Abstract In this experiment， the control effect of 40 g/L Quizalofop-P-tefurylon grass weeds in soybean field was studied.The results showed that 40 g/L Quizalofop-P-tefuryl had a good control effect on grass weeds in soybean field. Under medium and high dose treatment， the control effect on fresh weight of weeds was up to 99.10%， and the lasting time was about 30 days， and it was safe for soybean.The results can provide theoretical basis for rational control of grass weeds in soybean fields.
