摘要: 采用菌丝生长速率法,测定了采集自河南省北部和中部地区的2株禾谷镰刀菌对6种杀菌剂的敏感性。结果表明,菌株18HX2-1和菌株17LH01对氰烯菌酯、戊唑醇、多菌灵、己唑醇、丙环唑和三唑酮的敏感性均有差异,菌株18HX2-1对氰烯菌酯、戊唑醇和多菌灵的敏感性高于菌株17LH01,菌株17LH01对己唑醇、丙环唑和三唑酮的敏感性高于菌株18HX2-1。氰烯菌酯、戊唑醇和多菌灵对2株菌株的EC50均小于1 mg/L,抑菌效果较好,可用于小麦赤霉病的防治。

Abstract: Using mycelium growth rate method, the sensitivity of two strains of Fusarium graminearum which isolate from north and central of Henan province was identified to the 6 fungicides. The results showed that the sensitivity of strains 18HX2-1 and 17LH01 to phenamacril, tebuconazole, carbendazim, hexaconzole, propiconazole, triadimefon were different, strain 18HX2-1 was higher sensitive to phenamacril, tebuconazole, carbendazim than strain 17LH01, and strain 17LH01 was higher sensitive to hexaconzole, propiconazole, triadimefon than strain 18HX2-1. The EC50 of phenamacril, tebuconazole and carbendazim to two stains were less than 1 mg/L, which had better antimicrobial effect against two strains, and could be applied to control wheat scab.

Key words: wheat scab, Fusarium graminearum, fungicides, antimicrobial effect, sensitivity determination
