As a result of the conducted studies, a number of strains of aerobic spore-forming microorganisms were selected, which were characterized by high antagonistic activity against phytogenic bacteria and fungi of the disease pathogens Gossypium hirsutum. The presence of a number of compounds with antagonistic, restimulatory (stimulatory phytohormones and inhibitory phytohormones), and elicitor activities (phenolic compounds, dicarboxylic acids, volatile organic compounds (VOCs)) in the exometabolome of selected strains was shown. In addition to changes in morphometric parameters, changes in the metabolome of G. hirsutum under the action of the studied preparations were detected. An increase in the levels of 4-aminobutyric acid, which is a stress protector and signaling molecule, in plants treated with the biopreparation was shown. Product Description popup.authors Maksym A.
