Abstract :Fusarium oxysporum f.sp. dianthi insert ignore into journalissuearticles values(Fod); causes severe wilting on carnations in Turkey. In order to control of carnation vascular wilt disease, 311 fluorescent Pseudomonads were isolated from the roots of carnation plants and the bacterial strains were tested for in vitro antagonism with Fod in plate tests. Fifty nine strains were evaluated and five strains found to suppress Fusarium wilt of carnation in pot bioassays. Antagonistic bacterial strains S53 and S54 were identified as Pseudomonas putida; I20, U34 and U73 as Pseudomonas fluorescens
