Biosecurity New Zealand is working with Potatoes New Zealand to respond to a detection of Potato mop-top virus (PMTV) in potato tubers in Canterbury.
Incident controller, David Yard, emphasizes Potato mop-top virus is not a food safety issue.
David Yard, incident controller:
“Potato mop-top virus is a crop disease which, if found to be wide-spread, could cause some productivity issues for growers.”
“It is a notifiable and unwanted organism in New Zealand under the Biosecurity Act.”
Mr Yard says to date, potato tubers from two properties in the Canterbury region have tested positive for the virus. Further sampling is under way in the region.
David Yard:
“This is the first time the virus has been found in New Zealand, however it is common in other countries.”
Chris Claridge, Potatoes New Zealand chief executive:
“The industry is working closely with Biosecurity New Zealand to learn more about the virus, the impact it could have on growers, and to stop any risk of spread.”
“We will then consider if it is possible to eradicate it, or whether we will need to work with growers to manage its impact over the long term.”
The Innovator variety of potato was last imported as germplasm into New Zealand in July 2011.
Innovator is a russet type potato with shallow eyes and cream coloured flesh. High resistance to cyst nematodes, wart disease, leaf and tuber blight. Innovator is an excellent variety for boiling, baking and French frying. Innovator has a remarkably good flavour. The ability to recondition from long term storage makes this an ideal variety for processors.

Biosecurity New Zealand is investigating how the virus may have entered the country.
