为明确溴虫氟苯双酰胺悬浮剂对食用型向日葵（食葵）棉铃虫和蓟马的田间防治效果，以食葵品种双星60为试验对象，设6个处理，分别为100 g/L溴虫氟苯双酰胺悬浮剂150 mL/hm²（处理1）、225 mL/hm²（处理2）、300 mL/hm²（处理3），10%溴氰虫酰胺可分散油悬乳剂300 mL/hm²+100 g/L微量元素水溶肥375 mL/hm²（处理4），60 g/L乙基多杀菌素悬浮剂300 mL/hm²+10%高效氯氰菊酯悬浮剂300 mL/hm²（处理5）和清水对照（CK）。采用随机区组设计，3次重复，于药后1、3、7 d调查虫口数，评估各处理对食葵生长的安全性，并测定其对食葵主要害虫棉铃虫和蓟马的防治效果。结果表明，药后7 d，处理2、3对棉铃虫的防治效果分别为89.84%、93.61%，对蓟马的防治效果分别为79.68%、85.17%，2个处理间差异均无统计学意义（P>0.05）；处理2、3对棉铃虫的防治与当前常用药剂组合处理4、5的差异无统计学意义（P>0.05）；试验所用药剂均对食葵生长安全。综合表明，100 g/L溴虫氟苯双酰胺悬浮剂对棉铃虫、蓟马具有较好的防治效果，且随施用量的增加，其防治效果也增加，在食葵大田生产中，可选择在常规情况下施用100 g/L溴虫氟苯双酰胺悬浮剂225 mL/hm²（处理2），在棉铃虫、蓟马发生量较大或棉铃虫幼虫虫龄偏大时施用100 g/L溴虫氟苯双酰胺悬浮剂300 mL/hm²（处理3）。

To clarify the field control efficacy and application rate of broflanilide against Helicoverpa armigera and thrips on edible sunflower, the experiment was conducted using the edible sunflower variety Shuangxing 60 as the test material, with 6 treatments set as followed treatment 1, 100 g/L broflanilide suspension concentrate at 150 mL/hm²; treatment 2, 100 g/L broflanilide suspension concentrate at 225 mL/hm²; treatment 3, 100 g/L broflanilide suspension concentrate at 300 mL/hm²; treatment 4, 10% cyantraniliprole oil dispersion at 300 mL/hm²+100 g/L trace element water-soluble fertilizer at 375 mL/hm²; treatment 5, 60 g/L spinetoram suspension concentrate at 300 mL/hm²+10% beta-cypermethrin suspension concentrate at 300 mL/hm²; and clear water control (CK). A randomized complete block design was adopted with 3 replications. The population density of pests was investigated at 1, 3, and 7 days after application to evaluate the safety of each treatment on the growth of edible sunflower, and to determine its control efficacy against the main pests of oil sunflower, namely Helicoverpa armigera and thrips. The results showed that 7 days after application, the control efficiencies of treatments 2 and 3 against Helicoverpa armigera were 89.84% and 93.61%, respectively, and those against thrips were 79.68% and 85.17%, respectively. There were no statistically significant differences between the 2 treatments (P>0.05). Additionally, no statistically significant differences were observed in the control efficiency against Helicoverpa armigera between treatments 2, 3 and the currently commonly used pesticide combination treatments 4, 5 (P>0.05). All pesticides tested were safe for the growth of oil sunflower. In conclusion, the results indicate that the 100 g/L bromofluazuron suspension concentrate exhibits good control effects against Helicoverpa armigera and thrips, and the control effect increases with the increase in application rate. In the field production of oil sunflower, the 100 g/L bromofluazuron suspension concentrate can be applied at a rate of 225 mL/hm² (treatment 2) under normal conditions, and at 300 mL/hm² (treatment 3) when the population density of Helicoverpa armigera and thrips is high or the larval instars of Helicoverpa armigera are older.
