Native Fungi and Actinobacteria Identified in Southern Vietnam as Potential Biocontrol Agents Against Fusarium Wilt in Bananas

Researchers in Southern Vietnam have identified native fungi and actinobacteria as potential biocontrol agents against Fusarium wilt, a disease that severely impacts banana crops worldwide. The study, conducted by a team including Tran V.T., Dinh T.Q., and Le D.D., highlights the ability of these microorganisms to target *Fusarium oxysporum* f. sp. *cubense* tropical race 4 (TR4), the pathogen responsible for the disease. This discovery could provide an alternative approach to managing the destructive effects of Fusarium wilt on banana plantations.

The collaborative research focused on isolating and testing native strains of fungi and actinobacteria from local environments in Southern Vietnam. These microorganisms demonstrated significant antifungal activity against TR4 in laboratory conditions, suggesting their potential role as natural biocontrol agents. Fusarium wilt, caused by TR4, has been particularly challenging to manage due to its persistence in soil and resistance to chemical treatments. The findings offer insights into sustainable agricultural practices that could mitigate the impact of this disease on global banana production. Further studies are expected to evaluate the field application and long-term effectiveness of these biological agents.
