During 1984 to 1986, 240 wilted samples of water chestnuts [Eleocharidis dulcis (Burm. f.) Trin. ex Henseflower] were collected from eleven counties and cities in Zhejiang Province, four species of Fusarium were isolated: i. e. Fusarium oxysporum, F. acuminatum, F. semitectum, F. moniliforme var. intermedium. Field observations and artificial inoculations showed that water chestnut wilt was caused principally by F. oxysporum, this is a new disease on water chestnut and has not been hitherto reported. The symptoms of the disease are stunting, yellowing, basal rot and in the later stage, wilting of the stems, inoculation tests on a number of species of truck crops showed F. oxysporum to be highly specific to E. dulcis.
