Quinalphos is an insecticide and acaricide with contact and
stomach action. By penetrating the plant tissues through
translaminar action exhibits a systemic effect. It is broad spectrum
insecticide and acaricide used against a range of common insect
pests. It is contact and stomach poisonous emulsiable concentrate
formulation.It is used for control of many insect pests of the orders
Lepidoptera, Coleoptera, Diptera,Hemiptera etc. It has good
initial and residual toxicity against stem borer, leaf roller, brown
plant hopper, hispa on paddy.

Paddy is susceptible to a wide
range of insect pests. Among
the most destructive are the
Brown plant hopper, hispa, leaf
roller, Stem borer and Blue
Beetle.
Rice Pests
Farmers lose an estimated average of 47% of
their rice crop to pests and diseases every year.

planthoppers cause leaves to
initially turn orange-yellow
before becoming brown and
dry and this is a condition called
hopper burn that kills the plant.
BPH can also transmit Rice
Ragged Stunt and Rice Grassy
Stunt diseases. Neither disease
can be cured. Planthoppers can
be a problem in rainfed and in
i r r i g a t e d w e t l a n d
environments. It also occurs in
a r e a s w i t h c o n t i n u o u s
submerged conditions in the
eld, high shade, and humidity.
Leaf roller 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 streaks on the
blade. Heavy use of fertilizer
e n c o u r a g e s r a p i d
multiplication of the insect.
High humidity and shady areas
of the eld, as well as the
presence of grassy weeds from
rice elds and surrounding
borders favor the development
of the pest.
Stem borers can destroy rice at
any stage of the plant from
seedling to maturity. They feed
upon tillers and causes dead
hearts or drying of the central
tiller, during vegetative stage;
and causes whiteheads at
reproductive stage. The stem
borer larvae bore at the base
of the plants during the
vegetative stage. On older
plants, they bore through the
upper nodes and feed toward
the base.
This pest occasionally causes
damage to the paddy. It has an
all India distribution and infests
the paddy crop along with Rice
Hispa. Locally it is called as”
Dhan Ka Nila Bhaunra”. The
adults are small, metallic blue
beetles with a series of black
dots on the elytra.The grubs are
surface feeders and they scrap
the green matters of the
leaves. The adult also, feed
upon the leaves but the serious
damage is caused only by the
grubs.
Rice hispa scrapes the upper
surface of leaf blades leaving
only the lower epidermis. It also
tunnels through the leaf tissues.
When damage is severe, plants
become less vigorous. The
presence of grassy weeds in
and near rice elds as alternate
hosts harbor and encourage
the pest to develop. Heavily
fertilized eld also encourages
the damage.

Pod borer is a notorious pest of Red
grams causing heavy damage to the
crop. Yield loss due to pod borer
damage can be quite high. The larvae
feed on the buds and flowers and bore
into the pod to eat the developing seeds.
The flowers and pods are bound
together by a frass-covered web,
produced by the larvae. Seeds within
damaged pods are totally or partially
eaten bybean pod borerlarvae.
The maggot feeds on the developing
grain.The infested pods do not showany
external evidence of damage until the
fully grow larvae chew holes in the pod
walls. These bore the grains and make
the tunnel in them. This hole provides an
emergence "window" through which the
adults exit the pod.Damaged grains do
not mature and due to excreta fungus
may develop in the grain. The infested
grains loose theirviability

Cardamom
In the culinary arts, cardamom is a spice
made from the seed pods of various plants in
the ginger family. Cardamom has a strong,
pungent flavor and aroma, with hints of
lemon, mint, and smoke. Cardamom pods
contain a number of seeds, but the entire
cardamom pod can be usedwhole orground.

Thrips lacerate the surface tissues of capsules and suck the exuding sap. The injured tissues form a
corky layer on the capsule surface which appear as scales. Such capsules appear stunted, malformed
and shrivelled with gaping slits on the skin. The condition is popularly known as “cardamom itch”. Seeds
from infected capsules give poor germination. At panicle formation stage, infestation causes stunting of
panicles and shedding of owers. Scrapping of capsules lower their quality and quantity to the extent of
even 80-90%

Chilli is an important vegetable cum
spice crop grown in almost all parts of
tropical and subtropical regions of the
world. It belongs to the family
Solanaceae. Chilli has many culinary
advantages.Itcomprisesnumerous

fatty oils, capsaicinoids, carotenoids,
vitamins, proteins, fibres and mineral
elements. Capsicum fruits mayserve as a

11. Mites
Aphids
More than 293 insects and mite
species attack the crop in field as
well as storage. Amongst these, the
thrips, Scirtothrips dorsalis and
yellow mite, Polyphagotarsonemus
latus are the most important. Yellow
Mites can be a big problem, for chilli
growers. They are tiny and can be
hard to spot, but in large numbers
causeseriousdamage.
Adult are small succulent, pear-
shaped soft bodied insects with
prominent reddish eyes and
cornicles at dorsal surface of the
abdomen that vary in color from
yellowtogreentoblack.

12. Jute
Jute is an edible leafy vegetable which is a member of genus Corchorus
classied under the subfamily Grewioideae of the family Malvaceae. It is
widely found in tropical and subtropical areas from Asia to Africa
appreciated as food and for its strong ber. Jute bres are long , lustrous ,
resilient and softer to touch . It has a natural colour in light tan to brown
range and its ber can be bleached and can be dyed well. India is the
world’s largest producer of raw jute and jute goods , contributing to over
50 percent and 40 percent respectively of global production.

13. The pest passes winter in soil in the pupal stage and the moths appear in May -
June, when the crop begins to grow in the eld. The attack is severe on half-grown
plants which are one metre high. They camouage but are easily noticed when they
crawl by producing a loop in the middle. The second generation is the most
damaging and sometimes up to 90 per cent of the leaves may be eaten up.
Generally, the top 7-9 leaves are damaged and plant growth is adversely
affected, resulting in a considerable reduction in the yield of bre.
Yellow mite is one of the major pests of jute crops. Yellow mite injuries to the
number of leaves, leaf area, fresh leaf weight, dry leaf weight, soluble solids,
plant height, base diameter, ber weight, stick weight, number of owers per
plant, number of pods, pod weight per plant, seeds per pod, seed weight and
1000 seeds' weight of plants infested at three different phenological stages.
Leaves folded longitudinally and larvae remain inside. Larvae scrape the green
tissues of the leaves and become white and dry. During severe infestation the
whole eld exhibits whitish scorched appearance. The leaves of the jute plant are
seen folded, rolled and often webbed together with white patches on them
indicating the areas fed by caterpillar. When such folded leaves are opened up,
larvae can be seen.
