[Effect of Chaetomium cochliodes Palliser on micromycetes of the root zone of spring barley].
The paper deals with the studies in species composition of micromycetes of the meadow-chernozem deleached soil in the root zone of spring barley and their interaction with the strain of fungus-antagonist Chaetomium cochliodes 3250, which served a basis for creation of the preparation--chetomik to protect plants from the root diseases agents. Differences were established between mycobiota of soil and root zone of plants; the most considerable ones are the differences between soil rhizoplane: the decrease of special diversity, changes in the number composition of numerous micromycete species. It has been shown that Chaetomium cochliodes 3250 manifests high antagonistic activity with respect to saprophytic and, especially, phytopathogenic fungi isolated from soil of spaces between rows, rhizosphere as well as rhizoplane of the spring barley which evidences for expediency of this strain use as the means of the culture protection from the root rots.
