Description and Uses
2,4-DB is a post-emergence herbicide that is used to control broadleaved weeds. It is highly soluble in water and most organic solvents. It is relatively volatile but it may leach to groundwater under certain conditions. It is not persistent in soil systems but may tend to be persistent in aquatic systems. It is moderately toxic to mammals and there is some concern regarding its potential for bioaccumulation. It is moderately toxic to birds, earthworms, honeybees and most aquatic organisms.
4-(2,4-Dichlorophenoxy)butanoic Acid is a herbicide.
