SUMMARY

Dichlormid is a safener used with maize to protect from chloroacetanilide and thiocarbamate herbicides. It is not approved for use in the EU. It is highly soluble in water and is highly volatile. It is not usually persistent in soils. Dichlormid has a moderate mammalian toxicity with a high potential for bioaccumulation. It is also an irritant. It is relatively non-toxic to birds, fish and aquatic invertebrates.
