Flonicamid (Ref: IKI 220)	Last updated: 31/10/2024
(Also known as: F 1785)

SUMMARY

Flonicamid is a systemic pyridine insecticide used in the field and in glasshouses. It has a high aqueous solubility and a low volatility. Evidence suggests it is not persistent in soil but may be in aquatic systems. Based on physico-chemical properties, there is some risk that the substance may to leach to groundwater. Ecotoxicity is moderate to low for most species. It has a moderate mammalian oral toxicity. It may be a liver and kidney toxicant.
