Exobasidium leaf and fruit spot, caused by the fungus Exobasidium maculosum, is an emerging disease affecting both southern highbush and rabbiteye blueberries. In addition to direct yield loss due to fruit drop, lesions on remaining fruit compromise the aesthetic qualities of the fruit as well as the taste, rendering them unmarketable. This circular provides the most current knowledge of this important pathogen/disease of blueberry and its management.
