Aziprotryne (Ref: C 7019)

(Also known as: aziprotryn; mesanoril; aziprotyne)

Aziprotryne is a herbicide that is considered obsolete. It is moderately soluble in water, volatile and not expected to leach to groundwater. Little is known about its environmental persistence. Data suggests it is not highly toxic and is not expected to bioaccumulate. It is not highly toxic to birds and is considered moderately toxic to fish.

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.
