| Description |
Colorless liquid with a faint ester-like odor. [insecticide]; [NIOSH] |
|---|
| Sources/Uses |
Exterminators use a 85-90% concentration, while the liquid or granules used for house and garden contains 1-5% diazinon. [ATSDR ToxFAQs] |
|---|
| Comments |
In animals, diazinon has a half-life of about 12 hours. Cows completely eliminate diazinon within two weeks of the last exposure. [http://ace.orst.edu/info/nptn] Classified as mildly or moderately toxic depending upon the formulation; [EXTOXNET] Diazinon causes hepatic steatosis in high-dose feeding studies of rats. [Zimmerman, p. 394] |

| Restricted |
Use on sod farms and golf courses cancelled by EPA in 1988; [EXTOXNET] |
