In this study, the possibility of the combination of endophytic bacteria () and oligochitosan as a suppression effect of tomato bacterial wilt was investigated. As a result, the independently treatment of oligochitosan was not exhibited the tomato bacterial wilt suppression effect. The enhancement of the tomato bacterial wilt suppression effect by the combination of oligochitosan and bio-pesticide also was not observed when tomato was treated at same time. On the other hand, the suppression effect against the pathogen significantly increased when the bio-pesticide-treated tomato was handled with oligochitosan before transplant to soil contaminated by the pathogen. This result strongly suggests that the oligochitosan enhances the suppression effect against pathogen in tomato which already was induced the resistance by bio-pesticides.

The endophytic bacteria produce various kinds of bioactive substances, by which the plants grow well and exhibit resistance to diseases and environmental stress. In this study, 300 isolates that were derived from FPH9601 irradiated with carbon ion beams were tested for inhibitory effect of tomato bacterial wilt. We could successfully obtain 24 mutants that have enhanced suppressiveness against the tomato bacterial wilt. In the meantime, chitosan is a linear polysaccharide composed of randomly distributed 
-(1-4)-linked D-glucosamine (deacetylated unit) and N-acetyl-D-glucosamine (acetylated unit). Low molecular weight chitosan (oligo-chitosan), which can be obtained by 
-ray irradiation of chitosan in diluted solutions, has potential uses in agriculture. In the field condition, the suppression effect against the pathogen significantly increased when tomato was treated with oligo-chitosan and endophytic bacteria.
