2,4-Dichlorophenoxyacetic acid is an organic compound with the chemical formula C8H6Cl2O3 which is usually referred to by its ISO common name 2,4-D. It is a systemic herbicide which kills most broadleaf weeds by causing uncontrolled growth in them but most grasses such as cereals, lawn turf, and grassland are relatively unaffected.

2,4-D is one of the oldest and most widely available herbicides and defoliants in the world, having been commercially available since 1945, and is now produced by many chemical companies since the patent on it has long since expired. It can be found in numerous commercial lawn herbicide mixtures, and is widely used as a weedkiller on cereal crops, pastures, and orchards. Over 1,500 herbicide products contain 2,4-D as an active ingredient.


2,4-D is an herbicide that kills plants by changing the way certain cells grow. 2,4-D comes in several chemical forms, including salts, esters, and an acid form. The toxicity of 2,4-D depends on its form. The form also affects what will happen to 2,4-D in the environment and what impacts it may have, especially on fish. 2,4-D is used in many products to control weeds, and it is often mixed with other herbicides in these products.

2,4-D was first used in the United States in the 1940s. Agent Orange, an herbicide used during the Vietnam War, contained both 2,4-D and 2,4,5-T. Dioxin, a by-product of 2,4,5-T, led to the ban of Agent Orange.

Features of 2 4 D Weed Killer/2 4 D Herbicide

One of the cheapest and most common weed killers in the country has a name you’ve probably never heard: 2,4-D. Developed by Dow Chemical in the 1940s, this herbicide helped usher in the clean, green, pristine lawns of postwar America, ridding backyards everywhere of aesthetic undesirables like dandelion and white clover. But 2,4-dichlorophenoxyacetic acid, as it’s known to chemists, has a less wholesome side. There’s a growing body of scientific evidence that the chemical poses a danger to both human health and the environment.

The pesticide, which allows not just grasses but also fruits and vegetables to flourish, can attack both the roots and leaves of weeds by making the unwanted plant’s cells grow out of control—sort of like inducing cancer in the plant to kill it or drastically slow its spread. It’s used widely in agriculture in soybean, corn, sugarcane, and wheat fields, and it turns up in most “weed and feed” products as well as in many lawn treatments. The problem is, the herbicide that was once considered clean and green may no longer be safe by today’s standards.
