This article summarizes the data on the mechanisms of influence of rhizosphere bacteria to plants. Are the data of the Russian and foreign authors on the role of growth stimulating rhizobacteriain agriculture. The study of symbioses currently occupied a priority in a number of topical problems in modern biology. Numerous experimental data indicate that the symbiotic associations represent one of the primary forms of existence of the organisms in the biosphere. On the basis of associative rhizobacteria developed many methods of struggle not only with «traditional» obligatephytopatogens, but also the so-called polymorphic groups of fungi, including as saprophytic and parasitic forms, many of which are known as biodestructor, pathogens cultural and wild plants. Antagonistic activity is also used for the development of methods of growth stimulating plants have rhizobacteriadifferent mechanisms of positive influence on plants.
