Trunk injection of pesticides to combat Corythucha ciliata

Abstract

To scientific control forest alien invasive species，the control of Corythucha ciliata in the forest with five different pesticides：1）imidacloprid，2）emamectin benzoate，3）imidacloprid + abamectin，4）dichlorvos-omethoate were studied using trunk injection. Results showed that both 1）40.0 gL-1 imidacloprid + 1.5 gL-1 abamectin，which 5 d after a trunk injection with 0.10 Lm-1 controlled 95.33% and at 20 d 96.00%，and 2）300.0 gL-1（dichlorvos-omethoate），which at 5 d controlled at 97.31% and at 20 d 94.70%，had better control than the other supplied insecticides. This indicated that 40.0 gL-1 imidacloprid + 1.5 gL-1 abamectin and 300.0 gL-1（dichlorvos-omethoate） could be used to control C. ciliata.［Ch，1 tab. 4 ref.］
