Suppression of Fusarium wilt of banana with an application of Trichoderma asperellum inoculants

[摘要] Fusarium wilt is one of the most serious diseases of banana plants in Malaysia that now becomes a worldwide problem. It is caused by soil-borne pathogen Fusarium oxysporum Schlecht f. sp. cubense (E.F. Smith) Snyder & H.N. Hansen. In this study, in vitro and in vivo experiments were conducted to evaluate the effects of Trichoderma asperellum B01 inoculants on disease incidence of Fusarium wilt of banana. Results indicated that percentage inhibition of radial growth (PIRG) was observed in dual culture plates of Trichoderma isolates B01 by 84.85%. In addition, under plant house condition, the application of conidial suspension of T. asperellum B01 has significantly decreased the incidence rate of Fusarium wilt by up to 94.4% compared to control. In general, the application of T. asperellum B01 inoculants revealed a great potential for the control of Fusarium wilt disease in banana plants under plant house condition, which a good approach to start in agricultural field. For future study, new method must be focusing on optimize the production of Trichoderma spores to be using for agricultural purposes.
