Sheath blight

Causal organism: Thanatephorus cucumeris


1. initial infection occur on the stem near the water lime and appear as water soaked oval lesion which often dries and turns tan.

2. All the plant parts are susceptible to infection except roots. Sheath tends to develop in circular areas in the field and cause what are called bird nests.

3. It starts as white bean like structures that turn dark brown to black


1. Fungiside applications are typically applied from panicle differentiation to heading . the boot 2-4 inch in the flag leaf sheath is effective timing.

2. Avoid excessive plant stands.

3. Donot over fertilize with the nitrogen.

4. Avoid late planting


Army worm


Local name:

Nature Of Damage of Armyworm:

1. Damage is caused by larvae feeding on leaves from edges, leaving only the midrib and stems.

2. In severe infestation, entire seed beds and fields are destroyed and appears r as if it has been grazed by animals.

Control of Armyworm:

1. Armyworms are held in check by egg and larval parasites. When these parasites fail, usually because of drought, armyworms become epidemic.

2. Parasitoids such as Trichogrammatids, Scelionids, tachinids, ichneumonids, eulophids, chalcids, and braconid wasps parasitize this pest.

3. Ants, birds and toads feed on the pest. Fungal diseases and a nuclear polyhedrosis virus also infect the larvae.


Rice hispa


Local name :

Symptoms for damage of Rice Hispa:

1. Damage is caused by both grubs and adults. Grubs feed by tunneling lower and upper epidermis, resulting in regular translucent white patches.

2. Adults scrap the surface of leaf blade often leaving only the lower epidermis.

3. Damaged plant parts appear as white streaks parallel to mid rib.

Control of Rice Hispa:

1. Spray quinalphos 25EC @ 2000 ml ha-1 or monocrotophos 36 WSC @ 850 ml ha-1 or chlorpyriphos 20 EC @ 1500 ml ha-1 or triazophos 40 EC @ 400 ml ha-1 or Ethofenprox 10 EC @ 450 ml ha-1or Fipronil 5 SC @ 600 ml ha-1 or 2. Apply carbofuran 3G @ 25 kg ha-1.t


Brown spot

Causal organism: Helminthosporium oryzae


1. Many dark brown elliptical spots on leaves; infects coleoptiles of seedling and causes blightining; infected kernel shriveled.


1. Seed treatment before sowing with carbandazim (2.5g/kg).

2. Treatment with fungicide like mancozeb 0.25% or Adinophos 0.1%.

3. Spray hinosan 0.1%in 12 -15 days interval for 3-4 times in standing crop or spray blitox 50 @0.3%.

4. Use resistant varities like Indira Sugandhit Dhan-1.

5. Well leveled the land and use balanced fertilizer soil.


Leaf Roller


Local name :

Nature and symptoms for damage of leaf folder:

1. Larvae infest the young leaves.

2. They feed on leaf tissue and as they become older, fold the leaf to form a tube.

3. During severe infestation, leaf margins dry completely.

Control of Leaf Folder

1. Spray cartap 50 WP @ 600 g ha-1 or monocrotophos 36 WSC @ 850 ml ha-1or chlorpyriphos 20 EC @ 1500 ml ha-1or quinalphos 25 EC @ 2000 ml ha-1. Spraying should be done only when there are 3 freshly damaged leaves per hill.

2. Severe infestation particularly to flag leaf affects grain filling resulting in yield loss.


Sheath rot

Causal organism- Magnoporthe Salvinii


1. Disease infect rice after tillering.

2. The initial infection occurs on the stem in the leaf sheath and towards maturity penetrating in to the culm often causing lodging.

3. Below sheath small dark brown spots formed which have no shape. Because of this diseases panicle do not emerges

4. If the panicle emerges grains do not fill and cause yield loss.


1. Seed treatment before sowing.

2. Use fungiside like adinophos or Hexaconazol (0.1%) or Mancozeb (0.3%) .

3. Use resistant varities.




Local name: Bhura mahu

Nature of Damage of BPH and WBPH :

1. Nymphs and adults damage the plants by sucking the sap and by plugging xylem and phloem with their feeding.

2. Sheath and pieces of tissues are pushed into these vessels during exploratory feeding and affects early stage of plant growth, reduces height and general vigour.

3. As a result the infested plant turns yellow and dies.

4. At later stages, crop dies and the patches are called "hopper burn". BPH also transmits "grassy stunt virus".

Management of WBPH

Seedling stage: 33 kg Carbofuron 3G/ 10 kg phorate 10G.

Tillering stage: 75 ml Emidicloprid/ 600 ml fipronil 5%.

Management of BPH

Tillering stage: 900 g Carboryl 50% / 850 ml monocrotophos 36%.

Booting stage: 1100 ml monocrotophos 36%/ 100 ml Emidicloprid 20%.

Panicle initiation stage: 1500 ml monocrotophos 36%/ 125 ml Emidicloprid.


Bacterial leaf blight (BLB)

Symptom of Bacterial leaf blight

1. ‘Kresk’ occurs in early stage (plant withers and dries up), in later stage blightining starts from the tip of the leaves to the base, straw turned yellow, partially filled grains.


1. Use balanced fertilizer dose.

2. Drain out excess of water.

3. Use resistant varities like Sawa masuri, Bambleshwari.


Whorl maggot

 Nature of Damage of Whorl maggot :

1. Yellow spots, transparent streaks and pin holes are the other symptoms found on leaves. Neonate maggots feed on the unopened central leaves.

2. Under severe infestation many broken or bent leaves willappear resulting in poor growth and reduced tillering.

Management of Whorl maggot:

• Application of carbofuron granules in the nursery 5-7 days before pulling of seedlings will protect the crop until 20DAT.

• If severe infestation is observed after 25 DAT spray monocrotophos 36 WSC @ 850 ml ha-1 or chlorpyriphos 20 EC @ 1500 ml ha-1.

 • High volume or low volume sprayers can be used to apply the insecticides.


Rice Stem Borer


Local name: Tanachedak  

Nature of Damage of Stem Borer :

1. Caterpillars bore into stem and feed internally causing death of central shoot"dead hearts" in vegetative stage and "white earhead" at milky stage respectively.

2. The larvae of the borers enter the tiller, feed, grow and cause the characteristic symptoms of ‘dead hearts’ or ‘white ears’ depending on the crop stage.

3. At tillering stage, the feeding frequently results in severing the apical parts of the plant from the base.

4. The central leaf whorl does not unfold, turns brownish and dries out although the lower leaves remain green and healthy. This condition is known as ‘dead heart’. Affected tillers dry out without bearing panicles.

Management of stem borer:

At seedling stage seedling: 33 kg Carbofuron 3G/ 10 kg phorate 10G.

At tillering stage: 25 kg cartap 4G/ 25 kg fipronil 0.3G.

Booting Stage: 1100 ml monocrotophos 36% / 2000 ml chlorpyriphos 20%.

Panicle emergence : 1500 ml monocrotophos 36% / 2500 ml chlorpyriphos 20%.
