Chlorfluazuron 50g/l EC of Insecticide PesticideChlorfluazuron is an insecticide that is not approved for use in the EU. It has a low aqueous solubility, is not highly volatile and, based on its physico-chemical properties it would not normally be expected to leach to groundwater. It is moderately persistent in soil systems and may persist in water under certain conditions. It has a low mammalian oral toxicity and an eye irritant. Ecotoxicological data is cant but chlorfluazuron is not highly toxic to birds or fish but is much more toxic to aquatic invertebrates.
