摘要：

近年来，二化螟在宁波市水稻上逐年加重发生。为明确纳米水性制剂（以下简称“纳米农药”）对二化螟的防治效果，在二化螟防治适期，选择甲氨基阿维菌素苯甲酸盐传统制剂和纳米制剂、乙多·甲氧虫、乙基多杀菌素、四唑虫酰胺共5种杀虫剂开展田间药效试验。结果表明，5%甲氨基阿维菌素苯甲酸盐纳米制剂施药14 d后的枯心防效和杀虫防效分别在80%和85%以上，且保产效果更佳，挽回损失率达44%~45%，防效及挽回损失率均极显著高于5%甲氨基阿维菌素苯甲酸盐传统制剂。

Abstract:

In recent years, the occurrence of Chilo suppressalis in rice production in Ningbo has been increasing year by year. In order to clarify the control effects of nanopesticides on Chilo suppressalis, a field efficacy trial was conducted during the appropriate period for controlling Chilo suppressalis, the traditional formulation and the nano-preparation of Emamectin Benzoate, Spinetoram and Methoxyfenozide, Spinetoram and Tetraniliprole were selected as experimental reagents. The results showed that after 14 days of pesticide application, the dry heart and insecticide control effect of Emamectin Benzoate (nano-preparation) were above 80% and 85%, respectively, and the yield retention effect was better, with a recovery loss rate of 44% to 45%. The pest control effects and recovery loss rate of nanopesticides were significantly higher than those of traditional formulations.

Key words: rice, Chilo suppressalis, nanopesticide, control effects
