Description
Fenamiphos is a colourless crystal or a tan, waxy solid. It is non-corrosive to metals and breaks down readily in strong acids and bases. Fenamiphos is used as a nematicide and an insecticide for use on a wide variety of field, vegetable, and fruit crops. Fenamiphos has been used primarily to control nematodes and thrips on various agricultural crops (i.e., citrus, grapes, peanuts, pineapples, tobacco, etc.) and non-agricultural (i.e., turf and ornamentals) sites.Alternatively, it can also be used for the treatment of other kinds of invertebrates such as sucking insects and spider mite. Fenamiphos takes effects through inhibiting the acetylcholinesterase in the pests. There are no residential uses for fenamiphos and is a Restricted Use Pesticide (RUP) due to high acute toxicity and toxicity to wildlife. Fenamiphos is a colorless crystalline substance. Solubility in water is
400 mg/L (20 ?C). It is soluble in polar organic solvents.
Log Kow = 3.3(20 ?C). It is stable in aqueous media; DT50
(22 ?C) at pH 4, 7, and 9 are 1, 8, and 3 yr.

Uses
Nematocide. Fenamiphos is primarily used to control nematodes in a wide
range of crops and in turf. It will also control mites and sucking insects in crops. Nematocide and insecticide. Systemic broad spectrum nematocide with anticholinesterase activity. Nematocide.
