摘　　要：为了有效控制芒果蒂腐病对多菌灵的抗药性,采用生长速率法,对2株抗多菌灵的芒果蒂腐病菌菌株进行了21种杀菌剂的室内毒力测定,以期筛选出对抗多菌灵菌株毒力强的杀菌剂,为防治抗多菌灵的芒果蒂腐病提供理论依据。通过EC50值和EC90值综合分析,在供试的21杀菌剂中,对抗多菌灵的芒果蒂腐病菌菌株毒力强的杀菌剂是异菌脲、丙环唑、戊唑醇,其次为腈菌唑、咪酰胺锰盐、咪酰胺、氟硅唑、吡唑醚菌酯和苯醚甲环唑,这9种杀菌剂均可作为防治抗多菌灵的芒果蒂腐病的首选杀菌剂;另外,烯唑醇和百菌清的EC50值和EC90值均相对较低,也可作为防治抗多菌灵芒果蒂腐病的杀菌剂。To effectively control the resistance of mango stem end rot to carbendazim, the toxicity of 21 fungicides to earbendazim-resistant Botryodiplodia theobrornae Pat., pathogen of mango stem end rot were tested by myeelium growth rate methods in laboratory. The aim of this research was to select fungicides which are most toxic to carbendazim-resistant strains of Botryodiplodia theobromoe Pat. The test results were analyzed by the EC50 value and the EC50 value. The toxicity of iprodione, propiconazole and tebucomazole to earbendazim-resistant B. theobromae were prior to other tested fungicides, followed by myclobutanil, sporgon, prochloraz, flusilazole, pyraelostrobin and difenoconazole. These 9 fungieides were the first choices for control of mango stem end rot resistant to carbendazim. In addition, the EC50 values and the EC50 values of dinieonazole and chlorothalonil were lower than other fungicides. These two fungicides could be alternatives for control of mango stem end rot resistant to carbendazim.
