Influence of the application of herbicides step 500 and ankosar on annual and perennial weeds in fine-fiber cotton crops

AbstractIn this scientific article, materials on the effectiveness of the use of a combination of herbicides with a different spectrum of action against annual and perennial weeds in fine-fiber cotton crops sown on ridges and a smooth field in meadow soils are provides. Sowing cotton seeds along the ridges and using a combination of herbicides Step 500, 50% ae. when sowing at a rate of 4.0 l/ha and Ankosar 720 g/l c. R. at a rate of 4.0 l/ha before cotton budding, or at a weed height of 10–15 cm, reduces the number of annual weeds by 92.2–95.6%, perennial weeds by 91.6–92.4%, cotton yield increases by 5.0 centners/ha.
