Anthracnose of cucurbits is widely distributed over the world wherever cucurbits are grown. Prothioconazole, is labeled for use in cucurbits but not specifically recommended for management of anthracnose; however, control of anthracnose ABSTRACT The causal organism responsible for the recent outbreak of almond and peach anthracnose in California was identified and characterized as Colletotrichum acutatum. The presence of well-defined and depressed circular leaf spots, dark in their core and surrounded by a light brown dim halo, was observed on Dendrobium nobile plants in the municipality of Ixtaczoquitlán, state of Veracruz, Mexico, in 2019. The disease produces at first water-soaked spots in leaves and then the lesions become brown and oval to spindle-shape or irregular and surrounded with yellow halos. The organism survives in alternate hosts, on volunteer black gram plants and on infected plant debris. There are no resistant varieties.
