Abstract:

The injured and un-injured root of banana seedlings were drenched with the bacterial broth of mixed, antagonist and non-antagonist which were isolated from the bean pulp fermentation bacterial broth for investigating the effect on control banana wilt pathogen-Fusarium oxysporum f. sp. cubense race 4 (Foc4). The results showed that all of bacterial broth had varying degrees of effect in control banana wilt pathogenicity, in which, drenching roots with mixing bacterial broth had the best control effect at 94.3%, stimulating activities of Pro, SOD and POD, and also inhibited synthesis of MDA simultaneously.
