- Fenvalerate is an
insecticide. It is a mixture of four optical isomers which have
different insecticidal activities.
- The 2-S alpha (or SS)
configuration is the most insecticidally active isomer. Fenvalerate
consists of about 23% of this isomer.
- The technical grade is a
yellow-brown viscous liquid which may be partly crystallized at room
temperature, and has a specific odour.
- Fenvalerate is an
insecticide of moderate mammalian toxicity.
- Fenvalerate is most toxic to
bees and fish.
- It is found in some
emulsifiable concentrates, ULV, wettable powders, slow release
formulations, insecticidal fogs, and granules.
- Fenvalerate is a synthetic
pyrethroid with no cyclopropane ring in the molecule.
- Technical-grade fenvalerate
is 90-94% pure and consists of equal portions of the four stereoisomers
(RR, RS, SR, SS)
- It may be formulated as
emulsifiable concentrates, ultra-low volume concentrates, dusts or
wettable powders.
- Fenvalerate formulations
currently registered in the USA, Europe and India are emulsifiable
concentrates.
- Esfenvalerate is available
in the USA as a technical-grade product with a purity of 75%.
- It is formulated in the USA
as an emulsifiable concentrate.
- Fenvalerate is also
formulated in combination with oxydemeton-methyl.
- Fenvalerate can be prepared
by esterification of 3-phenoxybenzaldehyde cyanohydrin with 2-(
4-chlorophenyl)isovaleroyl chloride, or by condensation of
3-phenoxy-æ-halobenzyl cyanide with the isovaleric acid in the presence
of a base such as potassium carbonate.
- More conveniently,
fenvalerate can be provided by the Francis reaction using the
isovaleroyl chloride, the aldehyde and sodium cyanide.
- Fenvalerate is a highly
active contact insecticide that is effective against a wide range of
pests, including strains resistant to organochlorine, organophosphorus
and carbamate insecticides.
- It is used mainly in
agriculture, with about 90% used on cotton.
- It is also used on other
crops, such as vines, tomatoes, potatoes, pomes, other fruit and a wide
variety of other crops.
- It is also used in public
health and animal husbandry, e.g., for controlling flies in cattle
sheds.
- It is used in homes and
gardens for insect control and around the foundations of buildings to
control termites and carpenter ants.
- fenvalerate is relatively
immobile and readily degraded in soil, it is moderately persistent in
soils because of low water solubility and high octanol-water partition
coefficients.
- Also, fenvalerate has been
identified as having the potential to accumulate in aquatic sediments
and biota.
- Fenvalerate has undergone
laboratory and silo-scale field trials as a stored grain protectant in
Australia.
- Fenvalerate[4-Chloro-α-(1-methylethyl)benzeneaceticacid
cyano(3-phenoxyphenyl) methyl ester], a member of the family of
synthetic pyrethroid, type II, is commonly used as a highly active
insecticide in agricultural and other domestic applications in
China.
