Abstract: 【Objective】 The objective of this study was to determine the control effect of 0.3% matrine on cotton aphids, and compound it with 8 pesticide adjutants under the condition of matrine reduction, and evaluate its control effect. The types of pesticide additives and the use of technology, to guide farmers to scientifically reduce drugs, rational drug selection, safe drug delivery theory.【Method】 In 2019, 0.3% matrine water agent and 8 kinds of auxiliaries were used in the Aral cotton-growing region. The spraying methods were used to spray-10%+adjuvants, -20%+ adjuvants, -30%+adjuvant as different chemical treatments, and clear water was used as a control. The number of insects was investigated before the drug, 1 d, 3 d, 5 d and 7 d after the drug, and the control effects were analyzed.【Result】 The effect of 0.3% matrine with 200 mL/667m2 on cotton aphid in 59.08%-81.34%, and the decrease rate of pest population was 59.34%-77.47%. The control effect of 0.3% matrine on cotton aphids, and compound it with 8 pesticide adjuvants under the condition of matrine reduction 10%-30% was 37.76%-81.16%, among which the addition of Jijian was the best for cotton aphid, while the treatment with green orange oil was the least effective.【Conclusion】 After the reduction of 0.3% matrine and the Jijian, Sirun and Feng zhan, the control effect on cotton aphid were better than those of the combination of Orange peel oil and Green orange peel oil under the same reduction condition of matrine.

摘要: 【目的】测定0.3%苦参碱对棉田蚜虫的防效,研究在苦参碱减量的情况下与8种农药助剂复配的防治效果,筛选最佳用量和助剂种类,为合理选药、科学减药、安全施药提供技术支撑。【方法】2019年在阿拉尔地区选用0.3%苦参碱水剂和8种助剂复配,采用茎叶喷雾法,分别喷施正常用量、减量10%+助剂、减量20%+助剂、减量30%+助剂作为药剂处理,清水作为对照,测定并计算药后1、3、5和7 d的田间防效。【结果】0.3%苦参碱药量为200 mL/667m2对棉蚜的防效在59.08%~81.34%,虫口减退率在59.34%~77.47%,减量10%~30%与助剂复配后对棉蚜的防治效果为37.76%~81.16%,其中添加激健对棉蚜的防效最好,减药20%用量下与正常用量的防效差异不明显。【结论】激健、丝润和丰展等助剂与0.3%苦参碱减量20%配合使用,对棉蚜的防治效果与正常使用剂量相当,增效减量作用明显,优于橙皮精油、青皮桔油等助剂。
