Abstract
The synergism of Rotenone and Imidacloprid against Uroleucon gobonis was determined with leaf-immersing method,and their optimal ratio was confirmed.The result showed that the mixture of Rotenone and Imidacloprid had synergic action certainly.When the ratio was about 3.55∶1,the CTC was the highest(138.0333).The field trial showed that the effect of 1000~2000 times mixture EC of Rotenone and Imidacloprid(3.6∶1) on Uroleucon gobonis was obvious after application.
