    2,4-Dichlorophenoxyacetic acid is a synthetic auxin and an analogue of indoleacetic acid. Application 2,4-Dichlorophenoxyacetic acid has been used as a supplement in: • Murashige and Tucker medium for thin cell layer explant culture • Murashige and Skoog medium media to initiate callus. Synthetic auxin, that is, 2,4-dichlorophenoxyacetic acid (2,4-D) is the first herbicide, which was developed at the commercial scale to use as a broadleaf herbicide. It selectively kills .

    Introduction The structures of 2,4-dichlorophenoxyacetic acid (2,4-D) and of chemically-related phenoxy herbicides in common use are given in Fig. 1. Some physical properties of 2,4-D and of the 2,4-D derivatives that are used in agriculture are summarized in Table 1. Table 1. 2,4-Dichlorophenoxyacetic acid being an auxin can support embryogenesis and callus formation at low concentrations, and have herbicidal activity at high concentrations, 2,4-D 2,4-Dichlorophenoxyacetic (2,4-D) Acid Solution (10 mg/mL)Concentration: 10 mg/mL.

    2,4-D is the common name for 2,4-dichlorophenoxyacetic acid, the active ingredient in several herbicides manufactured by Dow AgroSciences, a wholly owned subsidiary of The Dow Chemical Company. It is readily absorbed through plant leaves and roots. 2,4-D is a systemic herbicide that. 2,4-Dichlorophenoxyacetic acid (2,4-D) CASRN IRIS Summary (PDF) (9 pp, K) Status: EPA announced in a Federal Register Notice that chemicals used as pesticides would not be re-assessed by the IRIS Program.

The two active ingredients in Agent Orange were equivalent amounts of: 2,4-dichlorophenoxyacetic acid (2,4-D) and 2,4,5-trichlorophenoxyacetic acid (2,4,5-T), with trace amounts of 2,3,7,8-tetrachlorodibenzo-p-dioxin (also known as TCDD or dioxin).

Appraises the risks to organisms and ecological systems posed by the use of 2,4-dichlorophenoxyacetic acid (‎2,4-D)‎, a selective herbicide which kills broad-leaved plants but not grasses or conifers.

The herbicide, 2,4-dichlorophenoxyacetic acid (2,4-D), is an example of a pesticide for which the epidemiology data are continually reviewed and debated. Recently re-registered for use by Health Canada (), and the US Environmental Protection Agency, EPA (), 2,4-D is currently being re-evaluated by the European by: 2,4-D (2,4-dichlorophenoxyacetic acid) is a herbicide in the phenoxy or phenoxyacetic acid family that is used postemergence for selective control of broadleaf weeds.

Residents and professional applicators may use 2,4-D on home lawns. The novel complex photocatalytic material was prepared by coating TiO2 nanoparticles on tourmaline using the sol-gel method, and used in the degradation of the herbicide 2,4-D. The results indicated that coating TiO2 with tourmaline enhanced the photocatalytic activity significantly.
