The article presents the results of research in 2021-2023 regarding the control of the population density of the Colorado potato beetle (Leptinotarsa decemlineata Say.) on plantings of potatoes of the Myroslav variety under a one-time spraying with insecticides and the impact on the formation of crop yields. The influence of modern insecticides Koragen® 20 CS (chlorantraniliprole, 200 g/l) and Ampligo® 150 ZC, (chlorantraniliprole, 100 g/l + lambda-cyhalothrin, 50 g/l) on the number of Colorado beetle larvae (L1-L4) was investigated. in the conditions of the Kyiv Region, Belotserkiv District. During 2021-2023, the first instar larvae of the Colorado potato beetle appeared in the 1st - 2nd decades of June, and the mass appearance of the larvae of the pest occurred during the month. According to records made before spraying, the number of larvae of the Colorado potato beetle averaged 15.2 specimens/plant. Based on the data obtained during 2021-2023, the technical efficiency of the studied drugs against the larvae of the pest for two weeks was at the level of 100% compared to the control, the number of individuals on which during this period reached 44.4.4 specimens/plant, with the use of Dantop 50, HV on average - 5.9 copies/bush. It was noted that chlorantraniliprole has the ability to maintain a toxic effect not only on plants, but also on the soil surface for more than two weeks, which makes it impossible for beetles and pest larvae to migrate from the surrounding areas, because upon contact with the active substance, the insect immediately "paralyzes" and after 2-3 days she dies. The use of insecticides affected the formation of tuber productivity. Thus, the highest rate of preserved harvest was noted for the use of the drugs Koragen® 20 CS and Ampligo® 150 ZC at the level of 24.1 t/ha and 23.7 t/ha, respectively, compared to the control (without the use of insecticides). At the same time, on the variant with the reference insecticide Dantop 50, WG, this indicator was at the level of 14.9 t/ha, which is almost twice as low as compared to the areas where Koragen® 20 CS and Ampligo® 150 ZC were used.
