About Sandalwood Spike Disease (SSD):
- It is caused by phytoplasma — bacterial parasites of plant tissues — which are transmitted by insect vectors.
- The disease was first reported in Kodagu in 1899.
- It is being classified as “vulnerable” by the International Union for Conservation of Nature in 1998.
- Presently, there is no option but to cut down and remove the infected tree to prevent the spread of the disease.
- Between 1 and 5% of sandalwood trees lost every year due to the disease.
- SSD has been one of the major causes for the decline in sandalwood production in the country for over a century.
