Master's work application of pathogens actinomycetes in some potato diseases caused by phytopathogenic bacteria. The work is presented on 55 pages. It contains an introduction, a literary review, an experimental part with its tables and illustrations, applied literature. The aim of the work was the identification of actinobacteria from potato soils and the identification of antagonists against pathogenic bacteria – Ralstonia solanacearum, Clavibacter michiganes ssp.sepedonicus and Dickeya solani ,identification of antagonistic actinomycetes against phytopathogenic bacteria. Among the diseases caused by phytopathogenic microorganisms, diseases of potato bacteria are important: brown rot, ring rot and wet rot. Despite the existence of many pesticides, there are still many undefeated and poorly controlled diseases of plants. Therefore, it is actual to use of bio medications an alternative to chemical pesticides as an antimicrobial agent. At the same time, the biological method of protection against plant diseases are microorganisms, whose action is based on the antagonistic interaction of microorganisms Actinomycetes are one of the most important soil micro flora groups. They are products of many antibiotics and enzymes that form the basis for their use against phytopathogenic microorganisms. Based on the work carried out in the soil of Georgia, in a certain ecological environment actinocytes are revealed. Antagonists identified to wards phytopathogenic bacteria - Ralstonia solanacearum, Clavibacter michiganes ssp.sepedonicus and Dickeya solani, are the basis for bio-pesticides to combat potato diseases. The newly formed actinomycetes belong to the following species: Streptomyces, Nocardia, Streptosporangium. The use of antagonistic actinomycetes will support not only to large-scale harvesting and getting high-quality products, but also it is an irreplaceable option for the natural balance of the soil.
