Aman

• In case of infestation of stem borer insects, apply 180-190 gm of Cartap group or 10 gm of Thiamethoxam + Chlorantraniliprol group of pesticides per bigha for control.
• Dew or drizzle rain is conducive to blast disease. In this type of weather, once in a while and 5-7 days after the emergence of heading, apply 54 gm of Trooper 75 WP / Difa 75 WP / Jill 75 WP or 33 gm of Nativo 75 WG or Tricyclazol / Strabin only per bigha of land. Mix well in 67 liter of water and spray in the last afternoon.
• Use light traps to control insects.
• Drain out water from the paddy field 15 days before harvesting
• If the crop is 80% mature, collect it in a sunny day.

Boro Paddy:

Seedbed-

• Use light traps to protect the seedbed from the attack of brown tree hoppers. Catch the insects with the net and kill them. In case of infestation, apply 125 ml imidacloprid per hectare.
• In case of thrips infestation, apply nitrogen fertilizer on the affected land. In case of high infestation apply 1.12 liter malathion or 1.7 kg carbaryl or 1.12 kg isoprocarb / MIPC per hectare.

Wheat:

• Apply first irrigation during three leaf cycle (17-21 days after sowing), second irrigation at heading stage (50-55 days after sowing) and third irrigation at grain formation (75-80 days after sowing).
• In case of rust disease of wheat leaves, Propiconazole should be mixed at the rate of 0.5 ml per liter of water or Tebuconazole at the rate of 1 ml per liter of water and sprayed 2-3 times after 10 days.
• In case of root rot disease in wheat field, Carbendazim or Carboxin + Thiram should be mixed at the rate of 2 gm per liter of water and sprayed in the soil at the base of the plant.

Potato:

• In case of infestation of cutworm, look for infected cut potato plant, turn the soil around it, find the worm, collect it and kill it. Insect infestation is high and pheromone traps and insecticides can be used to control insects. In addition, Chlorpyrifos 20 EC at the rate of 5 ml per liter of water should be mixed and sprayed on the roots and soil of the plant.
• Late blight is more likely to occur in the current weather. In this condition, after 7 days, the approved fungicide of Mancozeb group should be sprayed at the rate of 2 gm per liter of water and the plant should be well soaked. In case of disease, irrigation should be stopped in the affected land till the disease is controlled. As soon as the disease appears in one's own field or in the adjoining field, the plants should be well watered by spraying the approved fungicide.
• Apply irrigation, as per requirement.

Mustard:

• The first irrigation should be given within 20-25 days of sowing (before flowering) and the second irrigation should be given within 50-55 days (during fruiting).
• Aphid insects may attack during flowering and fruiting of mustard plants. Only 50 g of neem seeds should be broken and soaked in 1 liter of water for 12 hours. In case of severe infestation, Malathion 57 EC should be mixed in 2 ml per liter of water and sprayed twice in 10 days’ interval after 3 pm.

Maize:

• Continue sowing the seeds. Apply first irrigation within 15-20 days of sowing, second irrigation within 30-35 days, third irrigation within 60-70 days and fourth irrigation within 85-89 days.

Vegetables

• In case of infestation of eggplant tip and fruit borer insects, cut and destroy the affected tip along with the insects. Insect reproduction can be greatly reduced by using pheromone traps. Only use moderate amounts of specific potent chemical pesticides or locally recommended organic pesticides if absolutely necessary.
• In case of infestation of flies in pumpkin vegetables, use pheromone and bisotop traps together. Pesticides of alpha cypermethrin group can be used.
• In case of powdery mildew in Gourd vegetables, apply hexaconazole or mancozeb.
• In case of infestation of aphid insects in beans and cabbage, apply approved pesticides of Chlorpyrifos group.
• Thrips infestation can be controlled using adhesive white traps (40 per hectare). If the infestation is severe, fipronil or dimethoate can be sprayed at the rate of 10 ml in 10 liters of water.
• Apply light irrigation and pesticides, if necessary.

Horticultural crops

• Fruit orchards need to be intercultural operation.

• In case of symptoms of Sigatoka disease on banana leaves, 0.5 ml of Score or 2 g of Noin or Bavistin or 0.1 ml of Econazole / Folico should be mixed in every liter of water and sprayed 2-3 times at intervals of 15-20 days.

• Apply Isoprocarb (MIPC) group pesticide if banana beetle infestation occurs.
• If millibugs attack guava, use approved pesticides. This insect can also be controlled by spraying powdered soap at the rate of 5 grams per liter of water.
• Take necessary action in case of infestation of fruit flies in guava.
• Apply light irrigation and pesticides, if necessary.

Livestock:

• Vaccinate cattle regularly to prevent disease.

• Keep the cow house dry and clean.
• Black polythene or sacks can be used around the house to protect the floor from the cold and wind to prevent cold.

Poultry:

• Vaccinate poultry to prevent disease.

• If there are deciduous trees on the banks of the pond, clean the leaves regularly. 

• If the pH in the pond water is between 7-8, apply 1 kg of dolochun and 1 kg of salt per cent every 15 to 20 days or one-month interval at the beginning of winter. If the pH is low, the amount of lime should be increased.
• When the water level in the pond decreases in winter, supply water as required. Keep the concentration of fish normal or low.
• If the pond water is contaminated, change the water.
