Potato mop-top virus detected in Tasmania

AUSVEG and Biosecurity Tasmania are alerting growers and industry stakeholders to the detection of Potato mop-top virus (PMTV) in Northwest Tasmania. This marks the first time this virus has been found in Australia.

Biosecurity Tasmania is actively managing the situation with an Incident Management Team (IMT). They are conducting surveillance, diagnostics, and tracing operations to determine the extent of the virus's spread and its source. Control measures have been put in place to manage the movement of potentially infected potatoes and soil.

What you need to know

  • No Food Safety Risk: PMTV and powdery scab (Spongospora subterranea) do not pose any food safety or human health risks. Potatoes remain safe to eat.

  • How it Spreads: PMTV is a plant virus that primarily impacts potato quality and development. It is most commonly spread by the soil-borne pathogen that causes powdery scab.

What Can You Do?

  • Implement and maintain good biosecurity practices on your property, including a dedicated high-pressure wash station for gear, clothing, machinery and equipment.

  • Limit the movement of contractor vehicles within production areas and paddocks whenever possible.
