Abstract: In order to select more effective virus inhibitors, field experiments on TMV control with 5 virus inhibitors were conducted in China Tobacco Northeast Agricultural Test Station in 2002 with YC/T40-1996 tobacco disease chemicals effect test method, the disease index and control effects were calculated. The results showed that the control effects of 3.95% Ribaririn at a dilution of 500, 22% Jinyebao at a dilution of 400, 24% Duxiao at a dilution of 1000, Jingtuling at a dilution of 600, and Xiaodulitao at a dilution of 800 were 62.47%, 57.83%, 57.60%, 46.42% and 39.40%, respectively.
