Tobacco wilt disease is soil-born disease caused by Ralstonia solanacearum, which occurs in temperate and subtropical major tobacco-producing region. In order to study the effect of different soil types and tobacco varieties on the incidence of tobacco wilt disease, a higher concentration of gradient dilution(1.0×105-9 CFU/mL) of Ralstonia solanacearum was used to inoculated to K326 and Yunyan 87 varieties(Resistance:K326>Yunyan87) with irrigation method, which is grown in paddy soil, fluvo-aquic soil, purple soil and red soil, respectively. The effect of pathogen amount, soil type and varieties on the incidence of tobacco wilt disease were investigated
