Modern intensive crop production is unthinkable without the use of fertilizers, growth regulators, taking into account the key phases of plant ontogenesis, control number of pests and development of diseases, activation of useful micro and macro-organisms. Synthesis of the necessary substances in some cases advantageous to (cheaper, more efficient) does not produce chemical and biological way, involving animals, plants (or their culture cells and tissues) and microorganisms. Benefits of organic substances, metabolites of living beings to pesticides and chemical fertilizers - is their comprehensive affirmative action and high efficiency that allows you to make biological products in minimal doses. As natural substances, they do not accumulate in the environment and are easily utilized therein.
Between plants and inhabiting their surface epiphytic micro-organisms can develop a variety of symbiotic relationship. Microorganisms obtained from plant organic matter and sometimes the water, and they can bring benefit to the plant (a mutually beneficial symbiosis - mutualism), damage (parasitism), or do not have a significant impact on it (spongering – commensalism). At the same time between the epiphytic micro-organisms arises competition for power supplies, and the healthy development of the plant inhibits the pathogenic microflora is normal (usually releasing antibiotics). Therefore, when adjusting the power and protection components microbial problem arises as before can take place on the plant and its root system in the rhizosphere of plants for the development population of beneficial microflora.
The plant is used as a microbial mass (live or spore form), and metabolites of microorganisms (biologically active substance). In rare cases, the culture liquid is not separated, and use the two components together (microbiota and substance).
