Anilazine is a fungicide that no longer has approval for use in the EU. It has a low aqueous solubility, non-volatile and presents a low risk of leaching to groundwater. Whilst it is not highly toxic to humans there are some concerns regarding its potential to bioaccumulate. It is highly toxic to fish and moderately toxic to most other aquatic organisms, birds, honeybees and earthworms.
