有些除草剂可以作用于植物的内源激素,对植物体内的生理生化过程产生影响。激素型除草剂的特点是低浓度时促进植物生长,高浓度时抑制生长,浓度更高时毒杀植物。目前已经在生产上应用的激素型除草剂有5类。 Some herbicides act on endogenous hormones in plants and have an impact on the physiological and biochemical processes in plants. Hormonal herbicides are characterized by low concentrations of plant growth, inhibit growth at high concentrations, higher concentrations kill poisonous plants. There are currently five types of hormonal herbicides that have been used in production.
