SUMMARY

Dienochlor is an obsolete organochlorine insecticide that does not have regulatory approval for use in the EU. It has a low aqueous solubility and is quite volatile. Its data suggests it is persistent in soils. It is not toxic to mammals but does high a potential for bioaccumulation. Dienochlor has a moderate toxicity to aquatic invertebrates but considered to be more toxic to fish. It is relatively non-toxic to birds
