Alpha-cypermethrin 97% TC of Insecticide Pesticide

Alpha-cypermethrin is a widely used pyrethroid insecticide that is approved for use in the EU. It has a low aqueous solubility, in relatively volatile and, based on its chemical properties, is not expected to leach to groundwater. However, it is considered to be a serious water pollutant. It is moderately persistent in soil and has been known to persist in water. It is highly toxic to mammals and a recognised irritant. It is relatively non-toxic to birds but is highly toxic to most aquatic organisms and honeybees. Alpha-cypermethrin is moderately toxic to earthworms.
