An antagonistic bacterium WJB0802 against tomato bacterial wilt and its application

In this study, the effective antagonistic bacteria with in vitro antibacterial activity against pathogenic Ralstonia solanacearum were isolated from the rhizosphere of healthy tomatoes in the diseased fields by using plate co culture and rapid screening of hydroponic rhizosphere, and their classification status was analyzed by 16S rRNA gene sequencing. The results of greenhouse test showed that WJB0802 significantly reduced the disease index of tomato bacterial wilt by 67.9%, and the control effect reached 71.57%.This study provided a new strategy for establishing model biological strains to prevent and control tomato bacterial wilt.
