| 摘 要： | 采用叶片浸渍法测定了印楝素与鱼藤酮混配对牛蒡长管蚜的增效作用及两种药剂混配的最佳配比。结果表明,当二种药荆之比位于12.60:1和1.03:1之间时,混配制剂表现较明显的增效作用;当2种药剂之比为4.4:1时,增效作用最强,此时的共毒系数为348.1075。田间试验结果表明,印楝素与鱼藤酮按有效成分4.4:1比例进行混配后的1000、1500倍液对牛蒡长管蚜有较好的防治效果。

| Abstract: | The synergism of Azadirachtin and Rotenone against Uroleucon gobonis with immerse leafs method,and their best ratio were studied.The result showed that the mixture of Azadirachtin and Rotenone had significant synergic action,when the ratio was between 12.60:1 and 1.03:1.The CTC was the highest (348.1075),when the ratio was 4.4:1.In the field trial,the control effect of 1 000 and 1500 times with 4.4:1 mixture EC to Uroleucon gobords was good after application. |
