OCCURRENCE OF ANTHRACNOSE FRUIT ROT CAUSED BY COLLETOTRICHUM ACUTATUM ON DAY-NEUTRAL STRAWBERRIES IN MANITOBA

摘要

Anthracnose fruit rot of strawberry, caused by Colletotrichum acutatum, was observed in August, 1994 in a strawberry cultivar yield trial at Morden, Manitoba. The disease was found on five day-neutral cultivars. Incidence of fruit rot ranged from 11% on cv. Seascape to 82% on Fern. The pathogen may have been introduced via transplants imported from California as this disease has not been previously detected in commercial strawberry fields in Manitoba. This is the first official report of C. acutatum on strawberry in Canada.
