In 2006, crown rot of strawberry (Fragaria x ananassa Duchesne cv. Kentaro) was observed in production field in Hokkaido, Japan. The causal agent was identified as Colletotrichum acutatum Simmonds ex Simmonds, based on morphological characteristics, sensitivity to the fungicides benomyl and diethofencarb, and results of a polymerase chain reaction (PCR) using a specific primer. Inoculation tests with C. acutatum revealed that the fungus caused the same symptoms on strawberry plants and was re-isolated from the symptoms. This is the first report of anthracnose crown rot on strawberry caused by C. acutatum in Japan.
