Active ingredient | 2,4-D dimethyl amine salt | ||
Structural Formula | C10H13Cl2NO3 | ||
Classification | Herbicide / Agrochemical | ||
Mode of Action | 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 | 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. 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. | ||
Toxicity | Oral: Acute oral LD50 for rats 639-764, mice 138 mg/kg. Skin and eye: Acute percutaneous LD50 for rats >1600, rabbits > 2400 mg/kg. Skin and eye irritant (rabbits). A skin sensitiser (guinea pigs). Inhalation: LC50 (24 h) for rats >1.79 mg/l. | ||
