

Vines should be checked regularly and any unusual or unknown pest or disease symptoms reported to the Exotic Plant Pest Hotline 1800 084 881.
