SA Plant Quarantine Standard

New Phylloxera related conditions in SA PQS

The Vinehealth Australia-led comprehensive review of the phylloxera-related conditions in South Australia’s Plant Quarantine Standard (PQS) has reached an important milestone, with The Minister for Primary Industries and Regional Development, the Hon. Tim Whetstone, recently approving a suite of changes.

These changes have been incorporated into a consolidated Condition 7 in the South Australian PQS Version 17 which you can access here.

Vinehealth Australia would like to acknowledge the considerable time and effort contributed to this review by PIRSA-Biosecurity SA and industry.

Please ensure you understand these changes, assess the impacts on your business, communicate relevant changes to your supply chain and implement practice changes to ensure you comply from 21 July 2020 onward.

Review of the new Condition 7 will be ongoing to maintain alignment with new science and contemporary biosecurity knowledge.

Key changes incorporated into the new Condition 7 in Version 17 of South Australia’s PQS 

  • Steam as a sterilisation treatment method for all machinery or equipment being imported into SA is now prohibited;
  • The entry of used netting, trellis posts, vine guards, dripper tube, wire and clips into SA is now prohibited;
  • The entry of winegrapes grown in a Phylloxera Risk Zone (PRZ) into SA is now prohibited;
  • Alignment of entry requirements for equipment from a PRZ with tougher standards applicable for equipment from a Phylloxera Infested Zone (PIZ) and Phylloxera Interim Buffer Zone (PIBZ);
  • Alignment of entry requirements for grape marc, with that of winegrapes.

We have outlined the key changes incorporated into Version 17 of South Australia’s PQS and what they mean to you as stakeholders, in a flyer here which has been sent to all registered Vineyard Owners on our Vineyard Register. 

Areas requiring further consideration

The review has highlighted three areas that require additional discussion with PIRSA-Biosecurity SA, interstate counterparts and industry, being:

  1. Current entry of grape harvesters from a PRZ, PIZ, PIBZ into South Australia.
  2. Current entry of must or unfiltered juice from a PIZ or PRZ into South Australia for winemaking under ICA-22.
  3. Current lack of certification for filtered juice entering South Australia, sourced from grapes grown in a PRZ, PIZ or PIBZ.

Vinehealth continues to actively progress these matters but did not want resolution of these to hold up endorsement of the suite of other changes ready for approval by the Minister.

Your role

Protection of South Australia’s wine industry from phylloxera and other significant pests and diseases can only be achieved through the collective efforts of industry and government.

Please ensure you always maintain focus on compliance with South Australia’s updated PQS to avoid inadvertently introducing and spreading phylloxera. We also ask you to strongly encourage your neighbours, suppliers and community to follow the rules. We urge you to also continue your focus on implementing strong farm-gate hygiene practices to the collective benefit of the South Australian wine industry.

The PQS review process

The intent of the review was to protect South Australia’s $2.15 billion wine industry. We have some of the oldest vines in the world in SA and we are collectively custodians of our viticultural assets. Our industry now operates in a heightened biosecurity landscape and is more interconnected than ever before.

The review of the phylloxera-related conditions in South Australia’s PQS was undertaken using a risk-based approach to strengthen the conditions under which items that can pick up and spread phylloxera, may enter the State. The work involved completed of a state pest risk analysis for grape phylloxera and an evaluation of recent phylloxera research around efficacy of disinfestation protocols.

There are significant movements of grapes, grape products, machinery, equipment and people between countries, states, regions and individual properties. Phylloxera is on the move in the Yarra Valley, Victoria, and the risk of pick up and spread of this pest into SA has never been higher. An overarching review of the grape phylloxera conditions in South Australia’s PQS had not been undertake since 2009, when the National Phylloxera Management Protocol was published.

As part of this review, Vinehealth Australia undertook an extensive industry consultation stage over a 12-month period. We created and distributed a Consultation Pack to more than 3,300 stakeholders seeking feedback. We discussed proposed changes to the PQS with more than 150 stakeholders across 39 meetings, covering 10 viticultural regions or zones in South Australia.
