Abstract: For selecting more effective chemicals to control TMV, the field control effect experiments of Duxiao at a dilution of 600, Ribaririn at a dilution of 500, amino acid at a dilution of 300, and photosynthesis bacterium at a dilution of 500 (foliar fertilizer) were conducted.The results showed that the control effects of Duxiao at a dilution of 600 was 73.24% in the initial stage of TMV, and that of Ribaririn at a dilution of 500 was 75.90% while started application in the metaphase of TMV, the effects of all these chemicals were decreased thereafter.The control effects of amino acid and photosynthesis bacterium were worse.
