Neem oil has proven to control about 600
types of insect species effectively. Thus
it plays a fundamental role in the pest
management. Agricultural trend of using
synthetic products for control of pests
have been revolutionized by Neem oil, especially
due to its proficient characteristics as
a pest repellent and a supplement for the
plants as well. But for consideration, the
key of neem oil is pest control, which is
the obvious reason to increase the productivity
in farms on its application. Moreover, different
crop invites different insects and application
of certain pesticide for particular pest
will serve as an advantage for the others,
and they are likely to develop resistance
against the pesticide
which makes the condition even worse. However,
neem oil cannot be resisted by any insects
in common due to the presence of an active
constituent of neem called Azadirachtin,
a tetranortriterpenoid complex structure
similar to insect hormone that drags the
insects to feed and terminates it. Thus
it is sure of repelling most of the pests
that are considered to be destructive in
nature. The list of some of those destructive
insects in farms includes:
American bollworm, Aphids, Berry borers,
Black aphids, Black headed caterpillar,
Brown plant hopper, Castor semi looper,
Coffee stem borers, Cut worms, Diamond Black
Moth, Ear Head bug, Early shoot borer, Eriophyid
mite, Flea beetles, Flush worms, Fruit borer,
Fruit borer, Fruit flies, Gall midge, Hairy
Caterpillar, Helicoverpa moth, Inflorescence
caterpillars, Japanese
beetles, Jassids, Jumping lice, Leaf
hoppers, Leaf miners, Leaf
Webbers, Leafhoppers, Mealy bugs, Pigeon
pea cyst Nematode, Pink bollworm, Pod borer,
Pod bug,
Poilu Beetles, Prodenia, Pulse Beetle, Red
flour beetle, Red palm weevil, Rhinoceros
beetles, Rhizome borers, Rice Hispa, Scale,
Shoot borer, Shoot borers, Shoot fly, Spider
mites, Spodoptera litura moth, Spot mites,
Spotted boll worm, Tea mosquito bug, Thrips,
Tobacco caterpillar, Top borer, White Grubs,
Whiteflies.
These insects can be cured using a common
neem
oil spray. Neem oil concentration in
the spray differs for each insect but in
most of the cases the mild concentration
of pure neem oil (certified by EPA) is advised
for use. Spraying neem oil in the field
eradicates the populated insects at the
site and resists further invasion of the
insect into the field as well. The treatment
of neem oil spray needs to be done once
or twice in a week to effective control
the plants from pests.
