It is a selective broad-spectrum post-emergence herbicide.
It is used to control weeds in a variety of crops.
It is absorbed by the roots and foliage and acts as a growth inhibitor.
MODE OF ACTION: 2,4-Dichlorophenoxyacetic acid (2,4-D) was the first synthetic herbicide to be commercially developed and has commonly been used as a broadleaf herbicide for over 60 years.
It is a selective herbicide that kills dicots without affecting monocots and mimics natural auxin at the molecular level.
Physiological responses of dicots sensitive to auxins herbicides include abnormal growth, senescence, and plant death.
The identification of auxin receptors, auxin transport carriers, transcription factors response to auxin, and cross-talk among phytohormones have shed light on the molecular action mode of 2,4-D as a herbicide.
APPLICATION:
Best results are obtained when the product is applied to young succulent weeds that are actively growing.
he lower recommended rates will be satisfactory on susceptible annual weeds.
For perennial weeds and conditions such as the very dry areas of the western states where control is difficult, the higher recommended rates should be used.When a product is used for weed control in crops, the growth stage of the crop must be considered.
Some plants and weeds, especially woody varieties, are difficult to control and may require repeat applications if permitted by this label.
