Phosalone is an organophosphate chemical commonly used as an insecticide and acaricide. It is developed by Rhône-Poulenc in France but EU eliminated it from pesticide registration on December 2006.

The median lethal dose of oral exposure in rat is 85 mg/kg and that of dermal is 390 mg/kg.[1]。It is weak acetylcholinesterase inhibitor.[2] It is taken by not only oral and inhalation but skin and it causes toxic symptoms peculiar to organophosphorus compounds such as miosis, hypersalivation, hyperhidrosis, chest pressure, pulmonary edema and fecal incontinence.[3] It is flammable and decomposes to toxic gases such as phosphorus oxides, sulfur oxides and nitrogen oxides.[2] It is harmful especially to water creatures.
