The wine louse (phylloxera vastatrix) has been found in Australia. The dreaded insect showed it’s ugly head in Europe at the end of the 19th and early 20th centuries and almost wiped out all of Europe’s vineyards. Luckly, someone found the remedy: graft the European vines on American rootstocks to get a disease resistant plant. Three years ago the devastating insect was found in a small area in Australia but seemed to have been fought back.
Now it has been found again, this time in the Yarra Valley. The risk for the winegrowers is that they will have to do expensive replantings if the pest spreads. No end to the misery in Australia it seems.
