Grapevine Virus Detected in Australia for the First Time

A grapevine virus known to affect plant growth and fruit quality has been detected in Australia for the first time.

The Grapevine Berry Inner Necrosis Virus has been identified in vineyards in South Australia, Victoria and Queensland.

Authorities say the virus has been found in both symptomatic and asymptomatic vines, with the full extent of its spread not yet known.

Some infected plants have shown reduced growth in spring, although symptoms can vary and vines may appear normal as the season progresses.

Overseas, the virus has been associated with impacts on table grape production, including smaller berries, slower ripening and reduced quality.

The disease spreads through infected planting material, grafting and by grapevine mites, and there is currently no known cure.

Experts believe the virus may have been present in Australia for some time, meaning eradication is not considered feasible.

Growers are instead being advised to focus on monitoring, hygiene and risk management, as the industry conducts further investigations into how the virus can be managed and its impact minimised.
