摘　　要：针对目前枣树上红蜘蛛危害严重与抗药性突出的问题,试验研究了不同浓度的藜芦碱可溶液剂对枣树红蜘蛛的防治效果,为农药的轮换施用、交替使用提供可靠的理论与应用基础。结果表明,0.5%藜芦碱可溶液剂用量在600倍时,施药7 d后防治效果高达90%以上;且在该浓度下防治枣树红蜘蛛的速效性和持效性均良好,施药后14 d防治效果仍高达95%以上。因此,0.5%藜芦碱可溶液剂能有效控制枣树红蜘蛛,应用效果比较理想,作为生物农药可在生产中与其他药剂交替使用。In view of the serious damage and drug resistance of red spider on jujube tree, the control effect of different concentrations of veratrine solution on red spider on jujube tree was studied, in order to provide reliable theoretical and application basis for alternate application of pesticide. The results showed that when the dosage of 0.5% veratrine solution was 600 times, the control effect was as high as 90% after 7 days of application;And at this concentration, the control of jujube red spider is quick and effective, and the control effect was still up to 95% in 14 d after application. Therefore, 0.5% veratrine can effectively control red spider of jujube tree, and its application effect is ideal. As a biological pesticide, it can be used alternately with other pesticides.
