Antagonistic properties of rhizobacteria in relation to phytopatogens of wheat

Abstract

The aim of our research was to study the antagonistic activity of rhizobacteria in relation to wheat phytopathogens. The objects of research were local active strains of phosphate and potassium-mobilizing wheat rhizobacteria of the genera Rahnella, Enterobacter, Pantoea, Pseudomonas, Bacillus and phytopathogenic wheat fungi. As test cultures in determining the antagonistic properties of rhizobacteria, 6 strains of phytopathogenic fungi (Fusarium graminearum, F. oxysporum, F. tricinctum, F. avenaceum, Bipolaris sorokiniana, B. spicifera) of wheat were taken from the collection of the Institute of Genetics and Experimental Plant Biology of the Academy of Sciences of the Republic of Uzbekistan. The antagonistic activity of rhizobacteria against phytopathogenic wheat fungi was studied by the well diffusion method on Czapek's medium.
