(Also known as: diallyldichloroacetamide; BRN 1768843)
SUMMARY
Dichlormid is a safener used with maize to protect from chloroacetanilide and thiocarbamate herbicides. 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.
Data alerts
The following alerts are based on the data in the tables below. An absence of an alert does not imply the substance has no implications for human health, biodiversity or the environment but just that we do not have the data to form a judgement.
