摘　　要：通过8种杀菌剂的室内毒力测定，筛选出25％敌力脱EC对番茄早疫病菌抑菌力最强，EC50和EC95分别为0．0917μg／ml和1．47931μg／ml。田间防效试验结果表明,25％敌力脱EC2000～3000倍液能有效防治保护地番茄早疫病，番茄花期喷施2次25％敌力脱EC3000倍液、防效可达96．44％。The results from test of inhibiting Alternarni solani hyphae growth with 8 kinds offungicides indicated that the inhibting ability of 25% Propiconazole EC was the strongest. EC50 and EC95were 0.0917 ug/ml and 1. 4793 ug/ml. Field experiments showed that 25% Propiconazofe EC 2 000× ～3 000× dilution was able to control tomato early blight effectively in protective ground. The control effectreached to 96. 44% spraying with 25% Propiconazole EC 3 000× dilution twice in blooming Period oftomato.
