Once the damage is identified based on symptoms, it is important to take up plant protection measures at the earliest. Usually the damaged tissue is removed and a suitable pesticide is applied to the damaged part. The part of damaged stem is drilled with a few holes and an effective chemical in appropriate dose is poured into the holes and sealed. The systemic pesticide will penetrate the stem tissues and kills the pest stages present. Even fumigation is resorted in some cases depending on the type of damage.
If any palm is killed, it is better to cut it into pieces, apply pesticide and finally burn. The material should be properly burnt to prevent escapes. Until the dead palm is disposed of, the adult weevils continue to emerge from inside and spread in the entire garden and cause great damage.
