One of the obstacles that was encountered in the banana cultivation is blood disease. Blood diseases is caused by
Ralstonia solanacearum that is subsequently revised to become blood disease bacteria (BDB). Until now the control
of banana blood disease is very difficult. Control of banana blood disease with chemical injections and soil treatment
is not effective. This study was aimed to obtain Kepok Kuning cultivar banana seedlings which was resistant towards
blood disease obtained from in vitro selection by using BDB growing filtrate and induced resistance by inoculation of
antagonistic endophytic bacteria.The observation of Kepok Kuning banana explants treated with various concentrations
of BDB growing filtrate showed that the percentage of living explants decreased to 83.33% when the BDB growing
filtrate concentration increased to 15%. Treatment of banana explants with BDB growing filtrate also affected the
number of roots, shoots, and leaves. Treatment with a single antagonistic endophytic bacteria suppressed the intensity
of banana blood disease to 0% in comparison with the mixture of antagonistic endophytic bacteria if Kepok Kuning
banana explants were not treated with BDB growing filtrate. When Kepok Kuning banana explants were treated with
BDB growing filtrate, the intensity of banana blood disease suppressed to 0% after the high concentration of BDB
growing filtrate and the antagonistic endophytic bacteria mixture were applied.
