Acinetobacter sp. GET13 Strain as a Biological Agent for Protection of Plants against Phytopathogenic Bacteria and Fungi

The use of chemical pesticides in agriculture leads to the accumulation of harmful compounds in soil and plants that can cause diseases of humans and animals. The biological method of plant protection is a promising alternative to chemical pesticides. The purpose of this study was to analyze the antagonistic activity of the Acinetobacter sp. GET13 strain against common bacterial and fungal pathogens of plant diseases in in vitro and in planta experiments. As a result, the effect of the bacterium on the growth of phytopathogenic bacteria (Clavibacter michiganensis, Erwinia carotovora, Pectobacterium carotovorum and Pseudomonas syringae), as well as phytopathogenic fungi (Helminthosporium sativum, Piricularia oryzae.) that cause serious damage to agriculture, was studied. To confirm the results obtained in these experiments, an in planta experiment was conducted on Phaseolus vulgaris (L.) The effectiveness of Acinetobacter GET13 strain for plant protection against phytopathogens was proved based on the results of taking into account the linear function between weight and volume parameters of plants at the end of the experiment. Therefore, this strain has the potential to create a biological product.
