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. It was widely used in the agricultural industry until being phased out ...
Enlist Weed Control System. The Enlist Weed Control System is an agricultural system that includes seeds for genetically modified crops that are resistant to Enlist (a broadleaf herbicide with two active agents, 2,4-Dichlorophenoxyacetic acid (2,4-D) and glyphosate) and the Enlist herbicide; spraying the herbicide will kill weeds but not the ...
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.
Fenoprop, also called 2,4,5-TP, is the organic compound 2- (2,4,5-trichlorophenoxy)propionic acid. [2] It is a phenoxy herbicide and a plant growth regulator, an analog of 2,4,5-T in which the latter's acetic acid sidechain is replaced with a propionate group (with an extra CH 3 ). The addition of this extra methyl group creates a chiral centre ...
2,4,5-Trichlorophenol (TCP) is an organochloride with the molecular formula C 6 H 3 Cl 3 O.It has been used as a fungicide and herbicide. [2] Precursor chemical used in the production of 2,4,5-Trichlorophenoxyacetic acid (2,4,5-T) and hexachlorophene involves the intermediate production of 2,4,5-trichlorophenol (TCP) and the formation of 2,3,7,8-Tetrachlorodibenzodioxin (TCDD, commonly ...
Weeds controlled with herbicide. Herbicides ( US: / ˈɜːrbɪsaɪdz /, UK: / ˈhɜːr -/ ), also commonly known as weed killers, are substances used to control undesired plants, also known as weeds. [ 1] Selective herbicides control specific weed species while leaving the desired crop relatively unharmed, while non-selective herbicides ...
A 5–10 centimetres (2.0–3.9 in) layer of wood chip mulch prevents some weeds from sprouting. Gravel can serve as an inorganic mulch. Irrigation is sometimes used as a weed control measure such as in the case of paddy fields to kill any plant other than the water-tolerant rice crop.
Mechanical weed control is a physical activity that inhibits unwanted plant growth. [1] Mechanical, or manual, weed control techniques manage weed populations through physical methods that remove, injure, kill, or make the growing conditions unfavorable. Some of these methods cause direct damage to the weeds through complete removal or causing ...
