Since 2001, root rot of grafted cucumber (Cucumis sativus L) caused by Phomopsis sp. has been observed in open-field cultivation in Fukushima, Japan. Symptoms, such as wilting of the plants, were first observed in early August. A difference in susceptibility was observed among rootstock varieties (Cucurbita spp.) when seedlings were grown in infested soil. To our knowledge, this is the first report on the occurrence of root rot in open-field-cultivated cucumber in Fukushima.
