| 摘 要： | 4种杀虫剂对稻纵卷叶螟的田间药效试验表明:20%氯虫苯甲酰胺SC、15%茚虫威SC和31%三拂ME对低龄稻纵卷叶螟幼虫均具有优良的防治效果,其防效均在90.08%以上;而对于高龄稻纵卷叶螟幼虫,20%氯虫苯甲酰胺SC 30、45 g/hm2(有效成分)的防效在89.12%以上,其他3种药剂处理的防效均较差。

| Abstract: | The field trail in the control efficiency of 4 insecticides against rice leaffolder,Cnaphalocrocis medinalh(Guenée) have been done.The experimental results showed that 20% chlorantraniliprole SC,15% indoxacarb SC and 31% sanfu(fipronil + triazophos) ME gave excellent control efficiency(over 90.08%) against the 1st~2nd instar larvae;while against the 3rd instar larvae,20% chlorantraniliprole SC at concentrations of 30g a.i./hm2 and 45g a.i./hm2 provided the control efficiency of more than 89.12%,the other insecticides had lower control efficiency. |
