摘  要:
[Objective] The aim was to determine and evaluate control effect and security of 20% tebufenozide SC against Spodoptera exigua Hübner,which will provide technical support for its promotion and utilization.[Method] By using foliar spray method,the control effects of different concentration 20% tebufenozide SC and 25 g/L deltamethrin EC against S.exigua were determined.[Result] 20% tebufenozide SC has better control effects on S.exigua.After spraying 3 d and 7 d,the control effects of 20% tebufenozide SC each treatment could reach 81% and 84%,which is higher than 25 g/L deltamethrin EC treatment.[Conclusion] 20% tebufenozide SC was good for controlling S.exigua,because of its favorable effect,continuing validity period more than 7 d,less pollution and safety.
