This week we advised industry via a Biosecurity Alert that Agriculture Victoria has confirmed the detection of phylloxera in a vineyard inside the current Maroondah Phylloxera Infested Zone (PIZ) in the Yarra Valley.

Given the location of the vineyard in the southeastern corner of the Maroondah PIZ, this detection will result in an extension to the current boundary of the Maroondah PIZ (refer Agriculture Victoria’s map).

Genotyping of the detected phylloxera has confirmed the strain as G1; the same strain already known to exist in the Maroondah PIZ. 

The process of formally gazetting the new Maroondah PIZ boundary is now underway by Agriculture Victoria. In the interim, and according to PIRSA’s Deputy Chief Inspector Biosecurity Notice, the 5km quarantine zone is considered a Phylloxera Interim Buffer Zone (PIBZ) under South Australian legislation.

It is important to note that the conditions of entry into South Australia for regulated items from a PIBZ are the same as that from a PIZ. Refer to Condition 7 in the SA Plant Quarantine Standard.
