Category

Carbamate Insecticides

Description

White to tan, crystalline powder with a faint, characteristic odor. [insecticide]; [NIOSH]

Sources/Uses

Used to control ants, cockroaches, crickets, flies, mosquitoes, and crop insects; [EXTOXNET]

Comments

Classified as "highly toxic" with an LD50 of approximately 100 mg/kg in rats and mice, propoxur has a field half-life of 14 to 50 days. [EXTOXNET] "The animal and human studies demonstrated consistent NOAELs in the range of 3 mg/m3 to 18.7 mg/m3, thus a TLV-TWA of 0.5 mg/m3 is recommended to be sufficiently protective." [ACGIH]
