A method for biological control of the number of pests of vegetable crops by consecutive saturation of an agrocenosis, in the optimum periods, with entomophages artificially grown in laboratories, at experimentally substantiated settling rates per 1 ha. Due to the absence of stress conditions, chemical and other insecticides, entomophages artificially settled, together with natural populations effectively, along the vegetation, control the balance in the "parasite - host" system at the level safe for plants. Such a combination of three entomophages effectively supplements regulatory functions weakened in the agrocenosis that allows protecting vegetable yield by biological techniques only. |
