Use Profile:
2,4-D comes in multiple chemical forms is found in numerous end-use products intended fuse in a wide range of use patterns. 2,4-D is an ingredient in approximately 660 agricultural home use products, as a sole active ingredient in conjunction with other active ingredients. 2,4-D is formulated primarily as an amine salt in an aqueous solution as an ester in an emulsifiable concentrate.
Type of Pesticide: Herbicide
Targetganism(s): A wide variety of broadleaf weeds aquatic weeds
Mode of action:
2,4-D is thought to increase cell-wall plasticity, biosynthesis of proteins the production of ethylene. The abnormal increase in these processes is thought to result in uncontrolled cell division growth which damages vascular tissue.
