Abstract

2,4-dichlorophenoxyacetic acid, commonly known as 2,4-D, is an herbicide used for selective control of broadleaf and grassy weeds in crops such as corn and wheat, along roadways and rights-of-way, and on pasture and rangeland. 2,4-D is the most widely used herbicide in the world, and the third most widely used in North America after metolachlor and atrazine. 2,4-D is a synthetic, organic, white to yellow, odorless, crystalline powder that dissolves readily in water. It is widely used today primarily because of its low cost.
