Bioallethrin
(Also known as: allethrin; esbiol; esdeballethrin; esbiothrin)
SUMMARY
Bioallethrin is an insecticide. It has a low aqueous solubility, is volatile and would not normally be expected to leach to groundwater. It is moderately persistent in soil and, under certain conditions, could be persistent in water. It is moderately toxic to mammals, is an endocrine distrupter and an eye irritant. Bioallethrin is highly toxic to fish but less so to birds and honeybees.
