2,4-Dichlorophenoxyacetic acid (called 2, 4-D) is a common systemic herbicide used for the control of broadleaf weeds. Developed during World War II for the purpose of increasing crop yields, today it is of the most widely used herbicides in the world.
2,4-D belongs to a class of plant hormones called synthetic auxins which are absorbed through plant leaves and then trans-located to the meristems. This causes uncontrolled and unsustainable growth that results in the withering of leaves and stems and eventual death.
2, 4-d Uses
2,4-D is most often used in the control of broadleaf weeds in lawns and turf, cereal grains, corn, sorghum, grass hayfields, pastures, brush along fences and highway, and railroad rights of way.
2, 4-d Toxicity
Products containing 2, 4-D must include the word DANGER on the label to indicate a high level of toxicity.
