Biocontrol efficacy and impact on the rhizosphere community structure of Bacillus cereus CH2 against verticillium wilt on eggplant in the field condition

Abstract:

In this study we aimed to evaluate the biocontrol efficacy of Bacillus cereus CH2 against Verticillium wilt on eggplant in field condition and its influence on rhizosphere microbial community structure. Based on the results we can make a conclusion that Bacillus cereus CH2 could reduce the desease incidence of Verticillium wilt on eggplant at 60.6%. The Biolog data showed that inoculating of CH2 had no significant impacts on the diversity of microbial community in rhizosphere. It also showed that its inoculation could increase utilizing ability of five groups of carbon sources except the phenolic compounds during the early growth stage of plants.
