An Experimental Study on the Application of Vaccine N_(14) of TMVt_(ts) and Satellite RNA Bio-Control Preparation CMV-S_(52) for the Control of Tomato Virus Diseases

The results of the experiments in 1983—1986 showed that the combined use of vaccine N_(14) of TMV_(ts) and satellite RNA bio-control preparation CMVS_(52) can effectively prevent tomato plants from infection of TMV and CMV. The experiments in the past four years proved that the rate of disease in the immunized tomato plants dropped by 25.2～45.4％, the disease index dropped by 16.1—31.3 and the yield increase reached 22.3—44.9％ per mu. In 1986 the total representative areas in Shanxi province was about 958 mu...
