(Not known by any other names)

SUMMARY

Carbanolate is an obsolete carbamate insecticide that is not approved for use in the EU. It has a moderate aqueous solubility. There are significant gaps in reported data for environmental fate and ecotoxicity. However, it is highly toxic to mammals and likely to bioaccumulate. It is also a neurotoxin and an acetyl cholinesterase inhibitor.
