Main Crops Stage Pest & Diseases Advisory

Please keep clean the pond & apply lime as per recommendation (Water & soil

testing) Indian major carp & Foreign carp can be released in pond @

2000 pieces fingerling. Please maintain the recommended ratio.

Complementary feed must be given regularly. Don’t use excess feed to

avoid water pollution.

For Aphid, hoppers, white fly apply Imidachloropid @1ml/5lit. of water or thiomethoxam @1g/3lit of water. For yellow mite apply propergite 2.5 ml/lt. of water.to control

sucking pest of chilli apply Flubenamide 39.35% SC @ 4 ml/tank. Bacterial wilt control measure same as Brinjal, In case of blight of twigs from the top of the plant need to be sprayed with Difenoconazole 25 EC @ 1ml/lit of water.

Name of

Animal

Disease

Cattle and

Buffalo

Lumpy skin disease Lumpy skin disease- is an infectious disease in cattle caused

by a virus, also known as Neethling virus. Symptom- by fever, enlarged superficial lymph nodes and multiple nodules

on the skin and mucous membranes. Infected cattle also may

develop edematous swelling in their limbs and exhibit lameness. Additionally, the disease often results in chronic

debility, reduced milk production, poor growth, infertility,

abortion, and sometimes death. Control: This disease is new in our country and still doesn’t have any vaccine. Isolate

infected cattle firstly, keep clean the cattle house. Treatments

will be according to symptom. For fever use Paracetamol or

Meloxicam. The lumps and nodules can be cleaned with Potassium permanganate mixed water. In need you can use

Antiseptic lotion. Consult with nearest veterinary in

emergency.

Poultry

Round worm and Tape worm

Never allow chickens or ducks to eat wet or damp feed during

this rainy season.

It is very important to provide particular amount of dewormers

for both round worm and tape worm to any cattle, goats or

poultry at this time.

Crop Stage Variety Advisory

RICE

Sheath blight Due to stagnation of water in the field and high

relative humidity Sheath

blight Fungal disease is common. Excess Nitrogen fertilizer

application can accelerate

this disease. August to October is the high time for this disease

attack. Control: 1)

Drain out excess water from infected field. 2) Reduce the dose

of Nitrogen fertilizer. 3)

Bio fungicide like Trichoderma, Pseudomonas Fluorescens is

also good. 4) Spray

Propiconazol+ Difenoconazole 1ml/liter of water or

Carbendazim + Flusilazole 1.5

ml/lit or Carbendazim (Bavistin) 1 gram/liter of water. Yellow

Stem Borer- The larva

of borer makes hole in the stem 2-4 inch above the water

level. Affected plants show

‘Dead heart’ symptom. In the reproductive stage it shows

‘White ear head’. In 110

days, variety pesticide is not required within 30 days after

transplanting. Pesticide

needed if there is 5% dead tiller or 1% dead inflorescence.

Control: i) Apply granular

insecticide 8 to 10 days prior the transplanting and retain

water in nursery field. ii)

Spray 2 ml Fipronil or 2.5 ml Acetamiprid + Chlorpyriphos

par liter of water. iii) cut

off the tip of the seedlings before transplanting to eradicate the

eggs of stem borer. iv)

Light trap or hand net can be used. Do not use Imidacloprid or

Thiamethoxem as

precaution.

TOMATO --

Leaf Curl: 1. Spray 12.5 g of Diafenthuron and 25 ml of

Eoxystrobin + Tebuconazole

per tank of water. 2. On the second day, spray 15 g of Zinc

EDTA and 30 g of Boron

30 g as each tank. 3. After seven days, play Diafenthuron 12.5

mailto:[email protected]/liter

gm per tank. 4. After 7

days, spray aloe vera with 12.5 g of diafenthuron + 25 ml of

tebuconazole per tank..

BRINJAL

Yellowing of leaf and Fruit drop: Such problems are due to

lack of zinc

nutrients in the soil and whitefly infestation. 1. As the first

spray, spray zinc

EDTA in 1 gram per liter of water. 2. On the second day,

spray 12.5 g of

diafenthuron and 25 ml of eoxystrobin + teboconazole per 15

liters of water. 3.

After seven days, spray Diafenthuron 12 gm in 15 liters of

water. 4. After

seven days, spray zinc EDTA in 1 gm per liter of water. 5. Cut

the lower leaves

of the tree, lighten the tree. Let the wind blow.

CAULIFLOWE

R

This is the time when those who have planted cauliflower

early may have

problems-1. leaf may turn yellow. 2. The roots of the tree may

rot 3. The roots

may be damaged etc. To control these: 1. The soil should be

sprayed with 40 g

of copper oxychloride and 1 g of streotocyclin per 10 liters of

water. 2. After

seven days, the mixture of azoxystrobin + tebuconazole

should be sprayed in 1

ml per liter of water. 3. After seven days, four grams of copper

oxychloride

and 2 ml of validamycin per liter of water should be sprayed

well.

COW

Bovine Ephimeral Fever caused by a virus are carried by mosquitoes. Symptoms of severely infected animals are the main treatment. The cowshed should be clean and mosquitoes, flies should be controlled to prevent disease transmission.

Pond preparation

Undulating Red and Laterite Zone Crop Stage Problem Advisory

RICE Prevailing weather is favorable for an attack of Brown Plant Hopper (BPH) and white

Backed Plant Hopper (WBPH). To manage farmers are directed to follow a spray

schedule with Buprofezin 25% SC@ 0.5 ml/l or Thiamethoxam 25% [email protected] gm/l or

Imidacloprid 17.8%SL@ 0.3 ml/l or neem oil @ 2 ml/l of water 2-3 times at an

interval of 7-10 days in the early morning or evening hours of any bright sunny day.

Forecasted weather is favorable for Blast, sheath blight, brown spot disease attack in

rice. To manage the disease spray Propiconazole or Hexaconazole @ 1 gm/L of water

after the cessation of rain. There may be an attack of yellow stem borer, Case worm,

leaf folder at this stage of kharif rice. Keep vigilance. If severe infestation is observed,

application of Cartap hydrochloride 4G @3.5kg/bigha or Chlorantraniliprole 0.4 GR

@ 1.3 kg/bigha or fipronil 0.3% GR @ 0.7-1 kg/bigha are advised to protect the crop

from these pests.

CHILLI Prevailing weather is favorable for Anthracnose in Chilli. To manage farmers

are advised to use Difeconazole 25 % EC or Hexaconazole 5% SC @ 1ml/ l +

Captafol/ Chlorothalonil/ Mancozeb 1-1.5 gm/l of water twice at 7-10 days

interval. In current weather situation thrips mite and whitefly attack may be

increased in chilli which may cause turning of leaves and stunted growth of the

plant. To control the pest attack spray spiromesifen 22.9 % SC 0.5 ml/ lit of

water. Rogue out the affected plant from the field immediately to prevent the

further spreading of the diseases.

PUMPKIN Prevailing weather is congenial for mosaic disease in cucurbitaceous

vegetable. Rogue out the affected plant from the field immediately to prevent

the further spreading of the diseases. Farmers are advised to spray Flonicamid

50% WG @ 0.3 gm/l with sticker on a clear sunny day to prevent the disease.

COW Lumpy skin disease may be seen in cattle during the prevalent weather. Infected cattle

may develop edematous swelling in their limbs, multiple nodules on their skin and

mucous membranes fever etc. For control spreading of the disease isolate the infected

cattle firstly, clean the cattle shed with lime and bleaching powder and wash the lumps

and nodules of the infected cattle with 5% Potassium Permanganate solution mixed

with water.
