Bioresmethrin (Ref: FMC 17370)
Last updated: 13/01/2023
(Also known as: bioresmethrine; NRDC107; biobenzylfuraline; benzofuroline)
Bioresmethrin is a broad spectrum pyrethroid insecticide. It hasd a low aqueous solubility and is moderately volatile. It is not thought to be environmentally persistent and, based on its physicochemical properties, would not be expected to leach to groundwater. Bioresmethrin is highly toxic to fish, aquatic invertebrates and honey bees. It as a low mammalian oral toxicity but may be a respiratory irritant.
The following alerts are based on the data in the tables below. An absence of an alert does not imply the substance has no implications for human health, biodiversity or the environment but just that we do not have the data to form a judgement.
