Herbicides in soy crops

The aim of the research was to study modern herbicides in soybean crops, as well as drugs influencing the crop positively. The research objects were soybean varieties of the local selection Svapa, Lancetnaja, Mezenka; herbicides Dual Gold, Gezagard, Fjuzilad Forte, Basagran, Frontier Optima, Aramo 45, Harmony Classic, Harmony, Algorithm; regulators of growth based on taxifolin, seaweed extract, acetylene alcohol, living microorganisms Bradyrhizobium japonica, lipohitooligosaharid+Rhizobium leguminosarum. Field and production experiences were carried out in 2011-2017 in the Orel and Pokrovsky areas of the Orel region. High biological efficiency was determined during the experiment - 96% of herbicides Dual Gold and Gezagard in 40 days after they were applied when the number of weeds under control was 125 cop/m2 gave grain yield 1.9 t/ha. With high contamination of crops with weeds of Poa bloodline (up to 450 cop/m2) the applicaytion of Doual Gold under the preplanting cultivation and graminicida Fjuzilad Forte on the growing weeds showed an efficacy 98%, which increased the productivity of grain 0.75 t/ha. The application of herbicides Harmony Classic or Harmony helped to increase yields by an average of 0.4 t/ha. The consistent application of herbicides Dual Gold or Frontier Optima, then Bazagran, Fjuzilad Forte or Aramo 45 helped to receive grain yields 2.44 -2.28 t/ha. The research showed that seed treatment with drugs on the basis of taxifolin, seaweed extract, alcohol acetylene and others increased germinating energy by 5%, similarity by 3-8% and increased yields by 0.16 t/ha or 10.1%. The combination of treatment and seed processing of plants during the growing season with biological stimulators increased yield by 0.22-0.24 t/ha or by 19%, and preplanting cultivation and two processing during the vegetation period (phase budding and flowering) increased yields by 0.31 t/ha or by 24.4%.
