摘　要：为了筛选出防治水稻二化螟和稻纵卷叶螟的有效农药，参照农药田间药效试验准则，开展了氯虫苯甲酰胺及其五种复配制剂的田间药效试验。结果显示，30%氯虫苯甲酰胺悬浮剂（施药量75 g a.i./hm2）和19.4%甲维·氯虫苯甲酰胺可分散油悬浮剂（施药量75 g a.i./hm2）对二化螟的虫口防效和保穗防效均超过90%，60%氯虫苯甲酰胺·吡蚜酮水分散粒剂（施药量150 g a.i./hm2）和50%氯虫苯甲酰胺·呋虫胺水分散粒剂（施药量75 g a.i./hm2）的防效均超过80%；30%氯虫苯甲酰胺悬浮剂（施药量75 g a.i./hm2）、40%氯虫苯甲酰胺·噻虫胺悬浮剂（施药量150 g a.i./hm2）和19.4%甲维·氯虫苯甲酰胺可分散油悬浮剂（施药量75 g a.i./hm2）对稻纵卷叶螟的保叶防效和虫口防效均在90%左右，60%氯虫苯甲酰胺·吡蚜酮水分散粒剂（施药量150 g a.i./hm2）的防效均在85%左右。在二化螟和稻纵卷叶螟的田间防治中，优先推荐使用19.4%甲维·氯虫苯甲酰胺可分散油悬浮剂，其次使用60%氯虫苯甲酰胺·吡蚜酮水分散粒剂，防治二化螟时也可使用50%氯虫苯甲酰胺·呋虫胺水分散粒剂，防治稻纵卷叶螟时也可使用40%氯虫苯甲酰胺·噻虫胺悬浮剂。

Abstract：For screening effective insecticides for controlling Chilo suppressalis and Cnaphalocrocis medinalis, field efficacy trials of chlorantraniliprole and its 5 compound formulations were conducted with reference to the guidelines for field efficacy trials of pesticides. The field efficacy test results showed that 30% chlorantraniliprole SC (application amount 75 g a.i./hm2) and 19.4% emamectin benzoate·chlorantraniliprole OD (application amount 75 g a.i./hm2) had the best ear protection effect and insect control effects against Chilo suppressalis, both exceeding 90%, 60% chlorantraniliprole·pymetrozine WG (application amount 150 g a.i./hm2) and 50% chlorantraniliprole·dinotefuran WG (application amount 75 g a.i./hm2) had better control effects, both exceeding 80%; 30% chlorantraniliprole SC (application amount 75 g a.i./hm2), 40% chlorantraniliprole·clothianidin SC (application amount 150 g a.i./hm2), and 19.4% emamectin benzoate·chlorantraniliprole OD (application amount 75 g a.i./hm2) had the best control effects against Cnaphalocrocis medinalis, all about 90%, the control effect of 60% chlorantraniliprole·pymetrozine WG (application amount 150 g a.i./hm2) was better, both about 85%. In the field control of Chilo suppressalis and Cnaphalocrocis medinalis, 19.4% emamectin benzoate·chlorantraniliprole OD was preferred, followed by 60% chlorantraniliprole·pymetrozine WG, if only used for field control Chilo suppressalis, 50% chlorantraniliprole·dinotefuran WG could also be used, if only used for field control Cnaphalocrocis medinalis, 40% chlorantraniliprole·clothianidin SC could also be used.
