The using of bio preparations against summing pests (thrips and aphids) in growing winter wheat

The results of using biopesticides on winter wheat against thrips and aphids are presented. It was determined that pre-sowing treatment of seeds with biological preparations does not lead to a change in the number of thrips and aphids. To control their number, it is advisable to use bioinsecticides: against aphids, the most effective was the triple use of a mixture of 3% solutions of Lincomycin BT + Bezimid BT (1:1), where the efficiency was 83.3%, and the effectiveness of biological preparations against thrips ranged from 40.6% to 55.8%. The combined use of biological and chemical insecticide increases the effectiveness of the biological preparation while reducing the chemical load. Early sowing of winter wheat contributes to increase in the population of imago plants and thrips larvae and, to a lesser extent, aphids.
