荸荠[Eleocharis dulcis(Burm.f.)Trin.(异名:E.tuberosa Schult)],又称“马蹄”,属莎草科,是我国特有的水生淀粉作物。仅江苏栽培面积即在万亩以上。荸荠秆枯病俗称“荸荠瘟”、“细荸荠”,是一种真菌性病害,病菌为Cylindrosporium eleocharidisLentz。1982-1985年我们在江苏和浙江的主要荸荠栽培地区调查,发现荸荠秆枯病都有发生,且蔓延较快,造成荠秆大量死亡,影响产量。江苏荸荠秆枯病不仅为害茎秆,而且也为害叶鞘和花器,这与Lentz1962年报道的不同。
Eleocharis dulcis (Burm.f.) Trin. (Synonym: E. tuberosa Schult), also known as “horseshoe”, is a family of sedge, which is a unique aquatic starch plant in China. Only in Jiangsu cultivation area that mu mu. Water chestnut stem blight commonly known as “water chestnut blast”, “water chestnut”, is a fungal disease, bacteria Cylindrosporium eleocharidisLentz. From 1982 to 1985, we surveyed the major water chestnut cultivation areas in Jiangsu and Zhejiang Provinces and found that both water chestnut blight occurred and spread rapidly, causing a large number of water chestnut straw deaths and affecting the yield. Jiangsu water chestnut stem blight not only damage the stalks, but also damage leaf sheaths and flowers, which is not the same as Lentz1962 report.
