Decomposition of thiamethoxam in its combined use with hydroxycinnamic acids on potato and currant

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