After my post graduation and Ph.D. in botany with plant virology specialization, I have carried out research as scientist in Indian Council of Agricultural Research for a period of 28 years on plant virus and virus-like diseases of horticultural and oil seed crops and published 80 research articles. During 2010 to 2014 I have published 4 reference books from Springer publishers. Presently I am finalizing "Encyclopaedia of plant virus and viroid diseases" along with other 3 internationally known virologists.
Dr. K Subramanya Sastry has joined in ICAR at Indian Institute of Horticultural Research, Bangalore in 1971 as scientist and subsequently he has worked at Directorate of oil-seeds research and also at Directorate of Sorghum Research, Hyderabad and retired as Principal Scientist.

It is well established that the virus and viroid diseases in different crops cause enormous losses in terms of quantity and quality of products (see Chapter-3 of Volume-I) (Sastry 2013b). Because of the serious losses they cause to agriculture and horticulture, virus/viroid diseases have acquired great importance in the realm of plant pathology and call for effective management measures against them. These diseases are not amenable to control by direct methods. Unlike fungicides and bactericides, no commercial viricides have yet been developed. However a number of indirect control measures for different crop plant-virus/viroid pathosystems suitable to varied agro ecosystems have been developed with an aim to avoid the pathogen or to minimize their impact on crop yields (Thresh 2003, 2006). As these diseases routinely cause systemic infections and have very effective methods of transmission, preventing their spread has become a complicated problem. Some diseases like Tobacco mosaic virus (TMV), Potato virus X (PVX), Cucumber green mottle virus (CGMMV), Citrus exocortis viroid (CEVd) and Potato spindle tuber viroid (PSTVd) are highly contagious and affect large number of hosts belonging to several families.

Virus and viroid diseases are economically important because of the losses they cause in productivity and quality of the plant products. The profitable crop production depends on the appropriate diagnosis of the etiological agents and application of management measures.
