The herbicide takes effect quickly after application. It is registered in every US state. [6] It should be sprayed when the soil is well worked and dry, to allow good mixing and incorporation. It can be stored at temperatures as low as -50 °F. [7] It is not persistent in soil, having a half-life of about 6 days. [1]

As a herbicide, it was introduced in 1962, [2] and it quickly became the fourth most used herbicide in the US, with 28.5 million pounds (12.9 thousand tonnes) used in 1974. [4] Its use has declined significantly, to 15 million pounds (6.8 thousand tonnes) in 1991 to 950 thousand pounds (430 tonnes) by 1998.
The term includes any derivatives of a pesticide, such as conversion products, metabolites, reaction products and impurities considered to be of toxicological significance. The term “pesticide residue” includes residues from unknown or unavoidable sources (e.g. environmental) as well as known uses of the chemical.
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.
To prevent growth of crabgrass, preemergent herbicides must be applied at a critical time. If they are applied to the soil too early, they get washed too deep into the soil or washed away by rainwater. If they are applied too late, the key enzyme inhibited is no longer active. The best control requires a second application about 6–8 weeks later.
Mixing time may refer to: Blend time , the time to achieve a predefined level of homogeneity of a flow tracer in a mixing vessel Mixing (mathematics) , an abstract concept originating from physics used to attempt to describe the irreversible thermodynamic process of mixing
