摘　　要：为探究氟苯虫酰胺单剂和混剂对草地贪夜蛾的防治效果、最佳使用剂量及对玉米的安全性,试验选用20%氟苯虫酰胺悬浮剂制剂量300、225、150mL/hm^(2)3种剂量处理,12%氟苯虫酰胺·甲维盐微乳剂375、300、225 mL/hm^(2)3种剂量处理,5%甲维盐水分散粒剂300 g/hm^(2)进行田间试验。结果表明,3种农药在不同剂量下对草地贪夜蛾均有防治效果,其中防治效果最好的是12%氟苯虫酰胺·甲维盐微乳剂,在375和300 mL/hm^(2)2个剂量下均体现了很好的速效性和持效性;其次是20%氟苯虫酰胺悬浮剂,在300 mL/hm^(2)时防效最优,速效性和持效性较好;5%甲维盐水分散粒剂对草地贪夜蛾有较好的速效性,但持效性不理想。In order to assess the control effect,optimal application rate and safety to corn of flubendiamide-based products containing a single-active ingredient and mixed formulation products containing active ingredient beyond flubendiamide,field tests were conducted selecting three treatments of 20%flubendiamide SC at rates of 300 mL/hm^(2),225 mL/hm^(2)and 150 mL/hm^(2)three dosage,12%flubendiamide·emamectin benzoate ME at rates of 375 mL/hm^(2),300 mL/hm^(2)and 225 mL/hm^(2)three dosage treatments,and 5%emamectin benzoate WG at a rate of 300 g/hm^(2).The results showed that all the three pesticides had varying degrees of control effects against Spodoptera frugiperda at different doses.The best control effect was observed with 12%flubendiamide·emamectin benzoate ME,particularly at dose of 375 mL/hm^(2)and 300 mL/hm^(2),demonstrating both rapid action and persistence.The second most effective was 20%flubendiamide SC,with best Pesticide Science and Administration 2024,45(5)control effect at a dose of 300 mL/hm^(2),displaying quicker action and better persistence.Although 5%emamectin benzoate WG had rapid action against Spodoptera frugiperda,its persistence was not ideal.
