Pulse beetle management in gram

  • The population of Pulse beetle has been observed rapidly after 60 days of stored granular storage period.
  • Due to the initial loss due to transplantation of beetle in gram, 87.23% seed damage and 37.15% weight loss were observed within 120 days of storage.
  • In various oils and plant products tested, Neem and castor oil @ 6 ml/kg seed proved effective for four months of storage.
  • Coat the seed with small quantities of vegetable oil or mix neem leaves in the stored grain.
  • Dip jute bag in 10% Malathion solution.
  • use airtight storage structure.
  • Fumigation with aluminum phosphide protects the seed without affecting the viability.

Control of Root Aphid in Wheat

  • This insect is active from November to February.
  • Damage is more in rainfed and late sown crop.
  • Yellowing of young plants is observed due to root aphids. In this case minute yellowish brown aphids may be present near the base or on the roots of the plant.
  • Aphids also vector a viral disease named barley yellow dwarf virus (BYD). Yield of infected wheat plants can be reduced by 50%.

Control-

  • Avoid late sowing.
  • Avoid use excess nitrogen fertilizers.
  • If the infestation in standing crop, Spray imidacloprid 17.8% SL @ 60-70 ml/acre.
  • Or apply thiamethoxam 25% WG @ 100 gm/acre in soil with fertilizer/Sand/soil before irrigation.

How to control Armyworm/ Cutworm in Wheat

    • The primary symptom is defoliation of the plant.
    • Larvae feed on the leaves, chewing from the edges to the midrib, or on the head of cereal plants.
    • Heavy infestations can be very destructive; larvae may climb the plant. Some species may be found feeding at the soil surface, others, underground feeding on roots, and then there are some who feed inside the stem.
    • The armyworm feeds during dawn and dusk period as it is actually shy of sunlight.


    Management –

    • Look for larvae and signs of damage beginning in early spring. Caterpillars will often be found feeding on the undersides of leaves and on fresh growth. Handpick the worms you discover and don’t be tempted to crush them between your thumbs. Instead, drop them in a bucket of soapy water. 
    • Use 4-5 bird perches to attract birds.
    • Spray Emamectin Benzoate 5% SG @ 100 Gm per acre.
    • Spray fipronil 5% SC @ 400 ml per acre.

Management of Yellow Mosaic Disease in Okra/Bhindi

Yellow Mosaic Disease in Okra/Bhindi:-

  • This is the most important and destructive viral disease in bhindi.
  • The disease infects at all the stages of crop growth and severely reduces growth and yield.
  • The disease is transmitted by whitefly.
  • The characteristic symptoms of the disease are a homogenous interwoven network of yellow veins enclosing islands of green tissues.
  • Initially, infected leaves exhibit only yellow coloured veins but in the later stages, the entire leaf turns completely yellow.
  • The fruits of the infected plants exhibit pale yellow colour, deformed, small and tough in texture.

Control-

  • Remove and destroy disease-affected leaves/plants from crop fields to avoid secondary spread.
  • Parbhani Kranti, Janardhan, Haritha, Arka Anamika and Arka Abhay can tolerate yellow vein mosaic.
  • Do not use high fertilizer during plant growth.
  • Do not roted okra with other hosts of virus.
  • If possible, choose early planting to the controlling of yellow mosaic virus disease.
  • Keep sanitation while using any tools that are using in crop.
  • Use 4-5 sticky trap/acre to the controlling of whitefly infestation.
  • Spray imidacloprid 17.8% SL 80 ml/acre for the controlling of whitefly.
  • Spray dimethoate 30% EC 250 ml/acre of water.

Management of Termites in Wheat

Management of Termites in Wheat:-

  • Termites damage the crop soon after sowing and sometimes near maturity.
  • They feed on roots, stems of growing plants, even dead tissues of plant feeding on cellulose.
  • The damaged plants dry up completely and are easily pulled out.
  • The plants damaged at later stages give rise to white ears.
  • Infestation is heavy under unirrigated conditions and in the fields where un-decomposed farmyard manure is applied before sowing.

Management –

  • Apply deep ploughing before sowing.
  • Use well rotten FYM in field.
  • Fill kerosine in mound of termite.
  • The seed should be treated with Chlorpyriphos (20% EC) @ 5 ml/kg of seed before sowing.
  • Broadcast Chlorpyriphos (20% EC)@ 1 litre/Acre with any fertilizer.

Aphids Attack in Chilli Crop:-

  • Nymphs and adults are both soft bodied pear shaped, blackish in colour.
  • Appear on the tender shoots, leaves and on the lower surface of the leaves.
  • Suck the sap and reduce the vigor of the plant.
  • Secrete sweet substances which attract ants and develop sooty mold.

Control:-Spray the crop with Following insecticides at 15-20 days interval till the end of aphid population checked.

  1. Profenofos 50% EC @ 50 ml/ Pump.
  2. Acetamiprid 20 SP @ 10 gm/Pump.

Management of Thrips in Cotton

Management of Thrips in Cotton:-

Nature of Damage of Thrips:-

  • Nymphs and adults lacerate the tissue and suck the sap from the upper and lower surfaces of leaves.They inject saliva and suck the lysed contents of plant cells resulting in silvery or brown necrotic spots.
  • Seedlings infested with thrips grow slow and the leaves become wrinkled curl upwards and distorted with white shiny patches.
  • Rusty appearances in patches develop on under surface of leaves.
  • Higher infestation during vegetative crop growth results in late bud formation.
  • During the fruiting phase there is premature dropping of squares and the crop maturity is delayed combined with yield reduction.
  • The feeding by thrips on the developing bolls late in the season cause spots or wounds on the ripening of the ball or the quality of the seed.

Management:-

  • Seed treatment – Imidacloprid 60 FS @ 10 ml/kg or thiamethoxam 70 WS @ 5 g/kg seeds applied as seed treatment are efficient in suppressing the population of other sucking pest on cotton seedling.
  • Maintaining weed free conditions in cotton field from the spread of development of thrips.
  • Insecticidal options should be made when thrips infection results in high grade injury during clear sky period with no anticipated rains.
  • Spray of NSKE prepared on farm or crude neem oil spray @ 75 ml per pump suppress thrips population during pre squaring crop stage in both cases detergent / soap powder @ 1 gm / litre of spray fluid is to be added for getting uniform spray suspension.
  • Chemical Spray:- Spray any one Following insecticide.
  1. Profenofos 50% EC @ 50 ml/ Pump.
  2. Acetamiprid 20 SP @ 15 gm/Pump.
  3. Imidacloprid 17.8% SL @ 7 ml/pump.
  4. Thiamethoxam 25% WG @ 5 gm/pump.
