SUMMARY

Benfuracarb is a carbamate insecticide and nematicide that does not have EU regulatory approval for use. It has a low aqueous solubility, is relatively volatile and is not expected to leach to groundwater. It is not persistent in soil or water systems. It has a moderate mammalian toxicity with a low bioaccumulation potential. It is highly toxic to most aquatic organisms, birds and honeybees but slightly less so to earthworms.
