氟乐灵是选择性芽前二硝基苯胺类除草剂,氟乐灵在植物体内严重抑制细胞有丝分裂与分化,破坏核分裂,被认为是一种细胞核的毒害剂。浓度越高,对细胞有丝分裂的抑制作用越重。在生化反应上,它抑制脂类的代谢和DNA的合成,同时也影响蛋白质合成和氨基酸的组成,干扰植物激素的产生和传导,因而使植物死亡。氟乐灵通过杂草种子发芽生长穿过土层的过程中被吸收,但 Trifluralin is a selective pre-emergent dinitroaniline herbicide. Trifluralin inhibits cell mitosis and differentiation in plants and disrupts nuclear fission. It is considered as a nuclear poison. The higher the concentration, the greater the inhibitory effect on mitosis. In the biochemical reaction, it inhibits lipid metabolism and DNA synthesis, but also affects protein synthesis and amino acid composition, interfering with the production and conduction of plant hormones, thus causing plant death. Trifluralin is absorbed during the process of germination of weed seeds that grow through the soil layer
