With the national management group overseeing the official biosecurity response to PMTV under the emergency plant pest response deed (EPPRD) coordinated by Plant Health Australia having determined the virus is not technically feasible to eradicate following its detection in Tasmania earlier this year, the national transition to management to industry is underway.
As the peak industry body for Australia’s potato industry, and the sole organisation representing potato growers that is a formal party to the EPPRD, AUSVEG update the current status of PMTV and affirmed the national approach as the transition to management progresses.
PMTV has only been confirmed as present in Tasmania, with restrictions and conditions remaining in place in Victoria, NSW, and South Australia on the movement of potatoes from the island state to the mainland.
AUSVEG’s strong position remains that a consistent, science and evidence-based approach to the safe movement of seed, ware and processing potatoes is needed nationally to facilitate continuation of trade where possible, while mitigating and managing risks.
That consistency has become increasingly important with Biosecurity Tasmania having now confirmed it is winding down its official response to PMTV, meaning the virus moves to be managed through the potato production process by industry.
To this end, AUSVEG also brought key government and potato industry stakeholders and decision-makers together in Melbourne in November to promote a consistent national approach to the ongoing management of mop-top virus.
During the November meeting, invitees including all state and federal biosecurity agencies, chief biosecurity officers, and industry and grower representatives discussed the safe, and risk-based movement of potatoes, including seed, across the country.
“The detection of potato mop-top virus in Tasmania earlier this year has presented significant challenges and considerations for potato growers, both in Tasmania and across the country,” AUSVEG chief executive Michael Coote says.
“As the national biosecurity focus moves to management of PMTV, AUSVEG is committed to promoting a biosecurity approach which enables business continuity, trade and market access for the seed, ware and processing potato industry through uniform testing, tracing and trade protocols, as part of our ongoing efforts to protect and progress the interests of Australian potato growers,” Michael says.
While PMTV can affect potato crop yield and quality, it is important to note there are no impacts on human health and potatoes remain safe to eat.
Testing undertaken on Tasmanian seed which arrived on the mainland before restrictions were put in place has only resulted in a positive detection in one seed line which remains unplanted and under a biosecurity order.
The detection has been verified by Agriculture Victoria.
This seed has remained in quarantine, as arrangements are made for safe destruction, in alignment with formal biosecurity protocols.
All other Tasmanian seed lines were imported onto the mainland have not detected the presence of PMTV.
If testing has not detected PMTV – and unless there is a specific biosecurity order on a seed lot or property – the decision to plant remains for individual businesses to make, noting advice from state regulators must be adhered to.
Deviating from this position risks undermining national biosecurity testing protocols, which our certification schemes, and export market access are also reliant on.
As the transition to management of the virus continues, AUSVEG, along with the Commonwealth and Plant Health Australia, is working through options for reimbursement and compensation for growers who have experienced financial losses or incurred costs because of jurisdictional biosecurity orders as part of the response to PMTV.
Legal details are also being worked through, and AUSVEG will communicate these as clarity is achieved.
