Varieties of vegetable diseases and more serious harm to the current production of various preparations of tomato prevention and control, sweet (spicy) pepper and other virus diseases have a better control effect. We introduce the following: 1. Weakly vaccinated N_ (14) N_ (14) was inoculated to tomato by weak mutants of tobacco mosaic virus (TMV) developed by chemical mutagenesis, such as Tian Bo and Zhang Xiuhua, Institute of Microbiology, Chinese Academy of Sciences. Sweet (spicy) pepper body, so that it has an immune effect, can be caused by tobacco mosaic virus infection caused by tomato, sweet (spicy) pepper virus disease. Disease index fell more than 50%, at the same time there is thorns
