摘　　要：为明确早稻上常用药剂对二化螟的防治效果及对稻纵卷叶螟的影响,2023年5—8月开展了田间药剂试验。结果表明,667 m^(2)使用25%喹硫磷乳油100 mL、25%乙基多杀菌素水分散粒剂12 g和新型药剂CS003-S 30 mL对二化螟具有较好的防治效果,防治效果均在85%以上,产量挽回损失率超35%。而667 m^(2)使用34%乙多·甲氧虫悬浮剂24 mL、200 g·L^(-1)四唑虫酰胺悬浮剂10 mL在二化螟上防治效果较差,不建议单独使用。在早稻上施用这些药剂后会不同程度加重后期稻纵卷叶螟的发生,其中667 m^(2)使用25%喹硫磷乳油100 mL或新药剂CS003-S 30 mL后,卷叶数显著多于空白对照,可能是田间天敌数量受药剂影响所致。因此,从经济效益和生态效益出发,在早稻上施用25%乙基多杀菌素水分散粒剂较为合适。In order to clarify the control effect of commonly used pesticides on Chilo suppressalis Walker and the effect on leaf roller borer in early rice,field pesticide trials were carried out from May to August 2023.The results showed that 667 m^(2) with 100 mL of 25%quinthion EC,12 g of 25%ethylspinosasad water-dispersible granules and 30 mL of new agent CS003-S had good control effect on Chilo suppressalis Walker,and the control effect was more than 85%,and the yield recovery loss rate was more than 35%.In 667 m^(2),24 mL of 34%ethyl methoxy insect suspension,and 10 mL of 200 g·L^(-1) tetrazolium anthramide suspension had poor control effect on Chilo suppressalis Walker,and they were not recommended to use alone.The application of these pesticides on early rice would aggravate the occurrence of leaf roller borer in the later stage to varying degrees,and the number of leaf curls after 667 m^(2) using 100 mL of 25%quinthion EC or 30 mL of the new agent CS003-S were significantly higher than that of control,which may be caused by the influence of pesticides on the number of natural enemies in the field.Therefore,from the perspective of economic and ecological benefits,it is more appropriate to apply 25%ethylspinosasad water-dispersible granules on early rice.
