The aftereffect of Lumax herbicide applied to corn crop on weed vegetation and yields of soybean, wheat and buckwheat was studied. The studies were carried out in 2021 and 2022 in the Primorsky Territory. The soil of the experimental plots was meadow–brown podzolized, containing 3–4% of hu mus in the plough-layer. The herbicide was applied before sprouting and in the 2–3 leaf phase in corn in 2020 and 2021 at the recommended (4.0 l/ha) and twice (8.0 l/ha) the recommended application rates. Growing seasons 2021 and 2022 were characterized by uneven precipitation. Daytime tempera tures on most days in July and early August reached 28–36 ºC. When sowing wheat and soybean in the experimental plot on the variants with Lumax herbicide application, annual weed plants germinated less than in the control. This was the result of the high efficacy of the drug in the year of application, which reduced seed inputs to the soil. Lumax herbicide inhibited the growth and development of wormwood, the number of which was 53–81% lower than in the herbicide-free variant. The residual phytotoxic effect of Lumax herbicide on wheat and buckwheat yields was revealed. Regardless of the timing of its application and rates of consumption, the yield of buckwheat green mass was lower than in the control by 15–27 c/ha. 14.8 c/ha of wheat grain was harvested on the variant of pre-emergence application of Lumax at twice the recommended rate of consumption, while the yield in the control was 16.6 c/ha.
