| Abstract | Pisang Awak is one of the most important banana cultivars due to its drought tolerance and nutritional value. Nonetheless, Pisang Awak is highly susceptible to Fusarium wilt caused by Fusarium oxysporum f.sp. cubense (Foc). Over the past decades, the use of biocontrol bacteria against Foc has shown promising results in both greenhouse and field trials. However, none of these previous studies demonstrated effective control of Fusarium wilt in Pisang Awak. We show that Pseudomonas and Bacillus strains isolated in Thailand can suppress Foc mycelial growth in vitro and significantly mitigate the severity of Fusarium wilt in Pisang Awak (Namwa) banana in a greenhouse experiment. With these bacterial treatments, Fusarium wilt incidences can be reduced by up to 70% and 89% in young and old banana plants, respectively. We have also reported the first bacterial community analysis of Pisang Awak rhizospheres in response to Foc and bacterial biocontrol. The abundance of several bacterial families such as Rhodospirillaceae, Bradyrhizobiaceae and Hyphomicrobiaceae increased in rhizospheres inoculated with Foc and decreased in rhizospheres treated with biocontrol. These families were previously shown to be associated with Foc suppressive soil. These results provide the basis for the development of bacterial biocontrol products against Foc in Pisang Awak banana. |
