Insecticide Pesticide & Acaricide Miticide Diafenthiuron 50% WPDiafenthiuronDiafenthiuron is an insecticide and acaricide without regulatory approval for use in the EU. It has a low aqueous solubility but is readily soluble in many organic solvents. It is volatile and, based on its chemical properties, it is unlikely to leach to groundwater. It is not persistent in most soil systems but may be very persistent in aquatic systems. It has a low mammalian toxicity but is moderate to highly toxic for most biodiversity including aquatic life, bees and worms.
