Documented Uses

• Used as insecticide and acaricide for cereals, cotton, orchard fruits, rice, vegetables, forestry, turf, greenhouses, animal houses, public health, and stored products; [HSDB] Used in Australia on stored wheat; Only registered in the US for use in ant and roach bait containers; [Reference #1]
• There are no registered food uses in the U.S. Fenitrothion is used in Australia on stored wheat and there is a U.S. tolerance for imported wheat gluten. Residential: The only registered use in the U.S. is for containerized ant and roach baits in child resistant packaging.
• For use on cereals, cotton, forests, fruit, rice, and vegetables. Fly and mosquito sprays for farms. ... for locust and grasshopper. /Not registered for food use in the USA/
• Preparation: Belgium patent 594669 (1960 to Sumitomo); Belgium patent 596091 (1960 to Bayer).
• PRODUCED BY REACTION OF O,O-DIMETHYL PHOSPHOROCHLORIDOTHIOATE WITH ALKALI METAL SALT OF 3-METHYL-4-NITROPHENOL.
• Technical grade fenitrothion contains the S-methyl tautomer, which is formed from fenitrothion in varying amounts in presence of heat. This compound, which is much more toxic than the O-methyl compound, occurs in fenitrothion in concentrations ranging from 0.4 to 4%.
