2,4-Dichlorophenoxyacetic acid is an organic compound with the chemical formula Cl 2 C 6 H 3 OCH 2 CO 2 H.It is usually referred to by its ISO common name 2,4-D. [4] It is a systemic herbicide that kills most broadleaf weeds by causing uncontrolled growth, but most grasses such as cereals, lawn turf, and grassland are relatively unaffected.
2,4-DB or 4-(2,4-dichlorophenoxy)butyric acid is a selective systemic phenoxy herbicide used to control many annual and perennial broad-leaf weeds in alfalfa, peanuts, soybeans, and other crops. Its active metabolite, 2,4-D, inhibits growth at the tips of stems and roots. It is classified in toxicity class III.
The combined effects of herbicides, nitrogen fertilizer, and improved cultivars has increased yields (per acre) of major crops by three to six times from 1900 to 2000. [3] In the United States in 2012, about 91% of all herbicide usage, determined by weight applied, was in agriculture.

Additional information on Roundup Ready crops is available on the GM Crops List. [6] As of 2005, 87% of U.S. soybean fields were planted with glyphosate resistant varieties. [7] [8]
In the same report, it added the "yield loss plus increased herbicide cost may result in an average estimated loss of $28 per acre" if atrazine were unavailable to corn farmers. [4] In 2006, the EPA concluded that the triazine herbicides posed "no harm that would result to the general U.S. population, infants, children or other... consumers." [5]
