(Also known as: prometone; 2,4-prometone) |
SUMMARY |
Prometon is a non-selective herbicide without EU regulatory approval for use. It is highly soluble in water, volatile and, based on its chemical properties, it is highly mobile and has a high potential to leach to groundwater. It can be highly persistent in both soil and aquatic systems. It has a relatively low mammalian toxicity and is not expected to bioaccumulate. It is classified as an irritant. It is moderately toxic to birds, most aquatic species and honey bees. |
