| 摘 要：為了篩選出防治水稻二化螟和稻縱卷葉螟的有效農藥，參照農藥田間藥效試驗準則，開(kāi)展了氯蟲(chóng)苯甲酰胺及其五種復配制劑的田間藥效試驗。結果顯示，30%氯蟲(chóng)苯甲酰胺懸浮劑（施藥量75 g a.i./hm2）和19.4%甲維·氯蟲(chóng)苯甲酰胺可分散油懸浮劑（施藥量75 g a.i./hm2）對二化螟的蟲(chóng)口防效和保穗防效均超過(guò)90%，60%氯蟲(chóng)苯甲酰胺·吡蚜酮水分散粒劑（施藥量150 g a.i./hm2）和50%氯蟲(chóng)苯甲酰胺·呋蟲(chóng)胺水分散粒劑（施藥量75 g a.i./hm2）的防效均超過(guò)80%；30%氯蟲(chóng)苯甲酰胺懸浮劑（施藥量75 g a.i./hm2）、40%氯蟲(chóng)苯甲酰胺·噻蟲(chóng)胺懸浮劑（施藥量150 g a.i./hm2）和19.4%甲維·氯蟲(chóng)苯甲酰胺可分散油懸浮劑（施藥量75 g a.i./hm2）對稻縱卷葉螟的保葉防效和蟲(chóng)口防效均在90%左右，60%氯蟲(chóng)苯甲酰胺·吡蚜酮水分散粒劑（施藥量150 g a.i./hm2）的防效均在85%左右。在二化螟和稻縱卷葉螟的田間防治中，優(yōu)先推薦使用19.4%甲維·氯蟲(chóng)苯甲酰胺可分散油懸浮劑，其次使用60%氯蟲(chóng)苯甲酰胺·吡蚜酮水分散粒劑，防治二化螟時(shí)也可使用50%氯蟲(chóng)苯甲酰胺·呋蟲(chóng)胺水分散粒劑，防治稻縱卷葉螟時(shí)也可使用40%氯蟲(chóng)苯甲酰胺·噻蟲(chóng)胺懸浮劑。 |

| 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. |
