荸荠秆枯病Cylindrosporium eleocharidis Lentz是荸荠上的一种重要病害。但对此病及其病原菌的研究甚少,尤其是此病病原菌在人工培养时,不易产生大量的分生孢子,给病害的深入研究带来了困难。为此,作者对此病原菌的产孢及孢子萌发条件进行了研究,并对杀菌剂作了初步筛选。主要结果如下: Water chestnut bacterial blight Cylindrosporium eleocharidis Lentz is an important disease on water chestnuts. However, little research has been done on the disease and its pathogens, especially when the pathogen of the disease is not easy to produce a large number of conidia during artificial cultivation, which makes it difficult for the further study of the disease. To this end, the author of the pathogen spores and spore germination conditions were studied, and the initial screening of fungicides. The main results are as follows:
