Leaf folder


Scientific name : Cnaphalocrocis medinalis.

 Local name:

Damage of Leaf folder:

1. Larvae fold the leaves, remain inside the fold and scrape green tissues between the veins which makes the leaves white and papery.

2. Gradually the leaves dry up and the field presents a scorched appearance.

Control of Leaf folder:

At boot leaf stage one spray of monocrotophos 36EC @ 1.3 lit./ha or quinalphos 25 EC @ 2 lit./ha or phosphamidon 85 EC @ 0.6 lit./ha or cypermethrin 10EC @ 1lit./ha gives adequate protection of crop against the pest.


Green leaf hopper(GLH)


Scientific Name: Nephotettix virescens

Local name:

Damage of Green leaf hopper:

1. Nymph and adult suck cell sap and attract sooty mould.

2. Heavy infestation causes withering and complete drying of crop.

3. This pest is a potent vector transmitting several viral diseases like rice tungro diseases which cause yellowing, stunting and drying of plant.

Control of Green leaf hopper:

When pest population reaches 10 GLH/hill at vegetative stage or 20 GLH/hill at flowering stage, apply granular insecticide thiocyclam hydrogen oxalate (Evisect 5G) @ 40kg/ha.or spray MIPC(Mipcin 50WP) @ 1 lit./ha or monocrotophos (Monocil 40EC) @ 1.3lit/ha .


Rice bug/ Gundhi bug/ Ear head bug


Scientific Name : Leptocorisa acuta.

 Local Name :

Damage of Gundhi bug:

Sucking of grain sap by the bug causes ill-filled/ partially filled and chaffy grains and subsequent infection by fungi and bacteria results in grain discolouration.

Control of Gundhi bug:

When pest population is more than 5 bugs/m2 apply dust formulation of methyl parathion 5% or chlorpyriphos 5% @ 25 kg/ha.

At early milking stage apply monocrotophos 36EC@ 1.3 lit./ha or chlorpyriphos 20EC @2.5 lit./ha or oxydemeton methyl 20 EC @ 2.5 lit./ha but spraying at this stage is not advisable due to insecticide adsorption to the grain.


Rice hispa


Scientific name : Dicladispa armigera .

Local name :

Damage of Rice hispa:

Both adults and grub feed on the green matter of the leaves in short straight line parallel to mid rib.

The attacked leaves turn whitish and membranous.

Control of Rice hispa (RH):

i). Seedling root dip in chlorpyriphos 20EC @ 1ml in one lit. water for 12 h before planting protect the crop for 21 days in main field.

ii. When one adult or one damage leaf/hill at early transplanting and one adult or 1-2 damage leaf/hill at mid tillering stage is seen in the field apply quinalphos 25EC @ 2 lit./ha or monocrotophos 36 EC @ 1.3 lit./ha or phosphamidon 85EC@ 0.6 lit./ha or chlorpyriphos 20EC @ 2.5 lit./ha or carbofuran 3G @ 33 kg /ha.


White backed plant hopper(WBPH)


Scientific name : Sogatella furcifera .

Local name:

Damage of White backed plant hopper:

1. Both the nymphs and adults injure alike by sucking phloem sap leading to reduced vigor, stunting, yellowing, delayed tillering and grain formation. Their feeding attract sooty mould.

2. At severe infestation WBPH produces hopper burn in irregular shape as against circular patches caused by BPH in the field.

Control of White backed plant hopper:

When WBPH population reaches threshold level of 10 insect /hill apply chlorpyriphos20EC @ 2.5 lit./ha or monocrotophos 36EC @ 1.3 lit./ha or endosulphan 35EC @ 1.3lit./ha or Imidacloprid 200SL @ 0.5lit./ha or carbaryl 50WP @ 2.5 kg/ha , acephate 75SP @ 0.625kg /ha or carbofuran 3G@ 33 kg /ha


Brown plant hopper (BPH)

 Scientific name : Nilaparvata lugens.

  Local name:

Damage of Brown plant hopper:

This pest causes draining out of plant fluid and nutrients by continuous sucking during high infestation and plants become yellow and finally die.

This symptom of crop damage is known as hopper burn.

Control of Brown plant hopper:

 When insect population reaches at 10insect/hill apply monocrotophos 36EC @ 1.3 lit. /ha or chlorpyriphos 20EC@ 2.5 lit./ha or quinalphos 25EC @ 2 lit./ha or imidacloprid 200SL @ 0.5lit/ha as foliar spray with 500 lit. of water or carbofuran 3G @ 33 kg/ha


Asian rice gall midge


Scientific name : Orseolia oryzae

Local name:

Damage of Asian rice gall midge:

1. Infestation starts from nursery to panicle stage of the crop.

2. After hatching the maggots migrate to the growing meristematic tissue and feed on it, which in turn causes formation of gall called silver shoot/ onion shoot.

Control of Asian rice gall midge:

i. Seed immersion with cholrpyriphos 20EC@ 10 ml in one lit.

ii. water for 3 h or seed mixing with chlorpyriphos 20EC@ 3.75 lit./100 kg along with 10% solution of gum arabica or imidacloprid 200SL(20%) @ 0.25lit./100 kg.

iii. Seedling root dip in chlorpyriphos 20EC @ 1ml in one lit. water for 12 h. The exposure period can be reduced to 3 h if insecticide is mixed with 1% urea solution(10g urea in one lit. water).

iv. Granular application of carbofuran 3G @ 33 kg/ha or phorate 10G@ 10 kg /ha is also effective.


Yellow stem borer (YSB)


Scientific name: Scirpophaga incertulas Walker.

 Local name :

Identification of Damage Yellow stem borer:

1. The larvae bore into the leaf sheaths within 24 h of hatching and later enter the stem mostly the nodal region.

2. Larval feeding causes death of central shoot at vegetative stage, a condition known as dead heart and at the panicle bearing stage results in drying of the panicles and such panicles are called as white ear heads.

3. Damaged tillers/ panicles can be pulled out easily.

Control of Yellow stem borer:

i. Seedling root dip in chlorpyriphos 20EC @ 1ml in one lit. water for 12 h before transplanting.

ii. Apply granular insecticides carbofuran 3G @ 33 kg/ha or cartap 4G @ 25 kg/ha at a stage of one moth or one egg mass per sq meter or 5% dead heart.

iii. Apply spray formulations like quinalphos 25EC @ 2 lit/ha or monocrotophos 36EC @ 1.3lit/ha or chlorpyriphos 20EC @ 2.5 lit/ha with 500 lit. of water twice at a week interval coinciding with the peak emergence of moths.
