Some active ingrediants in plant weed killers either disrupt the metabiolic processes of the cells - causing them to abort and die, or they may actually stimulate and over growth within the plant, where the plant is unable to take up sufficient nutrients to keep up with the increased growth rate - effectively growing the plant to death.

∙ 11y agoPlant hormones such as auxin work well in weed killers. It seems that these chemicals are taken up more easily by plants with two cotyledons more easily than monocotyledon plants. the chemicals in the weed killer then change the growth patters of the plant. these new growth patters of the plant result n the production of another plant hormone ethylene. there is probably more behind how plant hormones work as plank killers. the truth is not really known about it. the hypothesis is that the chemicals in the weed killer stop production of chemicals that the plant needs for growth.
