The disease turns the leaves yellow and causes most of the fruits to drop prematurely. The whole crown of the palm also falls, leaving a bare trunk, experts from the coconut research institute said.
As a preventive measure, the institute has declared a three kilometer wide buffer zone along the coastal line in the south, ranging from Weligama, 140 kilometers south of Colombo, to Matara which is situated a further 20 kilometers away.

The coconut trees that were infected within the buffer zone had been burnt to prevent the spreading of the bacteria.
The research institute has started conducting experiments to find a solution a
