Description
Pale straw-colored liquid; [Merck Index]
Sources/Uses
Used as insecticide to protect livestock (external use); [Merck Index]
Comments
A cholinesterase inhibitor; [Merck Index] No adverse effects to growth or histopathological changes were observed in 90 day feeding study with rats (males at 900 mg/kg diet and females 300 mg/kg diet); Cholinesterase inhibitor; [HSDB] “The average of two baseline respective cholinesterase activity determinations three days apart, with no exposures to enzyme inhibiting pesticides for at least 30 days, is recommended for each worker prior to exposure to cholinesterase inhibitors because of large inter-individual differences in published baseline values. To be established at least once a year. Removal from workplace exposures is recommended until the cholinesterase activity returns to within 20% of baseline.” [TLVs and BEIs]
Restricted
Cancelled--no longer registered as a pesticide for use in the US; [HSDB]
