The potential endophytic fungi from healthy banana root as promising biocontrol agents to control Fusarium wilt banana disease caused by Fusarium oxysporum f.sp. cubense.

Roots of banana are colonized by various populations of microbes that potential as biocontrol agents for various soil-borne plant pathogens. One of the most important and destructive diseases on banana is Fusarium wilt caused by Fusarium oxysporum f sp cubense (Foc), causing decreased yields and death plants. Once Foci is present in the soil, it is hard to be eliminated. Collecting root samples was done with Purposive Randomize Sampling. The result of the study found 35 endophytic fungal isolates with different physiology and morphology. On the inhibition test in vitro, showed only 6 isolates could be promising as bio control agents. Those were PA 2.3,, PB 2.1, PD 2.2 and PE 2.2 isolates) that identified as Trichoderma spp and they had ability to suppress the growth of Foc with very high competition, invasion and parasitization, and the other two isolates identified as Aspergillus sp (PA 2.1 and PB 1.6 isolates) showed clear zone which also have potentials to inhibit the growth of FOC with antibiosis mechanism.
