2, 4-D systemic auxin plant Non Selective Herbicide for broadleaf weed

2, 4-Dichlorophenoxyacetic acid (2, 4-D) systemic auxin plant Non Selective Herbicide for broadleaf weed

Common name: 2, 4-D (BSI, E-ISO, (m) F-ISO, WSSA); 2, 4-PA (JMAF)

IUPAC name: (2, 4-dichlorophenoxy)acetic acid

Chemical abstracts name:(2, 4-dichlorophenoxy)acetic acid

CAS RN: [94-75-7]

EEC no.: 202-361-1

Introduction: There are many forms or derivatives of 2, 4-D including esters, amines, and salts. Unless otherwise specified, this document will refer to the acid form of 2, 4-D. 2, 4-D, a chlorinated phenoxy compound, functions as a systemic herbicide and is used to control many types of broadleaf weeds. It is used in cultivated agriculture, in pasture and rangeland applications, forest management, home, garden, and to control aquatic vegetation. It may be found in emulsion form, in aqueous solutions (salts), and as a dry compound. The product Agent Orange, used extensively throughout Vietnam, was about 50% 2, 4-D. However, the controversies associated with the use of Agent Orange were associated with a contaminant (dioxin) in the 2, 4, 5-T component of the defoliant.

Trade and Other Names: 2, 4-D is used in many commercial products. Commercial names for products containing 2, 4-D include Aqua-Kleen, Barrage, Lawn-Keep, Malerbane, Planotox, Plantgard, Savage, Salvo,

Formulation: It may be found in emulsion form, in aqueous solutions (salts), and as a dry compound.

Mode of action: It is a selective systemic herbicide. Salts are readily absorbed by the roots, whilst esters are readily absorbed by the foliage. Translocation occurs, with accumulation principally at the meristematic regions of shoots and roots. Acts as a growth inhibitor.

Uses: 2.4 D herbicide is used for post-emergence control of annual and perennial broad-leaved weeds in cereals, maize, sorghum, grassland, established turf, grass seed crops, orchards (pome fruit and stone fruit), cranberries, asparagus, sugar cane, rice, forestry, and on non-crop land (including areas adjacent to water), at 0.28-2.3 kg/ha. It is also used for the control of broad-leaved aquatic weeds. The isopropyl ester can also be used as a plant growth regulator to prevent premature fruit fall in citrus fruit.

Phytotoxicity: Phytotoxic to most broad-leaved crops, especially cotton, vines, tomatoes, ornamentals, fruit trees, oilseed rape and beet.
