Application |
| |
|
2,4D is a 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 be also be used as a plant growth
regulator to prevent premature fruit fall in citrus fruit.
