摘　　要：近年贵州赤水市种植的金钗石斛(Dendrobium nobile Lindl)炭疽病(烟煤病)发生较多,该病害分布广、危害严重。对金钗石斛炭疽病菌的生物学特性、培养性状及形态等研究,初步确定病原菌为胶孢炭疽菌(Colletotrichum gloeosporioides),结合ITS序列分析,确定该致病菌为胶孢炭疽菌。杀菌剂室内抑菌试验结果表明多菌灵对其有较好的抑制作用。In recent years,the nobile anthrax are widely distributed in Chishui,Guizhou province.The diseases are extremely harmful on plant growth.All the pathogens were identified morphologically and ITS sequence data were used to identify the pathological strains.Antimicrobial fungicide,carbendazim is the best inhabitant agent against these pathogens.
