クラドスポリウム属菌によるブドウの褐点病について

Cladosporium cladosporioides (Fresenius) de Vries and Cladosporium herbarum (Pers. ) Link ex Fr. were isolated from grape berries that had been commonly called 'black navel', and were found to cause the disease. In view of the colour of lesions that were observed most frequently at the stage of maturing, the disease was named brown spot of grapes.
