| 【目的】探究有机硅、混合橙精油、青皮桔油、激健 4 种助剂对啶虫脒防治烟粉虱的增效作用及
有机硅 3 000 倍液对啶虫脒防治烟粉虱的减量效果。【方法】试验采用喷雾法，有机硅 3 000 倍液、混合橙精油
1 000 倍液、青皮桔油 1 000 倍液、激健 3 000 倍液分别与 5% 啶虫脒乳油推荐用量混用，测定药液的雾滴密度、
雾滴覆盖率对烟粉虱防效及有机硅 3 000 倍液对啶虫脒防治烟粉虱的减量效果。【结果】在 5% 啶虫脒乳油推荐
用量药液中添加助剂可提高药液的雾滴密度，但不同助剂与 5% 啶虫脒乳油推荐用量混用对烟粉虱的防效不同，
其中有机硅对啶虫脒防治烟粉虱的增效明显，持效期长，青皮桔油次之，而混合橙精油与啶虫脒的混合液对烟
粉虱的防效与清水对照无显著差异。在 5% 啶虫脒乳油中加入农用有机硅，能提高啶虫脒对烟粉虱的防效并减
少 5% 啶虫脒乳油 10%~40% 的施用量。【结论】生产上建议使用农用有机硅 3 000 倍液与 5% 啶虫脒乳油混用
防治烟粉虱。 |

| 【Objective】The tests were conducted to evaluate the synergistic effects of four kinds of additives, namely,
organosilicon, mixed orange essential oil, green peel orange oil and Jijian, on field control efficacy of acetamiprid against
Bemisia tabaci, and to evaluate the decrement effects of 3000-fold dilution of organosilicon on field control efficacy of
acetamiprid against B. tabaci. 【Method】 The field efficacy trials were conducted by spraying .The recommended dose of 5%
acetamiprid EC was mixed with organosilicon 3000-fold dilution, orange essential oil 1000-fold dilution, green peel orange
oil 1000-fold dilution and Jijian 3000-fold dilution, respectively, to determine the control efficacy of droplets density and
coverage rate of acetamiprid on B. tabaci and the decrement effects of 3000-fold dilution of organosilicon on field control
efficacy of acetamiprid against B. tabaci.【Result】The results showed that the recommended dose of 5% acetamiprid
EC mixed with additives could increase the droplets of the liquid. However, the recommended dose of 5% acetamiprid EC
mixed with different additives showed different control effects to B. tabaci. Among the tested additives, the organosilicon had
obvious synergistic effect and long persistent on acetamiprid against B. tabaci, followed by green peel orange oil, and there
was no significant difference between the mixed solution of orange essential oil and acetamiprid EC and branch water. 5% acetamiprid EC mixed with organosilicon could improve the control effect of B. tabaci, and reduce the application amount of
10%-40%.【Conclusion】5% acetamiprid EC mixed with organosilicon 3000-fold dilution can be used for the prevention and
control of B. tabaci in practice. |
