Uses and applications

What the substance is used for, by industry and function

Anthelmintics, Cholinesterase Inhibitors, Insecticides.

Insecticide, fumigant.

Dichlorvos as a "No Pest Strip" is used as an ectoparasiticide for small mammals. It is also used as a premise spray to keep fly populations controlled.

Dichlorvos is used as an agricultural insecticide on crops, stored products, and animals. It is also used as an insecticide for slow release on pest-strips for pest control in homes. Dichlorvos is used as an anthelmintic (worming agent) for dogs, swine, and horses, as a botacide (agent that kills fly larvae) for horses, and in flea collars for dogs. In 1995, EPA proposed cancellation of dichlorvos for all home uses, and for many commercial and industrial uses.

Pharmacology

Dichlorvos is a synthetic organophosphate acetylcholinesterase inhibitor and probable mutagen, neurotoxin, and reproduction toxicant that is used as a pesticide. It is characterized as a volatile pale-yellow clear liquid, and exposure occurs by inhalation, ingestion, or contact.

How it is made

Dichlorvos is produced by reacting trimethyl phosphate with chloral or by dehydrochlorination of trichlorfon in aqueous alkali.
