Black Leaf Spot Phase of Strawberry Anthracnose Caused byColletotrichum gloeosporioides(=C. fragariae)

Abstract

Since the mid-1970s, a new leaf spot of strawberries was found in summer nurseries in Florida [USA]. 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.
