DESCRIPTION
2, 4-D is used on a wide variety of terrestrial and aquatic broadleaf weeds. It has little effect on grasses. It belongs to the family of phenoxycarboxylic acid.
Mode of action
It appears to work by causing uncontrolled cell division in vascular tissue. Abnormal increases in cell wall plasticity, biosynthesis of proteins, and production of ethylene occur in plant tissues following exposure, and these processes are responsible for uncontrolled cell division. The ester forms of 2, 4-D penetrate foliage, whereas plant roots absorb the salt forms. High concentrations may cause leaf burn and poor translocation leading to poor weed control. Translocated both up and down from the site of application to sources of active growth.
Applications
2, 4-D appears to be similar in action to other auxin-type herbicides.
2,4-D amine salt is a selective and herbicide effective against broadleaved weeds in sorghum, maize,wheat , aquatic weeds, Potato, Sugarcane & non cropped areas post emergence.
Mode of application used is blanket spray.
