In 2020-2021, we conducted research on the effect of herbicides on oil flax productivity and volunteer plants of imidazolinone-resistant sunflower in oil flax sowings. We used the contact herbicide Basagran, AS (a.i. bentazon, 480 g/l) and the systemic herbicides Tifi, WDG (a.i. thifensulfuron-methyl, 750 g/kg), Cleo, WDG (a.i. clopyralid, 750 g/kg), Magnum, WDG (a.i. metsulfuron-methyl, 600 g/kg), Zellek-super, EC (a.i. haloxyfop-P-methyl,104 g/l), Miura, EC (a.i. quizalofop-P-ethyl,125 g/l), Sekator Turbo, OD (a.i. amidosulfuron, 100 g/l + iodosulfuron-methyl-sodium, 25 g/l + mefenpyr-diethyl, 250 g/l). We evaluated the phytotoxicity of the herbicides on the volunteer plants using a 9-point EWRC scale. We found that the of Basagran, AS (4.0 l/ha) + Zellek-super, EC (1.0 l/ha) + Cleo, WDG (0.12 kg/ha) provides the effective control of the volunteer plants and contributes to the stable high indicators of oil flax productivity. |
