The Tasmanian potato industry has been dealt another blow as the Potato Virus Y tuber necrosis strain (PVYNTN) has been found on multiple properties across the state.
The virus can cause significant damage to potato yields, reducing them by up to 80%.
Although the virus does not pose a danger to humans, it is known to cause ‘unsightly rings’ on the vegetable, making affected tubers unfit for consumption.
Primary Industries and Water Minister Jo Palmer said the Government was working closely with affected producers after the virus was detected on properties at Little Swanport, Bangor/Dunalley, Cressy and Connellys Marsh.
“Biosecurity Tasmania is working with the potato growers and a seed supplier to test and trace crops. The leaves of the affected crops have now been ‘burnt off’ which will reduce the chance of further spread of the disease,” Minister Palmer said.
“Advice and diagnostic support will continue to be offered to growers as they carefully dispose of symptomatic tubers and manage potato regrowth at the affected sites.
Biosecurity Tasmania is also working with potato growers and a seed supplier to test and trace crops, while also burning off the leaves of affected crops to reduce the likelihood of further spread.
PVYNTN was first discovered in Tasmania in 2021 when a small crop of Kipfler potatoes were infected in Cressy.
