This drug is an effective herbicide for the control of annual and perennial grasses and dicotyledons in corn crops, is rapidly absorbed through the leaves and partially through the root system, and acts throughout the plant in parallel with the decrease and increase in nutrient flows. The substances contained in the drug accumulate in the growth points, including in the buds. The growth of weeds stops immediately after application of the herbicide (1-2 hours). After 4-10 days, the leaves turn yellow, red spots appear, which gradually turn into black spots, and complete drying and death of weeds is observed within 15-20 days. The speed of the herbicide action depends on the type of weeds and air temperature conditions.
