| 摘 要： | 为筛选出防治芝麻立枯病的高效杀菌剂,采用菌丝生长速率法测定10种杀菌剂对芝麻立枯病菌的抑制作用。室内毒力测定结果表明:氟硅唑对芝麻立枯病菌的抑制效果最好,EC50值最小,仅为0.5751 mg/L,其次为吡唑醚菌酯,EC50值为0.9199 mg/L。啶酰菌胺和多菌灵对立枯病菌也有较强的抑菌效果,EC50值分别为1.3770 mg/L和1.5138 mg/L。氟硅唑和吡唑醚菌酯抑菌效果显著,可作为芝麻立枯病的首选药剂。

| Abstract: | This study is to select effective fungicides to control sesame damping-off. The inhibition effect of ten fungicides against Rhizoctonia solani was determined by the mycelial growth rate test. The results indicated in laboratory that flusilazole showed the best inhibitory activity with the lowest EC50 （0.5751 mg/L）, followed by Pyraclostrobin with EC50 value （0.9199 mg/L）. Boscalid and carbendazim also have better effective, which values were 1.3770 mg/L and 1.5138 mg/L respectively. Flusilazole and pyraclostrobin had strong inhibition effect, could be used to control sesame damping-off. |
