Abstract

A method for protecting vegetable maize from aphis populations includes settling laboratory populations of entomophages onto plants. Along the perimeter of a plot where maize was grown, in two terms, in particular in early May dill is sown with an interval of 17-20 days. In addition, in the period of appearance of the first aphis colonies on plants foliar fertilizing of the maize with aqueous solution of the fertilizer Riverm is carried out in an equivalent of 15 l per 300 l of water per 1 ha. Furthermore in 11-12 days after the first fertilizing, the second one is carried out by a mixture of 0.12% superphosphate and 0.07% potassium chloride. Moreover, in the period of appearance of the aphis feeding on maize roots double settling of caterpillars of the third age of the common lacewing (Chrysopa carnea Steph.) is carried out with an interval of 9-10 days onto the soil surface in the area of root collar of the maize in an equivalent of 40-45 individuals per one plant.
