RESUMEN

Dicamba is a selective, systemic herbicide approved for use in the EU and used for general weed control. It is highly soluble in water, volatile and has a low potential to leach to groundwater based on its chemical properties. It is not persistent in soil but, under certain conditions, it may persist in aquatic systems. It is moderately toxic to mammals but has a low potential to bioaccumulate. It is an irritant. it is moderately toxic to birds, most aquatic species, honeybees and earthworms.
