Prevention of phytophag proliferation in sugar beet crop rotation

Abstract

Purpose. To examine the efficiency of cultivation technology for sugar beet and localization of insecticides on the seeds in order to prevent mass propagation of herbivores.Methods. Field, laboratory-field, analytical, statistical.Results. Under the conditions of Uladovo-Liulynetska RBS, the best preceding crops of sugar beet that provided positive effect on reducing the number of herbivores and their damage were rape, sunflower, and fallow Under the conditions of Veselopodilska RBS, beetroot weevil and beet flea damaged young plant after winter wheat, while after fallow the damage was minimal. For plant mineral nutrition, under the conditions of Uladovo-Liulynetska RBS the number of beet in normal conditions ULRBS N120P80K120 a reduced number of beetroot weevil and beet beetle. Ploughing to a depth of 30–32 cm leads to increase in drilling beetle and reducing population density. The number beet flea beetles and weevils were the same in all the treatment of the experiment. When treating sugar beet seed with the insecticide Cruiser 600 FS 30 days after the sprouts appearance, the effectiveness against beetroot weevil was 81.4 %.Conclusions. To prevent the mass reproduction of herbivores in crops of sugar beet, crop rotation is recommended along with balanced plant nutrition and soil tillage methods, treating the seeds with insecticides of systemic and contact action.
