Herbicide - 2,4-D

NOMENCLATURE 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 2,4-D-dimethylammonium CAS RN [2008-39-1] 2,4-D-sodium CAS RN [2702-72-9]


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.


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.
