摘　　要：从香石竹扦插茎腐苗上分离纯化了35株镰刀菌，优势菌为：串珠镰孢（F．moniliform Sheldon）11株，串珠镰孢中间变种（F．moniliforme var．intermedium Neish＆leggestt）9株，尖孢镰孢（Fusarium oxysporum Schlecht）8株，其次还有茄病镰孢蓝色变种（Fusarium solanivat．coeculeum（Sacc．）Booth）等7株，共6个种和变种；选用12株菌检测其致病性，其中11株菌的致病率高达88～100％；农药药效实验表明。大生的效果最好，0．1g／L即能完全抑制5株试验菌的生长；其次为甲霜灵-锰锌；根病必治的效果最差。35 Fusarium strains were isolated from rotted carnation stems by shoot tip culture. The dominant species were F. monili forme Sheldon （11 strains）, F. monili forme var. intermediurn Neish ＆ Leggett （9 strains） and Fusarium oxysporum Schlecht （8 strains）. The other 7 isolated strains were identified as Fusarium solani var. coeculeum （Sacc.） Booth and other species, There were 6 species and varieties isolated from the stems, The pathogenicity of 12 strains was detected, and pathogenetic rates of 11 strains were 88~ 100~. The test results of some fungicides destroyed 5 strains of pathogenic fungi research showed that Dithane M-45 and Metalaxyl-mancozeb restrained growth of those pathomycetes thoroughly.
