Sclerotinia rot of blueberry caused by Sclerotinia sclerotiorum


In 2002, rotted flower clusters and blighted shoot tips and leaves were observed on highbush blueberry (Vaccinium corymbosum L.) and rabbiteye blueberry (V. ashei Reade) plants in Chiba, Japan. The causal fungus isolated from the diseased plants was morphologically identified as Sclerotinia sclerotiorum (Libert) de Bary. The fungus reproduced natural symptoms after inoculation, then reisolated from the symptomatic parts. This is the first report of blueberry sclerotinia rot caused by S. sclerotiorum.
