Antagonistic activity of dominant strains of bacteria of spring barley rhizosphere against phytopathogenic micromycetes
The purpose of the work. The aim of the study was to conduct research on the manifestation of the dominant representatives of the bacterial biome of the rhizosphere of spring barley antagonistic activity against phytopathogenic micromycetes. Research methods. The standard diffusion method of double culture in Petri dishes was used to study the antagonistic properties of the dominant strains of rhizosphere bacteria. The level of antagonistic activity of microorganisms was assessed by the indicator (%) of inhibition of growth and development of the mycelium of micromycetes Fusarium sporotrichioides Sherb. 23.2, Alternaria alternata (Fr.) Keissl. 3.45, Nigrospora oryzae (Berk. & Broome) Petch. 18.77. Results and scope of their application. Studies have shown that Bacillus methylotrophicus 10 had an inhibitory effect on Fusarium sporotrichioides Sherb. 23.2 ‒ 77,4%, Alternaria alternata (Fr.) Keissl. 3.45 – 66,6% and Nigrospora oryzae (Berk. & Broome) Petch. 18.77 – 86,7%, while the bacteria Phyllobacterium ifriqiyense 1 showed activity against phytopathogens by 45,1%, 63,1% and 65,0%, respectively. Conclusions. Thus, both strains of rhizosphere dominant bacteria have high antagonistic activity against phytopathogenic micromycetes, which gives grounds for their further study.
