Malathion (Ref: OMS 1) |
Last updated: 21/08/2024 |
(Also known as: carbophos; maldison; mercaptothion; carbofos; ENT 17034) |
SUMMARY |
Malathion is a broad-spectrum insecticide. It is moderately soluble in water and readily soluble in many organic solvents. It is quite volatile and has a low potential for leaching to groundwater. Malathion is not usually persistent in soil or water systems. It is moderately toxic to mammals, a cholineserase inhibitor and a neurotoxin. Malathion is highly toxic to honeybees and aquatic species with the exception of algae. It is moderately toxic to birds and earthworms. |
