Metaflumizone (Ref: BAS 320l)
Last updated: 18/02/2021
(Also known as: NNI 0250)

SUMMARY
Metaflumizone is a semicarbazone broad-spectrum insecticide. It has a low aqueous solubility, is non-volatile and a low potential for leaching to groundwater based on its chemical properties. It is persistent in soil and in water-sediment systems. It has a low mammalian toxicity and considered to have potential negative reproduction/developmental effects. It also has a high potential for bioaccumulation. It has a low to moderate toxicity to most birds, aquatic species, honeybees and earthworms.
