Pest and Disease
Spike disease is one of the important diseases of sandal. This disease is caused by mycoplasma-like organisms (MLO). It can occur at any stage of development of the tree. As the disease progresses, the new leaves become smaller, narrower or more pointed and fewer in number with each successive year until the new shoots give an appearance of fine spike. At the advance stage of disease the inter nodal distance on twigs becomes small, haustorial connection between the host and sandal breaks and the plant dies in about 2 to 3 years.
Spread of disease is sporadic and the disease is transmitted in nature by insect vectors. It has been found that other insect vectors in addition to Nephotettix virescens may also be responsible for transmission of disease. So far no permanent remedial measures have been prescribed for control of spike disease.
Stem borers Zeuzera coffease Nietn (red borer) Indarbela quardinotata Walker (bark-feeding caterpillar) and Aristobia octofasiculata Aurivillius (heartwood borer) are some of the pests causing considerable damage to living trees.
