| 摘 要： | 介绍了以敌草快、百草枯为代表的联吡啶类除草剂的主要作用机制和选择机理,对该类农药在环境中的行为进行了归纳和探讨,指出该类除草剂对气候条件的影响并不特别敏感,挥发性亦不强,而与土壤的结合能力较强。展望了对其作用机制和环境行为的研究将进一步深入的前景。

| Abstract: | In this paper,effects and selectivity mechanism and environment behaviors of bi-pyridine herbicides were described.The both herbicides are characterized by non-selective and widely applied on potato production as defoliant,for example.Acting mechanism of the herbicides is shown by inhibiting photosynthesis of plants.These herbicides are likely to become corresponding conjugated compounds in soil with clay minerals.This reaction may be influenced by several environmental factors,such as pH. |
