Introduction: Trasco
Super Mastan (Cypermethrin) is a synthetic
pyrethroid insecticide used to control
many pests, including moth pests of cotton,
fruit, and vegetable crops. Cypermethrin
is a very powerful and extremely active
insecticide of synthetic pyrethroid group.
It is recommended for the control of insects
which are not usually controlled by commonly
used insecticides. It acts both as contact
and stomach poison and it capable resistance
to ordinary insecticides. Cypermethrin
is most widely used in insecticide the
world over.
It is also used for crack, crevice,
and spot treatment to control insect pests
in stores, warehouses, industrial buildings,
houses, apartment buildings, greenhouses,
laboratories, and on ships, railcars,
buses, trucks, and aircraft. It may also
be used in non-food areas in schools,
nursing homes, hospitals, restaurants,
hotels, in food processing plants, and
as a barrier treatment insect repellent
for horses. Technical cypermethrin is
a mixture of eight different isomers,
each of which may have its own chemical
and biological properties. Cypermethrin
is light stable. It is available as an
emulsifiable concentrate.

Ecological Effects:
-
Effects
on birds: Cypermethrin is practically
non-toxic to birds. Its acute oral LD50
in mallard ducks is greater than 4640
mg/kg . The dietary LC50 in mallards
and bobwhite quail is greater than 20,000
ppm . No adverse reproductive effects
occurred in mallards or bobwhite quail
given 50 ppm, the highest dose tested
-
Effects
on aquatic organisms: Cypermethrin
is very highly toxic to fish and aquatic
invertebrates. The LC50 (96-hour) for
cypermethrin in rainbow trout is 0.0082
mg/L, and in bluegill sunfish is 0.0018
mg/L . Its acute LC50 in Daphnia magna,
a small freshwater crustacean, is 0.0002
mg/L. Cypermethrin is metabolized and
eliminated significantly more slowly
by fish than by mammals or birds, which
may explain this compound's higher toxicity
in fish compared to other organisms
. The half-lives for elimination of
several pyrethroids by trout are all
greater than 48 hours, while elimination
half-lives in birds and mammals range
from 6 to 12 hours . The bioconcentration
factor for cypermethrin in rainbow trout
was 1200 times the ambient water concentration,
indicating that there is a moderate
potential to accumulate in aquatic organisms
Elimination of half of the accumulated
amount of the compound took nearly eight
days. After 14 days 70 to 80% of the
material had been eliminated from the
organisms.
-
Effects
on other organisms: Cypermethrin
is highly toxic to bees
-
Breakdown
in soil and groundwater: Cypermethrin
has a moderate persistence in soils.
Under laboratory conditions, cypermethrin
degrades more rapidly on sandy clay
and sandy loam soils than on clay soils,
and more rapidly in soils low in organic
material . In aerobic conditions, its
soil half-life is 4 days to 8 weeks
. When applied to a sandy soil under
laboratory conditions, its half-life
was 2.5 weeks . Cypermethrin is more
persistent under anaerobic conditions.
It photodegrades rapidly with a half-life
of 8 to 16 days. Cypermethrin is also
subject to microbial degradation under
aerobic conditions . Cypermethrin is
not soluble in water and has a strong
tendency to adsorb to soil particles.
It is therefore unlikely to cause groundwater
contamination.
-
Breakdown
in water: In neutral or acid
aqueous solution, cypermethrin hydrolyzes
slowly, with hydrolysis being more rapid
at pH 9 (basic solution). Under normal
environmental temperatures and pH, cypermethrin
is stable to hydrolysis with a half-life
of greater than 50 days and to photodegradation
with a half-life of greater than 100
days . In pond waters and in laboratory
degradation studies, pyrethroid concentrations
decrease rapidly due to sorption to
sediment, suspended particles and plants.
Microbial degradation and photodegradation
also occur
-
Breakdown
in vegetation: When applied
to strawberry plants, 40% of the applied
cypermethrin remained after one day,
12% remained after three days, and 0.5%
remained after seven days, with a light
rain occurring on day 3. When cypermethrin
was applied to wheat, residues on the
wheat were 4 ppm immediately after spraying
and declined to 0.2 ppm 27 days later.
No cypermethrin was detected in the
grain. Similar residue loss patterns
have been observed on treated lettuce
and celery crops .
-
Appearance:
Pure isomers of cypermethrin form colorless
crystals. When mixed isomers are present,
cypermethrin is a viscous semi-solid
or a viscous, yellow liquid
