Some herbicides and their mixtures were tested for their effects on kochia (Kochia scoparia). Herbicides were applied to kochia plants at different developmental stages. Herbicide efficacy was expressed as percent of killed plants. Applications to plants grown from seeds under defined conditions resulted in 100 % efficacy of herbicide Arsenal (250 g of the active ingredient imazapyr) at a dose of 4 l/ha within 40 days from treatment. Herbicide Grodyl 75 WG (75 g of amidosulfuron as a. i.) gave 18 % efficacy at a dose of 80 g/ha within 40 days.
