Occurrence of Pseudoperonospora cubensis pathotype 5 on squash in Italy
Plant Disease 87 (4), 449-449
Abstract: During 2002, squash (Cucurbita pepo) plants grown in Italy were observed with symptoms of downy mildew, including yellow spots on the upper leaf surface. The fungus Pseudoperonospora cubensis was isolated from the diseased plants. The identification was based on morphological characteristics. Pathogenicity of the isolates was demonstrated by inoculation and re-isolation. Inoculations tests with four fungal isolates and different species of cucurbits suggested that the fungal isolates from squash are pathotype 5.
