Phylloxera - the invisible hitch-hiker
South Australia has the oldest commercial grapevines in the world. That is because we have never had phylloxera (fil-ox-era) – an insect that attacks and kills grapevines.
By far the biggest risk for spreading phylloxera is humans. Phylloxera can be carried in soil, grapes, leaves or anything that picks up any of these. People can carry the insect on their footwear, clothing or vehicles.
Don't spread phylloxera!
Phylloxera can be present in a vineyard for several years before any symptoms are seen. This is why it is very important not to walk or drive in any vineyards without permission – especially if you have previously been in or near another vineyard interstate. You could accidentally pick up a phylloxera insect from one vineyard and transfer it to another one.
