DISEASE

NAME
Coral Spot
Nectria cinnabarina

Description
A casual fungal problem that attacks broad-leafed shrubs and trees.



Symptoms
The fungus causes the twigs and branches to die back followed by rounded pustules that are pink to coral red producing spores. The branches become brittle and in extreme cases the plant dies.



Source and Dispersal
The fungus is derived from other infected plants and the spores are dispersed by wind. Infection occurs by entering the plant through wounds, normally the result of poor pruning techniques or wind damage.

Favoured Conditions
There are no current references to favoured conditions but generally fungal attack occurs during humid weather.
     
Affected Plants
A wide range of ornamental trees andshrubs are infected includingAcer,Cercis , Morus, Juglans,EleagnusandMagnolia species.

Non-chemical Control
Cut back and destroy infected branches and remove heavily affected plants. Use sharp tools when pruning, avoiding snagging the wood and use disinfectant on the blades between plants.

Chemical Control
There is no satisfactory chemical control.
Note
Always read the label for registration details and direction of use prior to application of any chemicals.
