Biopreparations as an agro-ecological factor enhancement of biosafety in agrocenoses

Abstract

The problem of environmentalization of agricultural production is extremely important in a scientific and applied sense, the main task of which is to provide the population with food products, prevent crop losses from harmful objects, and protect the environment from excessive chemical load. Accordingly, an alternative solution in overcoming the negative consequences of chemicalization of agricultural production and improving the quality of seed products is the use of environmentally safe plant protection measures. Protection against phytopathogenic microorganisms is an important component of technologies for growing various crops. After all, in soybean agrocenoses there is an accumulation of an infectious background of phytopathogenic micromycetes, among which species of the genus Penicillium, Aspergillus, Alternaria, and Fusarium predominate, which can cause outbreaks of many plant diseases (root rot, Alternaria, Fusarium, late blight, anthracnose, cercosporosis). Phytotoxic metabolites of necrotrophic phytopathogenic fungi, which are able to accumulate in soil, seeds and plant residues, deserve special attention. After all, mycotoxins lead to a decrease in the yield and quality of grain, as well as the quality of food products, which negatively affects their ecological safety, and this, in turn, can cause poisoning of humans and animals. The use of biofungicides is aimed at controlling diseases and reducing their harmful effects. Seed treatment leads to disinfection of seed material and protection of young plants from various infections. Therefore, the use of useful microorganisms, which are part of biological preparations, which effectively affect the processes of functioning of agroecosystems, is relevant.
