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.

Key words Soybean field;Quizalofop-P-tefuryl;Control effect
