| Abstract: | In the field experiment,the effects of 2% avermectin EC on controlling rice gall midge were studied.Different dosages of 2% avermectin EC including 75 g ai/hm2,150 g ai/hm2 and 225 g ai/hm2 were applied on rice,and the control effect was 93.69%,96.59% and 98.59%,respectively, in 20 days after application,which was the same as that of the CK,1650g ai/hm2 10% ethoprobos FG.So,2% avermectin EC with 150-200 g ai/hm2 could be used for rotating 10% ethoprobos FG to control rice gall midge in production. |
