通过组织分离法，从温室大棚内发生南瓜苗期腐烂病的植株中分离得到一株菌株。采用南瓜茎人工接种试验进行致病性测定，确认该菌株为病原菌。经形态学鉴定，初步将该病原菌鉴定为瓜枝孢霉（ Cladosporium cucumerinum），编号为Cc-1。孢子萌发试验及温室防病试验结果表明：62.25％腈菌唑·福美双可湿性粉剂800倍液与75％百菌清可湿性粉剂600倍液对真菌Cc-1的孢子萌发抑制率均高于90％，温室防治效果分别为76.11％与75.50％。

A strain was isolated from pumpkin seedlings with rot disease in greenhouse by tissue isola -tion.The strain was determined as pathogen by artificial inoculation and pathogenicity test on pumpkin stem . The pathogen was preliminarily identified as Cladosporium cucumerinum by morphological identification , named Cc-1.The results of spore germination and control test in greenhouse showed that the inhibition rate of 800 times diluent liquid of 62 .25%myclobutanil and thirm WP and 600 times diluent liquid of 75%chlo-rothalonil WP on fungus Cc -1 spore germination were both over 90%, and the control effect in greenhouse was 76 .11%and 75 .50%respectively .
