We conducted the research in 2018-2020 to identify the effective herbicide tank mixtures on oil flax, under conditions of unstable and insufficient moistening zones in the south of Russia, and to determine their impact on productivity and economic efficiency of crop cultivation. The object of research was oil flax varieties of the breeding of V.S. Pustovoit All-Russian Research Institute of Oil Crops, in the zone of unstable moistening on leached chernozem (Russia, Krasnodar) – FLIZ and Nilin, in the zone of insufficient moistening on typical chernozem (Russia, Rostov region) – Raduga. The average yield in the zone of unstable moistening of varieties FLIZ and Nilin was 1.25 t/ha and 0.93 t/ha, respectively, the average yield in the zone of insufficient moistening of variety Raduga was 1.19 t/ha. The application of tank mixtures Sekator Turbo, OD (0.1 l/ha) + Zellek-super, EC (1.0 l/ha) and Sekator Turbo, OD (0.1 l/ha) + Zellek-super, EC (1.0 l/ha) + Albit, RP (0.1 l/ha) decreases crop productivity by 4-8% of the control without treatment. The best economic efficiency in the zone of unstable moistening had the variant Sekator Turbo, OD (0.1 l/ha) + Bagheera, EC (1.5 l/ha), in the zone of insufficient moistening – Sekator Turbo, OD (0.1 l/ha) + Miura, EC (1.2 l/ha). Significant yield increases were obtained in the variety FLIZ – 0.11 t/ha, and 0.03, 0.02, or contributed to the fields clean from weeds. When tank mixtures Sekator Turbo, OD (0.1 l/ha) + Bagheera, EC (1.5 l/ha) and Sekator Turbo, OD (0.1 l/ha) + Miura, EC (1.2 l/ha) were used, the flax sowings were weed-free, which contributed to keeping the crop yield or its increase.
