• To control blast disease, retain water in the soil and apply a balanced dose of fertilizer.
• For control of blast disease, application of urea fertilizer in the affected land should be stopped and 8 gm of Trooper or 6 gm of Nativo or Tricyclazol / Strobin group fungicide should be mixed in 10 liters of water and applied twice in 5-7 days interval in every 5% of the land.
• In case of infestation of stem borer insects, collect and destroy the pile of eggs, use light traps, if the infestation is high, use approved pesticides.
• Use light traps to control leaf-rolling insects and perch on the ground. Avoid excessive use of urea fertilizer. If 25% of the leaves are damaged, apply one of the approved pesticides of Sevin 85 SP, Darsban 20 EC or Mipsin 75 WP in the correct dosage.
• 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.
• Rice bug infestation may occur during grain formation stage. Apply Carbaryl or Isoprocarb / MIPC group pesticides in approved doses if one Gandhi insect is found in 2-3 bunches on average.
• Drain out water from the land 15 days before harvest.

Only use moderate amounts of specific potent chemical pesticides or locally recommended organic pesticides if absolutely necessary.
• Apply pesticide after rain.

Horticultural crops

• Fruit orchards need to be intercultural operation.
• In case of infestation of weevil and fruit borer insects in the marble stage of mango trees, spray Cypermethrin group Ripcord / Basathrin 10 EC 1 ml or Fenitrathion group Sumithion 50 EC 1.12 ml per liter of water 2/3 times every 10-15 days interval for control.
• To control flies during mango maturation, Sumithion 50 EC of Phenitrothion group should be mixed with 1.12 ml per liter of water and sprayed in the late afternoon.
• In order to control coconut spiders, sprouts should be applied to the affected trees by cutting and burning the young coconut. In addition, spider mites should be applied on the young leaves of nearby trees.
