| Abstract: | In June 1996, a leaf spot disease widely occurred in Japanese persimmon (Diospyros kaki) orchards in Tottori Prefecture, Japan. The main diagnostic symptom was ring spot on the leaves and calyxes of young fruits; in severe cases, lesions developed on more than half of the area of the leaf, resulting in early defoliation. Based on morphological and pathological studies of the isolated fungi, it was shown that Pestalotiopsis longiseta, P. glandicola, P. acaciae, and P. crassiuscula were responsible for the diseases. These fungi, except P. longiseta, were found to be new pathogens of the disease. Received: May 20, 2002 / Accepted: July 25, 2002 |
