Agent Name Imiprothrin
CAS Number 72963-72-5
Formula C17-H22-N2-O4
Major Category Pesticides
Synonyms Pralle; Pralle T; Cyclopropanecarboxylic acid, 2,2-dimethyl-3-(2-methyl-1-
propenyl)-, (2,5-dioxo-3-(2-propynyl)-1-imidazolidinyl)methyl ester; [ChemIDplus]
Category Pyrethrins/Pyrethroids
Description Viscous brown liquids or solids; [EXTOXNET]
Sources/Uses Pyrethrins are insecticides used mainly in households; Also used to kill insects on pets and in grain storage bins and poultry pens. Dusts containing 0.3% to 0.5% pyrethrins are used on crops. [EXTOXNET]
Comments Pyrethroids have low toxicity to humans after dermal exposure. Of 573 dermal or ingestion poisoning cases in China, 51 patients had disturbed consciousness and 34 had seizures. Of those, only five were occupationally exposed. Seizures are more commonly related to exposures to fenvalerate, flucythrinate, cypermethrin, deltapermethrin, and fluvalinate. Seizures have not been reported after exposure to permethrin. Pyrethroids may also cause paresthesias after skin contact. Paresthesias (stinging and numbness) usually begin 1-2 hours after contact and resolve within 24 hours. [EPA Pesticides, p. 87-8] Pyrethrins cause liver injury when fed to animals at high doses.
