摘 要：
2003~2004年,在山西太原进行了48%毒.辛乳油防治韭菜韭蛆田间药效试验。结果表明,在韭蛆发生期,用48%毒.辛乳油以1 440~2 160g.a.i./hm2剂量顺垄根部喷淋防治,药后3d的防治效果为85.3%~92.9%,药后7~14d的防治效果为83.1%~98.9%,等于或略好于对照农药48%乐斯本乳油1 440g.a.i./hm2,40%辛硫磷乳油3 000g.a.i./hm2和80%敌敌畏乳油2 400g.a.i./hm2处理的防效,持效期可达14d。

摘 要：
The experiment was carried out in 2003 and 2004 in Taiyuan of Shanxi Province for measuring effect of chlorpyrifos-phoxim 48% EC on control of Bradysia odoriphaga in field trials.The result showed that chlorpyrifos-phoxim 48% EC with dosages of 1 440～2 160g.a.i./hm~2 had a good effect to control Bradysia odoriphaga.The control effects were 85.3%～92.9% and 83.1%～98.9% in 3 day and in 7～14 days after treatment respectively,and the persistent effect reached 14 days.Its control effect was similar to or a little better than that by using 48% chlorpyrifos EC with 1 440g.a.i./hm~2 or 40% phoxim EC with 3 000g.a.i./hm~2 or 80% dichlorvos EC with 2 400g.a.i./hm~2.Therefor,chlorpyrifos-phoxim 48% EC was a potential candidate for Bradysia odoriphaga control.
