Application

Dichlorprop is primarily used as a post-emergence herbicide for controlling broadleaf weeds in wheat, barley, oats, and other cereal crops. It functions as a synthetic auxin, disrupting normal plant growth and leading to uncontrolled cell division and vascular tissue damage. Researchers also utilize Dichlorprop in studies investigating herbicide resistance mechanisms and environmental fate. Its selective action makes it valuable for integrated weed management systems.
