SUMMARY
Bensultapis an insecticide that is not approved for use in the EU. It has a low aqueous solubility, is quite volatile and not expected to leach to groundwater. It is not persistent in soil systems but may be persistent in water under some environmental conditions. Bensultap is moderately toxic to mammals and most species of fauna and flora.
