THE APPLICATION OF EXOGENOUS ELICITORS IN AGRICULTURE
In recent years, there is an increasing in crop losses from pests and diseases of plants worldwide. The use of different pesticides in intensive cultivation technologies of winter wheat can not resist it. Pathogenic microorganisms acquire resistance to drugs used and become more aggressive. This creates a lot of environmental problems. Plants are almost always under environmental stress. In this state, they are immunodeficient. However, it is impossible to reject pesticides completely. But pesticides are not able to replace the immune system of the plant, and in some cases are suppressing it. The article provides an overview of commonly used exogenous elicitors. We discuss the most important results of the joint use of the composition of preparations of eliciting action which are furolan and methionine. The present level of development of science has led to the emergence of new methods of plant protection, which is based on increasing the capacity of the immune plants, rather than the destruction of pathogens, as in the case of the use of pesticides. The yield increase by the use of biogenic elicitors as immunizers from 10 to 30% depending on the year, the varieties of plants and especially on infectious pathogens. The elicitors are used for soil treatment, seed soaking and plants, spraying the plants during the vegetation
