Form: Odorless crystals (pure); yellow-brown viscous semisolid at ambient temperatures (technical grade).Cypermethrin is a pyrethroid insecticide. It was first synthesized in 1974.
Cypermethrin is a synthetic chemical similar to the pyrethrins in pyrethrum extract (which comes from the chrysanthemum plant). Pyrethroids, including cypermethrin were designed to be effective longer than pyrethrins.

Viscous Semisolid??
Zeta-cypermethrin is used for the control of Lepidoptera, beetles and aphids in cotton, fruit, vegetables, field crops, ornamentals and forestry. It is also used in public health.??
ChEBI: A carboxylic ester resulting from the formal condensation between 3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylic acid and the alcoholic hydroxy group of hydroxy(3-phenoxyphenyl)acetonitrile.???
Insecticide: A U.S. EPA restricted Use Pesticide (RUP) used to control a variety of insects on cotton, fruit and vegetable crops. Also used in commercial and residential settings, ships, laboratories and food processing plants.???

Type II synthetic pyrethroid insecticide; an extremely potent, cell-permeable inhibitor of calcineurin.?? ?? ??
Pyrethroids, also called pyrethrinoids, are neurotoxic synthetic compounds used as insecticides, with irritant properties. Cypermethrin and fenvalerate have been reported as causing positive allergic patch tests, but only fenvalerate was relevant in an agricultural worker.??? ??
Pyrethroid insecticide used to control pests on cotton, fruit, and vegetable crops. Also used in commercial and residential settings, ships, laboratories, and food-processing plants. A United States Environmental Protection Agency Restricted Use Pesticide (RUP).????
Soil. The major soil metabolite was reported to be 3-phenoxybenzoic acid (Hartley and Kidd, 1987).The typical half-life of cypermethrin in the soil is 30 days, although it can range from two to eight weeks (6, 9). Soil microbes rapidly break down cypermethrin.
Cypermethrin has an extremely low potential to move in the soil. It is unlikely to contaminate groundwater because it binds tightly to soil particles. Cypermethrin is stable in sunlight.
The average half-life of cypermethrin on foliage is 5 days.

In cabbage plants, (1R)-cis- and (1R)-trans-isomers of cypermethrin undergo epimerization to (1S)-isomers, cis=trans isomerization, ester bond cleavage, hydroxylation of the phenoxy group in the alcohol moiety or the geminal methyl group in the acid moiety, hydration of the cyano group to an amido group with subsequent hydrolysis to the carboxylic acid, and the conjugation of the carboxylic acid, and alcohols with sugars.?? ??

May react violently with strong oxidi- zers, bromine, 90% hydrogen peroxide, phosphorus trichloride, silver powders, or dust. Incompatible with silver compounds. Mixture with some silver compounds forms explosive salts of silver oxalate.??? ??
Incineration would be an effective disposal procedure where permitted. If an efficient incinerator is not available, the product should be mixed with large amounts of combustible material and contact with the smoke should be avoided. In accordance with 40 CFR 165, follow recommendations for the disposal of pes- ticides and pesticide containers.????? ?? ?? ? ???
