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.

Chemical structure of 2,4-D, the prototypical chlorophenoxy herbicide. Chlorophenoxy herbicides are a subclass of phenoxy herbicides which includes: MCPA, 2,4-D, 2,4,5-T and mecoprop. [1] Large amounts have been produced since the 1950s for agriculture. [2]
2,4,5-Trichlorophenoxyacetic acid (also known as 2,4,5-T), a synthetic auxin, is a chlorophenoxy acetic acid herbicide used to defoliate broad-leafed plants. It was developed in the late 1940s, synthesized by reaction of 2,4,5-Trichlorophenol and chloroacetic acid.
Roundup was the first glyphosate-based herbicide, developed by Monsanto in the 1970s. It is used most heavily on corn, soy, and cotton crops that have been genetically modified to be resistant to the herbicide. Some products include two active ingredients, such as Enlist Duo which includes 2,4-D as well as glyphosate. As of 2010, more than 750 ...
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.
Atrazine is a chlorinated herbicide of the triazine class. [2] It is used to prevent pre-emergence broadleaf weeds in crops such as maize (corn), [3] soybean [3] and sugarcane and on turf, such as golf courses and residential lawns.
