Insecticides are used to terminate insects
of course, but the efficiency of an insecticide
depends upon its source, which means, whether
it is derived from nature or prepared synthetically
using certain formulas. In case of artificial
method, lots of variations in the ingredients
and their concentration were worked in the
laboratory giving rise to different types
of insecticides. Basically, insecticides
are categorized into three main types, namely:
- Systemic or Universal insecticides
- Contact type of insecticides and
- Ingested or digestive type of insecticides
Systemic or universal type of insecticides
is used to develop insect resistive character
in plants by their application through the
soil medium. The active ingredients present
in the product are absorbed by the plant
from the soil and by their intrinsic cycle
the parts of the plant acquire the resistant
and toxicity against insects. The effect
of this insecticide remains for days that
help in reducing frequent spraying of insecticide
in fields.
Contact type of insecticide is an instant
killing insecticide that can be used in
place where the insects need to get rid
off in short period of time. This type of
insecticide can terminate
insects at the time of its application rather
than defending after its course. General
household insecticides come under this type.
Some insecticides reveal the effect after
its ingestion by organism. This refers to
ingested type of insecticides. This may
be of solid form and are mainly used to
kill pests like rats and roaches. These
are available in the market along with the
directions that makes easy in handling and
does not require any skill unlike the use
of other insecticides.
How Neem oil differs?
Firstly, Neem
oil is an organic insecticide means
it does not affect the environment on its
use. Azadirachtin, an active constituent
of neem that depicts its insecticidal property
has been the key for the EPA to evaluate
Neem as one of the best among natural insecticides.
Moreover, the above mentioned types of insecticides
and their characteristics were all observed
in one, neem oil.
Neem oil can be used,
- In soil to repel ground insects and
pests,
- In the form of cakes
for controlling rats and roaches.
- In areas of the insect breeding for
complete eradication.
Even EPA advises farmers of US to use
certified Neem oil for effective control
of insects. Comparatively, the cost of neem
oil is also less.
