Field Experiments on Control of Tobacco and Cucumber Mosaic Virus Diseases with Virus Inhibitors

In order to select more effective virus inhibitors to control tobacco and cucumber mosaic virus diseases (TMV and CMV), field experiments on control effects of 8 main commercial chemicals and 4 kinds of plant extraction from Phytolacca acinosa, Rumex japonicus, Isatis tinctoria and Lentinus edodes were conducted.The result showed that 2% Ningnanmycin AS and 40% Enadenine Oxyenadenine WP had significant prevent effects, 3.95% Ribaririn WP, 40% Enadenine Oxyenadenine WP, the ethanol extractions from Phytolacca acinosa and the water extractions from Lentinus edodes had some control effect.
