Description
Summary:	New substances on the basis of soil streptomycete Streptomyces avermitilis metabolites and also compositions of preparation averkom with elicitors show growth regulating activity and bioprotective properties, proved in experiments with wheat spring of variety Grizo and cucumbers of variety Nezhinskiy. Most of the created substances possess the antagonistic action in relation to phytopathogenic fungi, as well as antinematode activity in relation to the gallic nematode Meleodoidyne incognita. In the conditions of the artificial nematode infecting the preparation averkom and its modifications demonstrate protective action (up to 85-100 %) on cucumber sprouts of Nezhinskiy variety. The considerable differences were found out in the index of homology percentage between small regulatory RNA (si/miRNA) and mRNA of experimental (that were treated by substances on the infectious background) and control cucumbers, and wheat plants.
