Golubev, A.S. | Borushko, P.I.
Trials with herbicide Bison Advance (350 g/l bentazone and 2 g/l tifenesulfuron methyl) were carried out for two years (2018 and 2019) in 3 climatic regions of the Russian Federation (Altai, Krasnodar, Astrakhan). Experiments were laid out in accordance with "Guidelines for registration trials of herbicides in agriculture" (2013). Efficiency 1.5 l/ha herbicide Bison Advance in the conditions of Krasnodar and Astrakhan regions exceeded efficiency of 1.5 l/ha of standard Bizon (480 g/l bentazone). In the Altai region efficiency was at the standard level. Efficiency 2.0 l / ha and 2.5 l/ha herbicide Bison Advance was at the level of effectiveness of 3.0 l/ha of standard, and in some cases exceeded the standard. Using the 2.5 l/ha herbicide Bison Advance in the conditions of the Krasnodar region clear soybean crops from all annual dicotyledonous weeds. Herbicide Bison Advance was more effective than the standard: to Amaranthus retroflexus L. on average by 14-33%, Chenopodium album L. - 18%, Ambrosia artemisiifolia L. – 17-19%, Xanthium californicum Greene – 15-17 %, Persicaria maculosa S.F. Gray – 34-50%, Solanum nigrum L. – 4-28%. The use of herbicide Bison Advance ensured the conservation of a significant part of the soybean crop. In Altai and Krasnodar regions, an additional 50.5-64.6% was obtained from the value of the untreated control, and in the Astrakhan region – 22.3-34.2%.
