摘　　要：[目的]评价吡虫啉种衣剂及其与氟虫双酰胺混用对水稻灰飞虱及黑条矮缩病等病毒病的控制效果.[方法]通过田间小区试验研究了吡虫啉种衣剂及其与氟虫双酰胺混用控制水稻灰飞虱及黑条矮缩病等病毒病的效果.[结果]吡虫啉600 FS 83.3 ～125.0ml/hm2及其与氟虫双酰胺混用400 FS150.0 ～ 300.0 ml/hm2在灰飞虱和黑条矮缩病重发生情况下,秧田虫口防效高达45％ ～55％,大田病害防效在28.71％ ～ 56.52％,结合无纺布覆盖育苗以及秧田期防治灰飞虱,可有效控制病毒病的发生.[结论]为吡虫啉种衣剂的应用及水稻病毒病的防治提供了理论依据.[ Objective ] The aim was to evaluate efficacy of Imidacloprid FS and its mixer with Flubendiamide FS on L. striateUus and RBSDV.[ Method] The effects of Imidacloprid FS and its mixer with Flubendiamide FS on L. striateUus and RBSDV were studied through field plot experi-ment. [ Result] After Imidacloprid 600 FS at 83.3 - 125.0 ml/hm2 and its mixer with Flubendiamide 400 FS at 150.0 - 300.0 ml/hm2 were usedto control L. striatellus and RBSDV, the efficiency of seedling bed reached 45.00% - 55.00%, and the efficiency of rice field diseases reached28.71%-56.52%. Combining with non-woven fabric covering seedling as well as controlling L. striateUus at seedling stage, rice stripe diseasecould be controlled effectively. [ Conclusion] The results provide theoretical basis for the application of Imidacloprid FS and the control of rice vi-rus diseases.
