First Report of Anthracnose Caused by Colletotrichum nymphaeae on Strawberry Fruits in Korea

Anthracnose fruit rot (AFR) has been observed in greenhouses during the harvesting periodin the Chungnam Province of South Korea. Fruits infected inside the greenhouse show blackor brown spots, orange conidial masses and in some areas of the infected parts, white fungalgrowths are visible. The size of these spots gradually expands, leading to the necrosis of thefruits and flowers. Three isolates were obtained from infected fruits and identified as strainsof the Colletotrichum acutatum species complex based on morphological characteristics. Multilocus sequence analysis of actin, chitin synthase, glyceraldehyde-3-phosphatedehydrogenase genes, and internal transcribed spacer rDNA regions revealed that theisolates belong to a monophyletic group with the type strain of C. nymphaeae. This is thefirst time C. nymphaeae has been confirmed in strawberry fruit in Korea. KCI Citation Count: 0
