The prevention and control efficacy appear two peak,respectively after application ld and 3d,insecticidal rate is 3-5d. The 5 kg/hm2 of Sendebon finished powder is the best dose on prevention and control before the 3 instar larvae of Dictyoploca japonica Butler,after application 4D control effect reaches 94.3 %;the forest application demonstration test indicates:the 5 kg/hm2 of Sendebon finished powder is the best dose,control effect 91.4%,all the leaves have not reached the standard of disaster,prevention and control direct cost for 55.5¥/hm2. The drug is safe for human and animals, no pollution, no harm, knockdown force strong, fast insecticidal speed,on Di- ctyoploca japonica Butler larvae have a very good killing effect,is the present high toxic pesti- cides new preferred alternative products, can popularization and application in large area produc- tion.
