How can weeds be effectively controlled during soybean cultivation?
How do you control weeds when growing soybeans? The main weeds in soybean cultivation include monocotyledonous weeds such as crabgrass, barnyardgrass, goosegrass, lambsquarters, and foxtail; broadleaf weeds include redroot pigweed, eclipta, copperleaf, and velvetleaf. Summer soybeans are usually sown in June, during the hot and rainy season, when weeds emerge aggressively, at high density, grow vigorously, and are diverse in species, easily forming a weed infestation. Generally, weeds begin to emerge 5 days after soybean sowing, and the entire weed emergence period lasts about 60 days, which is extremely unfavorable for high soybean yields. For this reason, accurately mastering chemical weed control techniques is crucial.
