ABSTRACTududAntagonism of Pseudomonas fluorescens Migule. from soil and rhizospheres of banana, chilly and corn on Fusarium oxysporum f.sp. cubense (E.F.Sm) Sdny the banana’s wilt pathogen. The objective of this research was to study antagonism of Pseudomonas flourecens spp on the growth of Fusarium oxysporum the banana’s wilt diseases pathogen. The research was conducted at Phytophatology laboratorium at the Plant Pest and Diseases Departement, Faculty of Agriculture, Sriwijaya University. The treatments were arranged in completely randomazid block design (CRBD) with seven treatments and three replications. The treatment were: three isolate Pseudomonas flourecens from the rhizosfer of healthy banana (A, B and C); 2 isolate Pseudomonas flourecens from rhizosfer of healthy maize (D and E); 2 isolate Pseudomonas flourecens from healthy chilly (F and G). Results of the study showed that Pseudomonas flourecens from rhizosfere of healthy maize were the best antagonism on Fusarium oxysporum development as compered to other treatments. The decline of antagonism zone was very clear at fist 4 till 6 day, but it was stable at 10 days of observation.ududKey words: Antagonism, Pseudomonas flourecens spp,Bacilus subtilis, Fusarium oxysporum. udud
