摘要
选用毒死蜱、氯虫苯甲酰胺、阿维菌素和甲维盐4种化学药剂的单剂及其混配组合,在室内对二化螟进行了毒力测定,筛选出最佳混配比例(有效成分):毒死蜱与甲维盐(1∶1)、毒死蜱与氯虫苯甲酰胺(10∶1)、阿维菌素与氯虫苯甲酰胺(1∶1)、阿维菌素与毒死蜱(1∶1),其共毒系数分别为376.77、254.84、247.10和682.34。田间试验结果表明,室内所获得的混配组合对二化螟的防治效果均达到76.4%以上,可有效防治二化螟,且对水稻生长安全。
The joint action of the mixtures of chlorpyrifos,emamectin benzoate,chlorantraniliprole and abamectin were studied on Chilo suppressalis Warker.The results showed that when the ratio of chlorpyrifos to emamectin benzoate was 1∶1,chlorpyrifos to chlorantraniliprole was 10∶1,abamectin to chlorantraniliprole was 1∶1 and abamectin to chlorpyrifos was 1∶1,the co-toxicity coefficient（CTC） of the mixtures were the maximum.The CTC were 376.77,254.84,247.10 and 682.34 respectively.The field trials showed that these mixtures could control C.suppressalis effectively,the control effect were all above 76.4%,and the mixtures were safety to the rice.
