2,4-Dichlorophenoxyacetic acid is an organic compound with the chemical formula Cl2C6H3OCH2CO2H. 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.
23 kwi 2023 · 2,4-D herbicides kill most broadleaf weeds in lawns but not grassy weeds. This makes it safe to apply on lawns infested with weeds. You can also apply it on driveways, gravel areas, fence rows, ornamental turf areas, drainage areas, and patios.
20 sty 2017 · New uses for 2,4-D, sometimes enabled by biotechnology, continue to be developed. This review strives to provide an overall understanding of 2,4-D activity in plants, plant sensitivity to 2,4-D, toxicological impacts, and current and future uses.
2,4-D (2,4-dichlorophenoxy) is a systemic phenoxy herbicide developed in the 1940s and still in use today. 2,4-D was the first widely used herbicide used to control broadleaf plants, and it has significantly contributed to modern weed control in agriculture.
15 mar 2016 · 2,4-D weed killer is a toxic herbicide that comes with known health risks. Learn about this dangerous chemical and why you should stay away.
2,4-D kills broadleaf weeds but not most grasses. 2,4-D kills plants by causing the cells in the tissues that carry water and nutrients to divide and grow without stopping. Herbicides that act this way are called auxin-type herbicides.
According to the International Programme on Chemical Safety (IPCS), alkali or amine salts or esters of 2,4-D are used as herbicides against broad-leaf weeds in cereal crops, as well as on pastures and lawns, at rates of about 0.2-2.0 kg ha-1 active ingredient (acid equivalent).
