INTERACTION BETWEEN ANTAGONISTIC BACTERIAL ISOLATE PSEUDOMONAS MONTEILIIVK58 TO BACTERIA ISOLATED FROM SOIL

Abstract

The use chemical drugs in protect tomato from bacterial wilt disease was not fullyeffective, so the study microorganisms that can antagonise Ralstonia solanacearum - it causedbacterial wilt disease on tomato - is very necessary, because these microorganisms are safe f,¥environment, effect in protect crops from bacterial wilt disease, but to evaluate the interactionbetween antagonistic bacterial isolate Pseudomonas monteilii vk58 to bacteria isolated from soilis needed.The result have followedThe Pseudomonas monteilii vk58 isolate can resistant in soil during 30 days andinhibit growth of R.solanacearumBacterial isolates showed the antagonistic ability in the mix form to be weaker thesingle form.The Pseudomonas monteilii vk58 isolate can R. solanacearum strong inhibit bothforms the mix and single, that can satisfY the demands of a bacterial isolate to produce thebiological product to use in protect tomato from bacterial wilt disease.These results suggested that the biological product was produced from antagonisticbacteria that can be used widely in the agricultural, to create a green, clean environment, haven'tgot chemical drugs.
