Control Effects of Six Pesticides Such as Beta-Cypermethrin·Thiamethoxam on Citrus Psyllid

[Aims] The aims were to screen out the pesticides with high efficiency and low toxicity against citrus psyllid,and to provide scientific reference for the application of pesticides. [Methods] The control effects in field trial of six pesticides such as beta-cypermethrin·thiamethoxam on citrus psyllid were studied according to guidelines on efficacy evaluation of pesticides. [Results] The control effects of beta-cypermethrin·thiamethoxam 22% MS-SC 73.3 mg/kg,imidacloprid 10% WP 66.7 mg/kg and cypermethrin 4.5% EC 45 mg/kg against citrus psyllid at 15 days were 93.95,91.14 and 89.32%, respectively. [Conclusions] The control effects of these pesticides against citrus psyllid were excellent, which were worthy to be popularized in production.
