Chlorpyrifos-methyl (Ref: OMS 1155) |
Last updated: 23/08/2024 |
(Also known as: ENT 27520; Dowco 214; chlorpyriphos-methyl; chlorpyrifos-me) |
SUMMARY |
An organophosphate broad-spectrum insecticide. It has a low aqueous solubility, is quite volatile and is non-mobile. There is a low risk of leaching to groundwater based on its chemical properties. It tends not to be persistent in soil or water systems. It is not highly toxic to mammals but is classified as an acetyl cholinesterase inhibitor and a neurotoxicant. It is also a skin irritant and sensitiser. It is highly toxic to fish, aquatic invertebrates and honeybees and moderately toxic to birds, aquatic plants, algae and earthworms. |
