12.5%阿维菌素·啶虫脒微乳剂对螺旋粉虱的田间防效评价

Control Effect of 12. 5% Abamectin·acetamiprid Microemulsion to Aleurodicus dispersus

[目的]明确12.5％阿维菌素·啶虫脒微乳剂对螺旋粉虱的防治效果.[方法]于2009和2010年通过田间试验评价该药剂对螺旋粉虱的防治效果.[结果]药后1、3、7d该药剂用量为15.75 ～ 37.50 g/hm2时对螺旋粉虱的防治效果分别为66.00％ ～ 79.92％、80.81％ ～89.29％和74.18％ ～ 85.67％,均比对照药剂的防治效果高且差异显著.[结论]为螺旋粉虱的化学防控奠定了基础.

[Objective] The aim was to understand control effect of 12.5％ Abamectin acetamiprid microemulsion to A.disperses.[Method]The control effect of 12.5％ Abamectin · acetamiprid microemulsion to A.disperses was studied through field trials in 2009 and 2010.[Result] The control effects of 12.5％ Abamectin acetamiprid ME were 66.00％-79.92％,80.81％-89.29％,and 74.18％-85.67％ at the active ingredient dosages of 15.75-37.50 g/hm2 on the 1 st,34 and 7th days after spraying,respectively,which were significantly higher than the controls.[Conclusion] The results lay the basis for the chemical control of A.disperses.
