摘要
对采集于贵州省水城县、清镇市等地竹荪种植基地的腐烂竹荪球进行病原菌分离、培养、鉴定,分离到4种致病真菌:茄病镰刀菌[Fusarium Solani(M art.)Sacc.]、绿色木霉(Trichoderma viridePers.)、匍枝根霉(Rhizopus stoloniferL ind)、拟青霉(Paecilomyces variotiBain.)。用70%甲基托布津、50%多菌灵、施宝功、抑唑霉、70%敌克松等5种杀菌剂对以上4种病菌进行室内抑菌试验,施宝功500倍液对以上4种病菌的抑制率分别为71.3%,67.4%,58.7%和73.2%,甲基托布津500倍液对以上4种病菌的抑制率分别为68.4%,64.5%,60.7%,63.6%。多菌灵、抑唑霉、敌克松的防治效果不明显。
Four pathogens were isolated from the rotten fruit bodies of Dictyophra rubrovolvata collected from Shuicheng and Qingzhen of Guizhou province. They were cultured and identified as Fusarium solani （ Mart. ） Sacc, Trichoderma viride, Rhizopus stolonifer and Paecilomyces varioti. Five fungicides were tested in vitro for the efficacy against these pathogens in the laboratory. The inhibitive rate of Shibaogong and Thiophanate-methyl for them was 71.3%, 67.4%, 58.7% and 73.2%, and 68.4%, 64.4%, 60.7% and 63.6%, respectively. The inhibition effects of Carbendazim, Yizuomei and Fenaminosulf were not satisfactory.
