Field observation on control of tobacco mosaic virus (TMV) with chemicals
Kunming Tobacco Company, Kunming, China.
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.
