The viticulture industries (wine and tablegrapes) – through the National Vine Health Steering Committee – developed a National Phylloxera Management Protocol, which is an agreed standard for managing the movement of risk vectors so as to minimise the risk of spreading phylloxera.
The national protocol covers the movement of grapevines, vineyard machinery, grapes, people and grape products from Phylloxera Infested Zones and Phylloxera Risk Zones into non-infested zones (see map of phylloxera zones in Australia). It gives details on the recommended disinfestation treatments for machinery, footwear, vehicles etc that can be applied in any vineyard situation.
Note that the NPMP was published in 2009 and phylloxera research undertaken since, has found some of the disinfestation procedures within this document ineffective against Australia’s key endemic phylloxera strains. For example:
- Footwear and small hand tool disinfestation is ineffective in a 2% sodium hypochlorite solution at 30 seconds with a water rinse thereafter. This has been replaced since January 2017 with a 2% sodium hypochlorite solution for 60 seconds without a water rinse thereafter. An alternative available from September 2021 is to use undiluted Dettol for 60 seconds without a water rinse thereafter.
- Machinery and equipment sterilisation is ineffective when conducted for a duration of 2 hours at 40 degrees Celsius. This has been replaced in South Australia’s Plant Quarantine Standard since May 2020 for a duration of 3 hours when undertaken at 40 degrees Celsius.
