SUMMARY

Bendiocarb is a carbamate insecticide and veterinary treatment that does not have EU regulatory approval for use. It has a moderate aqueous solubility, moderate volatility, is moderately mobile but, based on its chemical properties, would not be expected to leach to groundwater. It is highly toxic to mammals but tends not to bioaccumulate. It has a moderate to high toxicity for most aquatic organisms. It is highly toxic to birds and honey so but slightly less to earthworms.

GENERAL INFORMATION
