Application
Chemical name：2,4-D
Use category：Herbicide
Content & formulation：2,4-D 98% TC , 2,4-D 720 g/L SL , 2,4-D 860 g/L SL , 2,4-D 600 g/L SL
Structure Formula：
Common Name：2,4-D (BSI, E-ISO, (m) F-ISO, WSSA); 2,4-PA (JMAF)
CAS No.：94-75-7
CAS Name：(2,4-dichlorophenoxy)acetic acid
Molecular Formula：C8H6Cl2O3
Agrochemical Type：Herbicide,phenoxycarboxylic acids
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.

Application：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.
