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.
Enlist Duo is an herbicide that contains the choline form of 2,4-Dichlorophenoxyacetic acid (2,4-D) and glyphosate plus an unknown number of unlisted ingredients. Dow added chemicals to the mixture in what it termed "Colex-D technology". [5] 2,4-D is one of the most widely used herbicides in the world.
US Geological Survey estimate of 2,4-D use in the USA to 2019 The use of herbicides in US agriculture is mapped by the US Geological Survey. As of 2019 [update] , 2,4-D was the most used of the auxins. 45,000,000 pounds (20,000,000 kg) were sprayed that year, [ 5 ] compared to 2,000,000 pounds (910,000 kg) of the next most heavily applied, MCPA ...
