摘　　要：对银杏叶枯病病原菌进行分离鉴定,在发病初期的致病病原菌为半知菌亚门丝孢纲丝孢目链格孢菌(Alter-naria alternata(Fr.)Keissl)。分别用3种供试杀菌剂:25%敌力脱乳油,90%疫霜灵可湿性粉剂,50%扑海因可湿性粉剂及对照药剂40%百菌清可湿性粉剂对银杏叶枯病病原菌进行室内生物测定,结果表明:3种供试药剂对银杏叶枯病病原菌的抑菌效果均好于对照药剂,其中以25%敌力脱乳油抑菌效果最好。The identification of the pathogen of Gingko Blight shows that ： in the beginning of the disease, the pathogen is Alternaria alternate. With three antiseptics,25% propiconazole oil,90% fosetyl- aluminium water- able powder,50% iprodione water-able powder and 40% chloroehalonil water -able powder as CK. All the effects of the above three germicide are better than the 40% chloroehalonil water -able powder. The 25% propiconazole oil shows the best antiseptic effect.
