Abstract: To screen new pesticides with ideal sustained- release, long- lasting and low- toxic to control Ceratovacuna lanigera and Baliathrips serratus, and find out convenient and efficient pesticide application technology, 2% imidacloprid GR was selected and applied in soil for field efficacy trials. The results showed that 2% imidacloprid GR had good control effect on C. lanigera and B. serratus. It was a new pesticide with ideal sustained-release, long-lasting and low-toxin to control C. lanigera and B. serratus. Therefore, we could use it with other pesticides alternately to delay drug resistance. The optimum dosage of 2% imidacloprid GR was 30 kg/hm2 (with effective ingredients of 600 g). 2% imidacloprid GR (30 kg/hm2) mixed with regular fertilizer (40-80 kg/hm2) was applied one time at sugarcane planting or‘hilled up’soil between February and June. The control effect on C. lanigera and B. serratus could be more than 98.2% and 81.1%, respectively. The real yield and sucrose content increased by more than 33390 kg/hm2 and 6.6% compared with that of the control, respectively. The pesticide with sustained-release, long-lasting and strong systemic could be mixed with base fertilizer and top dressing and applied in the soil one time. This method is convenient, efficient, time saving and environment friendly, and should be applied widely in sugarcane planting area.
