中文摘要: |
为了能筛选到对猕猴桃果梗干枯病菌(Glomerella septospora)具有高效抑制作用的杀菌剂,本文采用菌丝生长速率法测定了8种杀菌剂对该病菌的室内毒力,其毒力大小根据EC50值和毒力方程的斜率进行评判,结果表明肟菌?戊唑醇(WG)、戊唑醇(SC)、吡唑醚菌酯(EC)和氟硅唑(EC)4种药剂具有强烈的抑菌作用。以上4种杀菌剂可作为猕猴桃果梗干枯病田间药效试验的首选药剂。 |
英文摘要: |
In order to screen fungicides of high inhibition effect to Glomerella septospora, toxicity of eight fungicides to the fungus was tested by the mycelium growth rate method and was evaluated according to both the EC50 value and slope of toxicity regression equation. The results showed Trifloxystrobin?Tebuconazole (WG), Tebuconazole, Pyraclostrobin (EC) and Flusilazole (EC) had higher inhibition effect to the pathogen. These four fungicides are our first choice in field trial for controlling fruit stem blight disease of kiwifruit. |
