Nature of damage:
------------------

• Damage is due to mining into leaves and petiole by larvae.
• The photosynthetic ability of the plants is often greatly reduced as the chlorophyll containing cells are destroyed.
• Severely infected leaves dry up and fall.

Management :
-------------

• Collect and destroy mined leaves.
• Avoidance of hybrids and judicious application of nitrogen fertilizers in pest endemic area.
• Removal and destruction of infested leaves followed by an application of NSKE 4 % with a sticker (0.5 ml/lit of water).
• Spraying with imidacloprid 17.8 Sl @ 0.3 ml/lit of water during early stages of crop growth before flowering.
• Application of dichlorvos @ 0.03% in severe infestation during reproductive phase of the crop.
