Ethylene dibromide (EDB) is used as intermediate in organic synthesis, for example to manufacture herbicide DIQUAT, also applied as soil fumigant to treat nematode (known as nematocide), wireworms, and other soil pests. Normally it can be fomulated with chloropicrin to improve efficiency. EC grade is also applied.
