• If the seedbed becomes yellow, apply urea at the rate of 283 gm urea per decimal. If the seedlings are not green even after application of urea, gypsum fertilizer should be applied at the rate of 400 gm per decimal of land.

• Use light traps to protect the seedbed from the attack of brown plan hoppers. Catch the insects with the hand net and kill them. If the attack is high 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 liters of malathion or 1.6 kg carbaryl or 1.12 kg isoprocarb / MIPC per hectare

Wheat

• Provide first irrigation during three leaves of seedlings (17-21 days after sowing), second irrigation during heading (50-55 days after sowing) and third irrigation during grain formation (75-80 days after sowing).
• Wheat heading are wet for 12-24 hours and the temperature is 16 degrees Celsius or more than that can lead to blast infection. Once during heading out as a preventive measure to control the disease, it is necessary to spray Nativo 75 WG or Navita 75 WG at the rate of 6 gm in 10 liters of water once and after 12-15 days.

• Care should be taken to ensure that no water accumulates in the soil during flowering and grain formation of maize.

Mustard

• Aphid can attack the mustard plant during flowering and fruiting. Only 50 gms of neem seeds should be broken, soaked in 1 liter of water for 12 hours, mixed with 2-3 gms of powdered soap and sprayed twice every 7 days. 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.
• In cold and humid weather, mustard stem rot can be attacked. As soon as the disease appears, apply Rovral 2.0 g / liter in water 3 times (growth stage, flower and grain formation stage).

• Mustard leaves should be sprayed 3-4 times in 10-12 days at the rate of Rover-50WP 0.2% (2 g per liter of water) mixed with water to control disease and as soon as the disease appears.

• Provide irrigation as required.

• In case of infestation of eggplant tip and fruit borer insects, cut and destroy the affected tip along with the insects. Insect reproduction is likely to be greatly reduced by using pheromone traps. Use spray of approval dose of insecticides, if necessary or recommended local organic insecticides may be used.
• In case of infestation of fruit borers in bean, control the insects by using IPM method.
• In case of fly infestation in pumpkin vegetables, use pheromone and poison traps together. Pesticides of alpha ciphermethrin group can be used.
• In case of powdery mildew in pumpkin vegetables, apply hexaconazole or mencozeb.
• In case of Aphid attack in vegetables, use the approved dose of Malathion group pesticide.
• In case of mite infestation in chilli, 1 kg half-broken neem seeds in 20 liters of water for 24 hours and spray the water (after chopping) on ​​the underside of the leaves.
