RESUMEN

Dichlobenil is a herbicide that was largely used for general annual and perennial weed control in non-copped. It is no longer approved for use within the EU. It has low solubility, is not highly volatle and has potential to leach into groundwater. It is moderately persistent in soils and very persistent in water. It is moderately toxic to mammals, aquatic organisms, honeybees and earthworms.
