| 中文摘要: |
| 本研究采用室内毒力测定, 助剂润湿铺展性能和田间防治效果评价研究了自研“PDMS”系列助剂（PDMS-01、PDMS-02、PDMS-03、PDMS-04）对10%甲维盐·氯虫苯甲酰胺悬浮剂防治草地贪夜蛾的增效作用。结果表明, PDMS系列助剂均可提高10%甲维盐·氯虫苯甲酰胺悬浮剂的毒力;7.5~17.5 g/L处理药液中添加助剂PDMS-01, 药液润湿时间降低172.84～176.59 s, 药液表面张力降低15.26~16.28 mN/m, 玉米叶片正、背面静态接触角分别降低13.39°~24.12°和12.02°~27.56°;10%甲维盐·氯虫苯甲酰胺悬浮剂减量30%（21 g/667m 2）并添加PDMS-01后, 无人机施药对草地贪夜蛾的3 d和14 d田间防效分别可达76.62%和82.36%, 与未减量处理（30 g/667m 2）的防效差异不显著, 与添加KQ-103、凯耀高航处理差异也不显著。助剂PDMS-01可显著改善10%甲维盐·氯虫苯甲酰胺悬浮剂药液的润湿铺展性能, 减少药剂用量30%对草地贪夜蛾仍有较高防效, 且速效性和持效性较好。 |
| 英文摘要: |
| The synergism of self-developed “PDMS” adjuvants (PDMS-01, PDMS-02, PDMS-03, PDMS-04) on emamectin benzoate·chlorantraniliprole (EBC) 10% SC against Spodoptera frugiperda were investigated in this study. The results showed that all the four PDMS adjuvants could increase the toxicity of EBC 10% SC. When PDMS-01 was added into the 7.5-17.5 g/L EBC 10% SC, the wetting time of the liquid was reduced by 172.84-176.59 s, the surface tension of the liquid was reduced by 15.26-16.28 mN/m, and the static contact angle of the front and back surface on corn leaves was reduced by 13.39°-24.12° and 12.02°-27.56°, respectively. The field control effect of the EBC 10% SC at the dosage of 21 g/667m 2 (30% reduction) against S.frugiperda could reached 76.62% and 82.36% 3 d and 14 d, respectively, after mixed with PDMS-01, which show no significant difference from that of the routine dosage (30 g/667m 2) and the treatments mixed with commercial adjuvant (KQ-103 and Kaiyaogaohang). The addition of PDMS-01 can significantly improve the wetting and spreading performance of EBC 10% SC and enhance its quick-acting and persistent effect on S.frugiperda under the condition of 30% reduction. |
