RESUMEN

Diuron is a pre-emergence herbicide that is approved for use in the EU. It has a low aqueous solubility, a low volatility and may, under certain conditions, leach to groundwater. It may be moderately persistent in soil systems and may also persist in water. It is moderately toxic to mammals and is classified as an irritant, It is moderately toxic to birds, earthworms, most aquatic species but is slightly more toxic to algae. It has a low toxicity to honeybees.
