2,4-D works a synthetic auxin. It belongs to be family of phenoxycarboxylic acid. It is used on a wide variety of terrestrial and aquatic broadleaf weeds. It has little effect on grasses.
|
Mode of action

It is selective systemic herbicide. It acts as a growth inhibitor. The 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.
|
Applications
It is herbicide product based on 80% of active ingredients of 2,4-dichlorophynoxy acetic acidin soluble powder form in which sodium salt is present. It is a selective herbicide and controls broad leaved weeds, sedges and germinating grass seedling in crops like wheat, maize, citrus and grapes. It is rapidly absorbed by roots.
