General Description
Yellowish oil. Used to control insects, mites, and nematodes. Not registered as a pesticide in the U.S.
Reactivity Profile
Organophosphates, such as Triazophos, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.
Health Hazard
This is an organophosphate pesticide. Triazophos is a cholinesterase inhibitor and acts on the central nervous system. Organic phosphorus insecticides are absorbed by the skin as well as by the respiratory and gastrointestinal tracts.
Fire Hazard
This is an organophosphate pesticide. Some of these materials may burn but none of them ignite readily. Container may explode in heat of fire. Fire may produce irritating or poisonous gases. Degraded by acids and alkalis.
Definition
ChEBI: Triazophos is an organic thiophosphate and an organothiophosphate insecticide. It has a role as an EC 3.1.1.7 (acetylcholinesterase) inhibitor, an acaricide, an agrochemical and a nematicide. It is functionally related to a 1-phenyl-1H-1,2,4-triazol-3-ol.
Agricultural Uses
Insecticide: Triazophos is a broad-spectrum insecticide and acaricide used to control sucking and chewing pests on a variety of crops, including cotton, rice, corn, beets and fruit
trees. Not currently registered for use in the U.S. Not approved for use in EU countries

Metabolic pathway
The main route of biotransformation of triazophos is degradation to 1-
pheny1-3-hydroxy-1,2,4-triazole, probably either via hydrolysis of triazophos
oxon or through oxidative cleavage of triazophos itself. The triazole
ring of this metabolite is opened to give 1-phenylsemicarbazide and semicarbazide,
both of which are conjugated in the rat and also degraded to
urea as the main urinary metabolite.
Degradation
Triazophos is stable to light but is hydrolysed by acids and alkalis (PM).
