摘　　要：[目的]为了考察多杀霉素与甲维盐混配对防治二化螟是否有增效作用。田间采用茎叶喷雾方式,测试10%多杀霉素.甲维盐水分散粒剂对水稻二化螟的防治效果。[结果]单独使用5%多杀霉素水分散粒剂和5%甲维盐水分散粒剂对水稻的保苗效果和杀虫效果均较低,而10%多杀霉素.甲维盐水分散粒剂随着其用量的增加对水稻的保苗效果和杀虫效果增加,与2个单剂的作用效果存在显著差异。[结论]多杀霉素和甲维盐混配有明显的增效作用。[Aims] The objective of this study was to investigate the synergic effect of the mixture of spinosad and emamectin on the rice stem borer. The control effect was evaluated by spraying of spinosad, emamectin benzoate 10% WG to the stems of rice plants in field. [Results] The higher the dose, the greater the protecting seedling and insecticidal effects on rice of spinosad · emamectin benzoate 10% WG, while the effects of spinosad 5% WG and emamectin 5% WG used separately were both significantly lower than those of the mixture. [Conclusions] The synergic effect of the mixture of spinosad and emamectin on the rice stem borer were obviously.
