Effectiveness of herbicide tank mixtures with Sekator turbo and graminicdes for oil flax

The purpose of the study is a comparative assessment of the effectiveness of tank mixtures of post-emergence herbicides on oil flax aimed at suppressing vegetative dicotyledonous and monocotyledonous weeds in crops. Objectives: to study the herbicidal compositions of tank mixtures based on several combinations of effective drugs against weeds, non-phytotoxic and capable of increasing the production of high-quality oil flax. The object of the study is tank mixtures of graminicides with herbicide Sekator Turbo - 0.1 l/ha. The experimental scheme included six options: control, without treatment (variant 1); tank mix options: Sekator Turbo OD (0.1 l/ha) + Bagheera, EC (1.5 l/ha) (variant 2); Sekator Turbo, OD (0.1 l/ha) + Fuzilade Forte, EC (1.0 l/ha) (variant 3); Sekator Turbo, OD (0.1 l/ha) + Quickstep, FEM (0.8 l/ha) (variant 4); Sekator Turbo, OD (0.1 l/ha) + Miura, EC (1.2 l/ha) (variant 5); Sekator Turbo, OD (0.1 l/ha) + Zellek-super, EC (1.0 l/ha) (variant 6). It was revealed that the use of tank mixes (options 3, 4 and 5) provided a net income from the sale of oilseeds in the amount of 16,463-17,491 r/ha with a profitability of 78-82 %. Option 6 is not economically feasible due to the low level of crop yield and the high cost of the herbicidal composition. The use of tank mix in option 2 provided the best indicators of economic efficiency in the cultivation of oil flax due to the highest yield (1.34 t/ha) and net income (19115 r/ha). Based on the conducted studies, the herbicide Bagheera EC, is recommended for inclusion in the "State Catalog of Pesticides and Agrochemicals" for its use on oil flax.
