Grain discoloration

Symptoms

1. This occur at the time of panicle initation stage.

2. At this time normal grain color changes to brownish white color.

Management

1. Seed treatment with Bavistin (0.2%) or vitavax (0.2%) for 6 hrs.

2. Spary bavistin 0.1 %

Khaira disease

Symptom

1. Usually in nursery; chlorotic/ yellow patches at leaf base on both sides of the midrib; restricted root growth and usually main roots turn brown.

Management

1. Use 25kg Znso4/ha before transplanting or sowing at time of land preparation.

2. If crop is infected then use 5 kg Znso4 + 25 kg lime in 600-700 litre water per hectare.

False smut

Causal organism:- ustilago noidea virus

Symptom

1. False smut start as light green ball of spores covered by a thin silver colored skin. The balls erupt exposing the orange spores.

2. As time passes spores turn dark green to black. Damage from smuts occur due to contamination of other grains by spores during harvest, miiling causing quality problems and discoloration during paraboiling and cooking.

Management

1. Excessive nitrogen increases diseases.

2. Use resistant varities

3. At early stage of panicle initiation or at 50% flowering use mancozeb 0.25% or diethane M 45 ot copper oxychloride 25kg/ltr.

Sheath blight

Causal organism: Thanatephorus cucumeris

Symptoms

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

Management

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

Symptoms:

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

Management

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

Symptom:

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.

Management:

1. Seed treatment before sowing.

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

3. Use resistant varities.

BPH and WBPH

 

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.
