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。
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.
