Bleeding canker of horse chestnut


Bleeding Canker of Horse Chestnut is a common canker of horse chestnut trees (Aesculus hippocastanum, also known as conker trees) that is known to be caused by infection with several different pathogens.
Infections by the gram-negative fluorescent bacterium Pseudomonas syringae pathovar aesculi are a new phenomenon, and have caused most of the bleeding cankers on horse chestnut that are now frequently seen in Britain.
