Fenitrothion in 1959 brought by Sumitomo Chemical Company and Bayer AG to market. Fenitrothion is less toxic than parathion in a similar spectrum of activity and a so -like structure so that it can be produced in the same equipment. Fenitrothion is used as an effective and widely used insecticide and selective acaricide contact.

Properties

Fenitrothion is an oily, yellowish liquid with a characteristic odor. It belongs to the group of chemically Thiophosphoric.

Regulation

Europe

The application of fenitrothion is banned in the EU. The Permitted daily dose is 0.005 and Acute Reference Dose 0.013 milligrams per kilogram of body weight per day.

In Switzerland, it was included as an active ingredient in two drugs that have been used against various insect pests, aphids and mites in fruit orchards and vineyards. The approval of these preparations has now been withdrawn.

Safety

Fenitrothion is a contact poison, which, like all organophosphates acts as a neurotoxin in humans.

In the studies conducted so far there was no evidence of a teratogenic or reproductive toxicity. Also, mutagenic or carcinogenic effects were not detected.
