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.
