Abstract
Anthracnose of netted melon (Cucumis melo var. reticulatus Naud.) which appeared on leaves, petioles, stems and fruits was observed in Miyagi prefecture in 1997. The causal fungus was isolated from the netted melon and identified as Colletotrichum orbiculare (Berkeley & Montagne) Arx, based on its morphology, growth temperatures, and pathogenicity. Inoculation experiments revealed that 17 species plants belonging 10 genera of Cucurbitaceae and six species of plants belonging to six genera in three other families were infected by the pathogen. This is the first report of anthracnose of netted melon caused by Colletotrichum orbiculare in Japan.
