Abstract

A detailed study was conducted to find out the efficacy of Pseudomonas fluorescens on fusarial corm rot pathogen Fusarium oxysporum f. sp. gladioli in Department of Plant Protection, Allahabad Agricultural Institute Deemed-University, Allahabad. The strains of P. fluorescensisolates from gladiolus rhizosphere had significantly inhibited the growth of F. oxysporum f. sp.gladioli. Among the strains, PsL-4 of P. fluorescens has higher inhibitory action in comparison with other strains. The strains of P. fluorescens also produced hydrogen cyanide (HCN) which limited the growth of pathogen. The study also indicated the involvement of Siderophore-mediated antagonism in P. fluorescens.

 

Key words: Fusarium oxysporum, gladiolus, Pseudomonas fluorescens, siderophore antagonism.
