摘要：

为了筛选出对烟粉虱和烟蚜防治具有共同增效作用的桶混药剂组合,采用浸叶法测定鱼藤酮分别与噻虫胺、噻虫啉和噻虫嗪桶混后对烟粉虱和烟蚜的联合毒力,通过共毒系数筛选出效果较好的桶混组合,然后进行烟粉虱和烟蚜的田间药效试验。结果显示,12组桶混组合对烟粉虱有增效作用和6组桶混组合对烟蚜有增效作用,其中5组桶混组合对烟粉虱和烟蚜具有共同增效作用。当鱼藤酮与噻虫胺按有效成分3:20、14:25和13:25,与噻虫嗪按有效成分63:10和133:1配比时,对烟粉虱和烟蚜同时具有增效作用。田间药效试验结果显示,6%鱼藤酮微乳剂与20%噻虫胺悬浮剂桶混,药后1、3、7、10天对烟粉虱和烟蚜的防治效果分别在70%、90%、92%、88%以上;6%鱼藤酮微乳剂与25%噻虫嗪水分散粒剂桶混,药后1、3、7、10天对烟粉虱和烟蚜的防治效果分别达到74%、86%、91%、90%以上,其速效性优于6%鱼藤酮微乳剂的防治效果,持效性优于化学杀虫剂的防治效果。鱼藤酮与3种新烟碱类杀虫剂桶混增效作用显著,为烟粉虱和烟蚜的田间农药减量化防控提供了理论基础。

Abstract:

In order to screen out the synergistic tank mixtures that have a synergistic effect on the control of Bemisia tabaci Gennadius and Myzus persicae Sulzer, the leaf dip method was used to determine the co-toxicity of rotenone with clothianidin, thiacloprid and thiamethoxam. The tank mixtures with better effect were screened through the co-toxicity coefficient, and then the field efficacy test on Bemisia tabaci Gennadius and Myzus persicae Sulzer was carried out. The results showed that 12 groups of tank mixtures had a synergistic effect on Bemisia tabaci Gennadius and 6 groups of tank mixtures had a synergistic effect on Myzus persicae Sulzer. Among them, 5 groups of tank mixtures have synergistic effects on both Bemisia tabaci Gennadius and Myzus persicae Sulzer. When rotenone and clothianidin were proportioned according to the active ingredients of 3:20, 14:25 and 13:25, and rotenone and thiamethoxam were proportioned according to the active ingredients of 63:10 and 133:1, all combinations had synergistic effects on Bemisia tabaci Gennadius and Myzus persicae Sulzer. Field efficacy test results showed that the control effects of the tank mixtures of 6% rotenone microemulsion with 20% clothianidin suspension on Bemisia tabaci Gennadius and Myzus persicae Sulzer were 70%, 90%, 92%, 88% at 1, 3, 7 and 10 days after treatment respectively. The control effects of the tank mixtures of 6% rotenone microemulsion with 25% thiamethoxam water dispersible granules on Bemisia tabaci Gennadius and Myzus persicae Sulzer reached 74%, 86%, 91%, and 90% at 1, 3, 7 and 10 days after treatment respectively. The quick-acting effect was better than the control effect of 6% rotenone microemulsion, and the lasting effect was better than the control effect of chemical pesticides. Rotenone and 3 kinds of neonicotinoid insecticides have a significant synergistic effect in tank mixtures, and the study could provide a theoretical basis for the field pesticide reduction control of Bemisia tabaci Gennadius and Myzus persicae Sulzer.
