Definition of lethal yellowing

A fatal disease of coconut and other palms. It
has swept through the coconut-growing regions of
Jamaica, Cuba, the Cayman Islands, and Florida,
and is presently destroying palms in the Yucatan.
The disease is caused by phytoplasmas and is
spread by plant-sucking insects called
plant-hoppers. The first visible sign is the
dropping of all fruit; this is followed by the
withering of new flowers, and yellowing leaves.
There is no effective cure; trees die within 3-6
months after appearance of the first symptoms.
