Chestnut Blight

Australia’s first outbreak of Chestnut Blight was recently confirmed, following detections of the disease at nine properties in the Ovens Valley in north-eastern Victoria.

Biosecurity SA has undertaken surveillance for Chestnut Blight at several commercial chestnut orchards in the Adelaide Hills and there have been no detections of the disease in South Australia.
South Australia’s chestnut industry is small, with several commercial and non-commercial growers located in the Adelaide Hills. There are about 350 chestnut growers nationally, with the majority of producers in north-east Victoria.

Biosecurity SA is working closely with local industry representatives to encourage growers, hobby farmers and home gardeners to check their trees.

To report suspect cases of Chestnut Blight, please contact Biosecurity SA’s Exotic Plant Pest Hotline on 1800 084 881.

What is Chestnut Blight?

A declared exotic disease, Chestnut Blight (Cryphonectria parasitica) can kill individual branches and entire trees, infecting chestnut, oak, red maple and eucalyptus.

The disease typically occurs in Japan, China, Korea, the United States of America, Canada, and Europe.

Chestnut Blight is a bark-inhibiting fungus and causes cankers that can girdle the stem or branches.
Under favourable conditions orange fruiting bodies are produced on the outside of the bark, inside the canker.

Example of Chestnut Blight
