What is Pierce's Disease?

Pierce's Disease is a bacterial infection, which is spread by bugs that feed on grapevines, particularly the "glassy winged sharpshooter." Grapevines that become infected with PD can quickly become sick and die.

New Australian record for Xiphinema vuittenezi on Vitis vinifera

  • Author(s): Walker, Gregory;
  • Abstract: Xiphinema vuittenezi is reported for the first time in Australia in soil associated with roots of declining grapevines (Vitis vinifera) in a Barossa Valley (SA) vineyard. This nematode may be able to transmit some strains of Cherry leaf roll virus and is the putative vector of Grapevine chrome mosaic virus; hence its finding may have potential significance for the spread of some nepoviruses in grapes and other hosts.
