Objective] The aim was to study control effect of 20% Nitenpyram AS against rice hopper. [Method] The control effect of 20% Nitenpyram AS a-gainst rice hopper was studied through plot experiment and demonstration area experiment. [Result] 20% Nitenpyram AS had obvious control effect against rice hopper and was safe to rice. And its had quicker control efficacy and longer control time. So it is suggested that 20%Nitenpyram AS could be used to control rice hopper at peak stage of young nymphs, the dose of 20%Nitenpyram AS was 375 ml/hm2. [Conclusion] The result provides reference for the control of rice hopper.
