Trichlorfon is an organophosphate insecticide used to control cockroaches, crickets, silverfish, bedbugs, fleas, cattle grubs, flies, ticks, leafminers, and leaf-hoppers. It is applied to vegetable, fruit, and field crops
livestock
ornamental and forestry plantings
in agricultural premises and domestic settings
in greenhouses, and for control of parasites of fish in designated aquatic environments. It is also used for treating domestic animals for control of internal parasites [2,6]. Trichlorfon is available in dust, emulsifiable concentrate, granular, fly bait, and soluble powder formulations with percent active ingredient ranging from 40% (soluble powder) to 98% (technical). Trichlorfon is a selective insecticide, meaning that it kills selected insects, but spares many or most other organisms. Trichlorfon is toxic to target insects through direct applications and via ingestion.
