2. Qualities of Aashirwaad
It acts as an insecticide with contact and
stomach action.
It disrupts the insect's central nervous
system by blocking the passage of
chloride ions through the GABA receptor,
an inhibitor of the central nervous system.
It also acts as Plant Growth Regulator,
which enhances the root growth and
results in higher yields.
Broad Spectrum insecticide.
Greater solubility in water than other
granules. Longer persistence.
Effectively controls insects resistant to
other insecticides.

Paddy, also called rice paddy,
small, level, ooded eld used
to cultivate rice in southern and
easternAsia.
3. What is Insecticides ?
Insecticides are agents of
chemical or biological origin
that control insects. Control
may result from killing the
insect or otherwise preventing
it from engaging in behaviours
deemeddestructive.
Insecticides may be natural
or manmade and are applied
to target pests in a myriad of
formulations and delivery
systems (sprays, baits,
slow-release diffusion,
etc.).
4. Crop
Paddy
Paddy is a cereal grain belongs to
the grass family of Graminae and
native to the deltas of the great
Asian rivers, the Ganges, the Chang
, and the Tigris and Euphrates. The
Paddy plant grows from 2 to 6 ft tall,
with a round, jointed stem, long
pointed leaves and edible seeds
borne in dense head on separate
stalks.
Paddy is one of the most
cultivated grain crops in India
as well as in Asian countries
and a staple diet of major part
of India. India is an important
centre for rice cultivation and
consumption. India stands in
second position after China in
theproductionofAce.
5. Target Pest
Stem Borer Stem borer (Scirpophaga) is a serious
paddy pest in India, Pakistan, Burma, Sri
Lanka, China, Japan Formosa,
Philippines and Indonesia. So, in all the
rice growing areas this insect or Moth
pest is available. This moth causes the
highest percentage of damage of the
paddyplant.
The larva of this moth feeds only the
internal tissue that the adult stage of
this insect (moth) never causes any
damage to the plant but only the
larval stage. This pest is commonly
known in English as stem borer
because the larva bores into the
stem.
6. Target Pest
The brown planthopper is a sucking
insect that, under heavy infestations, can
cause the wilting and complete drying of
rice plants, a condition known as
‘hopperburn’. The brown planthopper
also damages rice by transmitting
raggedstuntvirusandgrassystuntvirus.
The insect can complete as many as 12
generations in a single year in tropical
areas, where it resides year-round, and
fewer generations in temperate areas,
whereit is amigratorypest.
Planthoppers damages plants by
sucking sap from the mesophyll and
blocking the xylem and phloem by
laying egg masses in the midribs of
the leaf sheath and leaf blade.
Affected plants become chlorotic.
Older leaves turn progressively
yellow from the tip to the midpoint of
the leaf, then gradually dry up and
die. This feeding damage is
c o m m o n l y r e f e r r e d t o a s
hopperburn. Hopperburn begins in
patches but can spread rapidly as
the planthoppers move from dying
plantstoadjacentplants.

7. Target Pest
Leaf folder caterpillars fold a rice leaf
around themselves and attach the leaf
margins together with silk strands. They
feed inside the folded leaf creating
longitudinal white and transparent
streaksontheblade.
Rice leaffolders occur in all rice
environments and are more
abundant during the rainy seasons.
They are commonly found in shady
areas and areas where rice is
heavily fertilized. In tropical rice
areas, they are active year-round,
whereas in temperate countries they
areactivefromMaytoOctober.
Leaf folder
8. Target Pest
The xylem and phloem vessels are
plugged with their stylet sheath that
causes disruption in the transport of
food substances in the vessels.)
Mild infestation reduces the vigour
of the plant and the number of
reproductive tillers. Heavy
infestation causes withering and
complete drying of the crop. Plants
are predisposed to fungal and
bacterial infection through feeding
andovipositionalpunctures.
Affected plants become pale yellow
in colour and get stunted in growth. If
the plants are tapped large number
of leafhoppers may be seen jumping
to water. Both nymphs and adults
suck the plant sap from the leaf and
leaf sheath. (It is a phloem feeder.
Amino acid content is high in phloem
sapthanxylem.

9. Target Pest
The central shoot instead of producing
leaf produces a long tubular structure.
When the gall elongates as an external
symptom of damage, the insect will be in
pupal stage and ready for emergenc.The
maggot bores into the growing point of
the tiller and causes abnormal growth of
the leaf sheath, which becomes whitish
tubular and ends bluntly. It may be pale
green, pink or purplish. Further growth of
tiller is arrested.
This is called onion shoot, silver shoot or
anaikomban. The feeding by the maggot
and the larval secretion, which contains
an active substance called cecidogen, is
responsible for cell proliferation of the
meristematic cells and gall formation. It
is a pest in irrigated and wet season
crop. Tillers in 35 to 53 days old crops
arepreferred.
Rice Gall Midge
10. Target Pest
The rice whorl maggot Hydrellia spp. is a
pest of rice mainly In irrigated
ecosystem. It causes 20·30% yield loss
on the rst crop during April-September
but the infestation was less in the second
crop. The taxonomic characters and host

Whorl maggot is an important insect
pest causing serious damage to rice
crop during vegetative phase, direct
seeded rice have more risk than
transplanted rice. The pest attack
other crops also than the rice crop.
In India, as well as in Philippines the
occurrence recorded through out
