摘　　要：SiO2水溶胶制剂和百菌清可湿性粉剂对番茄叶霉病防治效果的研究结果表明,SiO2水溶胶和百菌清可湿性粉剂对番茄叶霉病均有明显的抑制作用。0.5,1.0,2.0,3.0 g/L的SiO2水溶胶和500倍75%的百菌清可湿性粉剂对番茄离体叶片叶霉病的防治效果在处理7 d后分别为43.34%、55.03%、60.46%、55.75%、58.18%;对室内盆栽番茄苗叶霉病的防治效果在处理15 d后分别为12.47%、17.79%、43.61%、24.61%、41.85%,以2 g/L的SiO2水溶胶防治效果最好。The effect of SiO2 hydrosol and preehit wettable powder on leaf mold of tomato was studied.The result showed that leaf mold of tomato was significantly inhibited by SiO2 hydrosol and preehit wettable powder.The control effect on tomato leaves treated by 0.5,1.0,2,3.0 g/L SiO2 hydrosol and 500 times 75% preehit wettable powder was up to 43.34%,55.03%,60.46%,55.75% and 58.18% respectively after 7 d.For leaf mold of indoor potted tomato,it was up to 12.47%,17.79%,43.61%,24.61% and 41.85% respectively after 15 d.It indicated application 2 g/L SiO2 hydrosol was the best treatment to control leaf mold of tomato.
