The Department of Agriculture, South Andaman, has reported an infestation of Rugose Spiraling Whitefly (RSW), primarily affecting coconut palms. The pest has also been observed in Arecanut, banana, guava, and solanaceous vegetables. Additionally, traces of mealy bug infestation have been detected in papaya and ornamental crops.
The Rugose Spiraling Whitefly feeds on the underside of leaves, leaving behind excessive honeydew on the upper surface. This sticky residue encourages the growth of sooty mould, which can weaken plants. Experts warn that a prolonged dry spell and decreasing relative humidity could further accelerate the spread of the pest.
A recent survey by the Department’s extension functionaries indicates that the infestation remains below the Economic Threshold Level (ETL) in most areas. However, some patches show slightly higher levels of infestation, prompting urgent intervention to prevent wider spread.
To tackle the issue, the Department has formulated a comprehensive pest control strategy, which includes:
- Formation of a Pest Control Task Force comprising Agricultural Extension Officers.
– Active participation of Panchayati Raj Institutions (PRIs) in survey, execution, and feedback.
– Field monitoring by Extension staff and PRI members, with immediate reporting of pest severity.
– Spraying of Azadirachtin 0.3% EC in affected fields, starting from Chouldari Village on March 7, 2025.
The spraying campaign will be carried out on a priority basis in severely affected areas.
The Agriculture Department has urged farmers across all zones to promptly report any pest activity to their nearest Sub Depot, Extension Functionaries, PRIs, or the Kisan Call Centre at 03192-243434 or 1800-345-1145 (available on all working days).
Additionally, awareness and training programs will continue to educate farmers on effective pest management techniques.
With the changing weather conditions posing a risk of wider infestation, authorities are calling for immediate cooperation from farmers and local governing bodies to ensure a swift and effective response.
