40 g/L喹禾糠酯乳油对大豆田一年生禾本科杂草的防效

Control Effect of 40 g/L Quizalofop-P-tefuryl on Annual Grass Weeds in Soybean Field

研究了40 g/L喹禾糠酯乳油对大豆田禾本科杂草的防除效果。结果表明,40 g/L喹禾糠酯乳油对大豆田禾本科杂草防除效果较好,中高剂量处理下,对杂草的鲜重防效最高可达99.10%,持效期可达30 d左右,且对大豆安全。该试验结果能够为大豆田禾本科杂草的合理防除提供理论依据。

In this experiment,the control effect of 40 g/L Quizalofop-P-tefuryl on 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.
