Black Leaf Spot Phase of Strawberry Anthracnose Caused by Colletotrichum gloeosporioides (=C. fragariae). C. M. Howard, Professor of Plant Pathology, University of Florida, Agricultural Research Center, Dover 33527. E. E. Albregts, Professor of Soil Science, University of Florida, Agricultural Research Center, Dover 33527. Plant Dis. 67:1144-1146. Accepted for publication 26 April 1983. Copyright 1983 American Phytopathological Society. DOI: 10.1094/PD-67-1144.

Since the mid-1970s, a new leaf spot of strawberries has been found in summer nurseries in Florida. Isolations from the lesions consistently yielded a Colletotrichum sp. identical to the original description of C. fragariae. In inoculation tests, an isolate from a leaf lesion and an isolate from the crown of a wilted plant incited leaf spot and typical anthracnose symptoms on stolons and petioles.
