Industrial and agricultural sectors had inaviability increased the level
of heavy metals, pesticides in natural waters among which pesticides
play a major role among pollutants of aquatic environment. When we
take spotlight on the impact of pesticides some pyrethroid causes
hazardous impact on fishes, many aquaculture researchers had made
research on impact of pyrthoid in various terms. Most of the work had
been carried out outside India and least attempts had been carried out
in India. Pyrethroid insecticides are used on a worldwide scale. It has
been calculated that pyrethroids accounted for 25% of the insecticide
market in the industrial countries in the 90s. Pyrethroids are the most
common insecticides for both indoor and agricultural purposes. Their
chief advantages are high insecticidal potency and low mammalian
toxicity with rapid metabolism and lack of terrestrial accumulation.

Introduction
Cypermethrin is a synthetic, pyrethroid insecticide that has high insecticidal activity, low avian
and mammalian toxicity, and adequate stability in air and light (Kaufman et al., 1981). It is used
to control many pests including lepidopterous pests of cotton, fruit and vegetable crops and is
available as an emulsifiable concentrate or wettable powder. According to the label for
Ammo®2.5 EC insecticide, which contains 2.5 pounds of cypermethrin per gallon, the product
should not be applied directly to water or to areas where surface water is present. Also,
cypermethrin should not be applied when wind may cause drift beyond the intended treatment
area. Due to its extreme toxicity to fish and aquatic organisms, Ammo®2.5 EC is registered as a
“restricted use pesticide”, and is for sale to, and to be used only by, Certified Applicators.
The environmental fate of cypermethrin [(±)-Alpha-Cyano-(3- phyenoxyphenyl) methyl
(±) - cis/trans – 3 - (2, 2 - dichlorovinyl) -2, 2 dimethylcyclopropane carboxylate.] cypermethrin is
a synthetic, pyrethroid insecticide that is available in several formulations as an emulsifiable
concerntrate or wettable powder. The following diagram shows as per methrin degradation.
