摘要: 将辣蓼(Polygonum hydroiper L.)粗提物作为植物源农药进行简便制备并用于烟草地下害虫的防治。结果表明,辣蓼粗提物能有效防治栽后5~15 d烟草地下害虫,防虫效果持续时间长且对烟叶生长无不良影响,防效可达45%~80%;干草固液混合物根部液浇法地下害虫为害率与对照(CK)达极显著水平,与高效氯氟氰菊酯处理达显著水平,栽后5~15 d防效达66%~80%,较普遍使用的高效氯氟氰菊酯防效可提升35%~60%。

Abstract: : The crude extract of Polygonum hydroiper was used as a plant source pesticide to prevent and control the underground pest of tobacco. The experiment showed that the crude extract of Polygonum hydroiper could effectively prevent and control the underground insect of 5~15 days after planting. It had long duration and no effect on the growth of tobacco, and the control effect could reach 45%~80%; The control efficacy of liquid mixture was 66%~80%, and it was 35%~60% higher than that of the efficacy of high performance permethrin.

Key words: Polygonum hydroiper, tobacco, underground pest, control effect
