Application of mulberry branch extract in prevention and treatment of aphids

The invention discloses application of a mulberry branch extract in prevention and treatment of aphids. Mulberry branches are mulberry branches with barks. Insecticidal experiments prove that the mulberry branch extract can have high insecticidal activity on aphids, especially aphis gossypii glover and cotton aphid, and the mortality rate of the aphids can reach 100% when the mulberry branch extract is compounded with the mulberry branch extract. Natural mulberry resources can be comprehensively utilized, the preparation method is simple, materials are easy to obtain, the cost is low, and a new direction can be provided for development and utilization of the mulberry resources; the compound has high insecticidal activity, is green and pollution-free, and provides a new direction for development of green and safe botanical pesticides. 本发明公开桑树枝提取物在防治蚜虫中的应用，所述桑树枝为带皮桑树枝杆。经过杀虫实验验证，桑树枝提取物可对蚜虫，特别是瓜蚜、棉蚜具有较高的杀虫活性，且其与桑树叶提取物复配，蚜虫的死亡率可达到100％。本发明可综合利用天然的桑树资源，制备方法简单，材料易得，成本低廉，可为桑树资源的开发利用提供新的方向；并且其具有较高的杀虫活性，且绿色，无公害，为绿色、安全的植
