用90%万灵可溶性粉与克幼脲超微粉混合制成的复配剂(55g/667m2),防治棉铃虫的效果与44%多虫清(60ml/667m2)相当,比辛硫磷(100ml/667m2)处理效果高出30%;可维持60%以上的防效7d以上;取食喷洒过复配剂药液棉叶的3、4龄棉铃虫幼虫,基本不能化蛹或羽化;示范应用复配剂防治棉铃虫1次,相当于常规治虫3次的效果;试验示范结果均表明,该复配剂是有效控制棉铃虫的药种之一。
The effect of preventing and controlling cotton bollworm was the same as that of 44% multifungus (60ml / 667m2) with the compounding agent (55g / 667m2) mixed with 90% / 667m2), the treatment effect is higher than 30%; the anti-efficiency of more than 60% can be maintained for more than 7d; the third and fourth instar larvae of cotton bollworm sprayed with the compound drug solution cotton leaf can not basically pupate or emerge; The compounding agent was used to control the bollworm once, equivalent to the effect of conventional pest control three times. The experimental demonstration results show that the compounding agent is one of the effective drugs for controlling the bollworm.
