Influence of biological preparations on ordinary root decay of the vegetable string bean

In this research work the estimation of efficiency of the experimental biological preparations against root rot of the green bean under the laboratory and field conditions was given. Two species of Fusarium fungi were isolated from root system of the green bean and the experiment of studying the inhibitory activity of the biopreparations under the laboratory conditions on the pure cultures of these fungi was performed. Also registration of influence of the biopreparations on the root rot severity and yield of green bean was performed.
