Abstract:

The article presents data on the screening of rhizobacteria and active isolates isolated from the humus layer of natural humus soils against phytopathogenic fungi Rhizoctonia solani and Fusarium oxysporum and their resistance to various concentrations of NaCl (0%, 1%, 5%, 7%, 10%). The results of studies on the synthesis of phytohormones with the properties of microorganisms that enhance plant growth and development are presented. Antagonistically active bacterial strains that grew even at high salt concentrations were identified using MALDI-TOF analysis. They were identified as XD 4.3 Bacillus subtilis and XDN6 Bacillus cereus, respectively.
