The experiments were conducted in the city of Moscow, on the territory of the Educational, Scientific, and Production Center named after V. I. Edelstein “Michurinsky Garden” FSBEI HE “RSAU-Moscow Agricultural Academy named after K.A. Timiryazev” and Field experimental station in the period 2021-2022 on the black currant and potato plantings. Laboratory analysis of plant material samples for the study of the content of residual amounts and determination of the dynamics of pesticides destruction was carried out in the Educational, Scientific, and Consulting Center “Agroecology of pesticides and agrochemicals”. The following preparations were used in the tests: insecticide − Actara, VDG (250 g/kg of thiamethoxam) and growth regulator − Zircon, R (0.1 g/l of hydroxycinnamic acids). In the conditions of the experiments, a separate application of the preparation Actara, VDG and its combined use with the preparation Zircon, R to establish the level of residual amounts of the insecticide Actara, VDG active substance, sampling was carried out within 21 days from the moment of spraying on all experiment options. The selected samples were analyzed under laboratory conditions using the high-performance liquid chromatography method. As a result of the study, it was found that the use of Actar, VDG together with the preparation Zircon, R on black currant plantings caused an acceleration of the destruction of the insecticide active substance in the leaves. Nevertheless, the combined use of the studied preparations did not reduce the level of thiamethoxam intake in the forming black currant berries. The use of the preparation Actara, VDG together with the double use of the growth regulator Zircon, R on potato plantings led to accelerated decay of thiamethoxam in the tops and less of its accumulation in tubers.
