(Also known as: tricyclotin) |
SUMMARY |
Azocyclotin is an organotin acaricide that is not approved for use in the EU and largely considered obsolete. It has a low aqueous solubility, is non-volatile and is not expected to leach to groundwater. Data is limited but is not expected to be persistent in soil systems but may be persistent in aquatic systems under certain conditions. It is highly toxic to mammals and also has a high potential to bioaccumulate. It is thought to be a skin, eye and respiratory system irritant. It is highly toxic to fish and aquatic invertebrates and moderately toxic to birds, honeybees and earthworms. |
