Rice root weevil

This weevil is a localized pest in the rice area around Rajpura. However this pest has also been observed in some other areas in the state.Its white ,legless grubsfeed on roots in the soil from July to September.The attacked plants turn yellow , stunted and produce only a few tillers .

Control : Apply any of the following granular pesticides in standing water: 3kg of Thimet/Foratox 10G(phorate) per acre
 வேளாண்மை உதவி இயக்குநர் ராஜசேகர் விவசாயிகளுக்கு வெளியிட்டுள்ள அறிக்கையில் கூறி இருப்பதாவது நெல்லை மாவட்டம் கடையம் வட்டாரத்தில் பரவலாக நடவு செய்யப்பட்டுள்ள நெற்பயிரில் இலைச்சுருட்டுப்புழுக்களின் தாக்குதல் அதிகமாக காணப்படும். பெத்தான்பிள்ளைகுடியிருப்பு, சம்பன்குளம், ஆம்பூர் பகுதிகளில் சாகுபடி செய்துள்ள சாவித்திரி நெல் பயிரில் இலைசுருட்டுப்புழு தாக்குதல் அதிகம் காணப்படுகிறது.
இப்பூச்சிகள் பெரும்பாலும் இரவு நேரங்களில் காணப்படுகிறது. மழை குறைவாகவும், மேகமூட்டமாக இருக்கும் சூழலில் இவற்றின் தாக்குதல் அதிகமாக இருக்கும். தாய் அந்துப் பூச்சிகள் வெளிரிய பழுப்பு நிறத்தில் பளபளக்கும் மஞ்சள் கலந்த பழுப்பு நிற இறக்கையுடன் காணப்படும்.

Rice Hispa

Rice Hispa

Symptoms of damage:

1. The adult beetles feed on the epidermal tissue of the leaves and the grubs mine the leaf tissue and pupate there.

2. The beetles scrape the chlorophyll between the veins of the lamina resulting in whitish parallel streaks. Later, owing to indiscriminate feeding even on leaf veins, white blotches appear on leaves.

3. In severe epidemics leaves dry up and the crop presents a scorched appearance.

Control Measures:

1. Drain out the field.

2. For chemical control apply Endosulfan 35 E.C. @ 1.25 lit./ha or Quinolphos 25 E.C. @ 1.25 lit./ha or Phosphymidon 85 E.C.@ 300 ml/ha.

Brown & Green Hopper

Brown & Green Hopper

Symptoms of damage:

1. The leafhoppers attack all the stages of the plant. Both adults and nymphs cause direct damage by sucking plant sap leading to stunted growth and reduced tillering.

2. At high population levels their feeding results in the drying of the plants and the infested paddy fields appear blighted. Infestation at the time of panicle emergence affects grain formation.

3. Apart from direct damage the insect is also a carrier of tungro disease causing virus.

Control Measures:

1. To control both types of hopper apply Furadon 3G granules @ 30 Kg per hectare or Thimate 10 % @ 10 Kg/ha or Dimecron 100E.C. @ 0.5 ml in one litre of water or Rogor 30 E.C. @ 1.75 ml in one litre of water.

Gallmidge Fly (Sarha insects)

Gallmidge Fly (Sarha insects)

Symptoms of Damage:

1. The chief stage of Gall midge which causes damage is the maggot. The maggot feeds on the growing tip and suppresses the leaf primordial differentiation.

2. This in turn induces the development of radial ridges from the innermost leaf primordium followed by an elongation of the leaf sheath.

3. A hallow chamber called the ‘Gall’ forms around the larva. As the larva feeds, the Gall enlarges at the base and elongates having the appearance of an onion leaf or silver shoot

4. There are 3 larval instars. Generally one maggot is found in a tiller.

5. Galls appear within a week after the larvae reach the growing point.

6. In some cases there would be no gall development but necrosis of the growing tip is noticed. Profuse tillering is positively correlated with the silver shoots.

Control Measures

(1) To control Gallmidge Fly grow resistant rice varieties like I.R. 36 and Rajendra Dhan 202.

(2) Dip the root of the seedling before transplanting in solution of Chlorpyriphos 20 E.C. @ 0.02 % + 4 % urea (0.5 lit. Chlorpyriphos in 25 lit. of water) for 3-4 hours.

(3) Where Gallmidge is a serious problem in every year, apply Carbofuron 3G @16 Kg or Forate 10G @ 5Kg or Quinolphos 5G @ 10 Kg per hectare after 15-20 days of transplanting. Repeat the same insecticide after 40 days of transplanting. During application of the insecticide 6-7 cm standing water for 3-4 days in the field is essential.

(4) Spray liquid insecticides like Monocrotofos 36 E.C.@ 1000 ml/ha or Fenthion 100 E.C. @ 500 ml/ha or Fosalon 35 E.C. @ 1500 ml/ha.

(5) Apply 5 % Neem oil to control Gallmidge.

Rice Gundhi Bug

Rice Gundhi Bug

Symptoms of damage:

1. The adults and nymphs suck the juice from the developing grains in the early stage of grain formation.

2. Young succulent leaves and shoots are also attacked before the grain formation stage. Infestation is characterised by the presence of some empty or ill-formed grains in the panicles.

3. A hole is left on the grain at the point of puncture and around that hole a brownish spot develops causing discoloration of the panicles.

Control Measures: To control the Rice Gandhi Bug broadcast Endosulfan 4 per cent dust or Quinolphos 1.5 per cent dust @ 10 Kg/acre.

Juice sucking insects

Juice sucking insects

Symptoms of damage:

1. Both the nymphs and adults suck the sap from leaves. As a result of pest attack, initially yellowish streaks appear on the leaves.

2. Later, the leaves curl longitudinally from the margins inwards leading to sharply pointed leaf tips resembling that of needles, which finally wither.

3. In severely infested areas, the plants become lanky and present a sickly appearance. Infestation at the panicle stage causes unfilled grains or sterility.

Control Measures:

1. To control the insects like Madhua , Dhahiya insects and Thrips apply granular insecticides like Carbofuron, Forate, Quinolphos etc.

2. Beside these, farmers can spray Phosphymidon @ 4-5 ml/10 lit.of water or Monocrotophos @ 10 ml/10lit. of water or Methyl Dymeton (Metasystox) 1 ml/lit. of water.

3. Grow resistant rice varieties like Kanak, Satyam, Kishori and Satyam to control the insects like Madhua or broadcast Thimate 10 per cent granules @ 10 Kg + 5 Kg Neem cake in 2-5 cm standing water in the field.

Stem borer

Stem borer 

Symptoms of damage:

1. 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.

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

3. 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.

4. During panicle exertion, severing of growing part from the base results in the drying out of panicles. Panicles may not emerge out at all and those that have already emerged do not produce grain.

5. The empty panicles are very conspicuous in field as they remain straight and whitish.

Control measures:

1. To control the insects like leaf roller, Case worm, Army insects etc. spray Chlorpyriphos 1 lit. or Endosulfan or Quinolphos 1.5 lit./ha and add Tipol 5 ml/10 lit.of water during at the time of spray.

2. To control Babhani insects spray Phosphymidon @4-5 ml/10 lit.of water or Monocrotophos @ 1 ml/lit. of water.

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
