Abstract: 【Objective】 To determine the control efficacy of 60% Flumioxazin·Acetochlor·Clomazone oil dispersion on annual weeds in soybean fields.【Methods】 Field plot experiments were conducted in 2021 and 2022 to determine the plant number control efficacy and fresh weight control efficacy on annual weeds in soybean fields,as well as soybean yields following application of 60% Flumioxazin·Acetochlor·Clomazone oil dispersion.【Results】 At the application rate of 2 400-3 000 mL/hm2,the plant number control efficacy on total weeds was 84.5%-97.4% in 2021 and 86.7%-97.9% in 2022,respectively,and the fresh weight control efficacy was 90.1%-99.0% in 2021 and 91.1%-99.2% in 2022,respectively at 40 d after application;compared to the control,the soybean yield in all tested herbicide treatment plots increased significantly in both 2021 and 2022,with yield increase rates of 115.8%-142.7% and 96.2%-108.6%,respectively.【Conclusion】 The 60% Flumioxazin·Acetochlor·Clomazone oil dispersion,when applied at a dosage of 3 000 mL/hm2,exhibits excellent control efficacy on annual weeds in soybean fields.
