Symptoms:

The leaf mining weevil was considered as a minor pest, but in recent past this pest is attaining serious proportion during rainy season on new emerging leaves causing complete leaf damage. These minute weevils also bite and deposit eggs on tender leaves.  On hatching, the grubs mine the leaves and feed within. Affected leaves turn reddish-brown, crumple, dry and fall off.  Occasionally it attacks inflorescence also.

Control

·         Spray quinolphos @ 2.5 mL/L at new flush emergence.
