Abstract
Tospoviruses are enveloped isometric RNA viruses with a tripartite genome
containing small, medium, and large segments of ssRNA. They are transmitted by
thrips in a propagative manner and are one of the most important plant virus
groups infecting a wide range of economically important crop plants all over the
world. Tospoviruses have emerged as serious viral pathogens affecting the
cultivation of several field and horticultural crops. In the Indian
subcontinent, due to their economic impact on a wide range of important crops,
most of the research was carried out only in India, although tospoviral diseases
cause significant problems in several other countries in the subcontinent
including Bangladesh, Nepal, Pakistan, and Sri Lanka. This review aims to
highlight emerging disease problems, virus characteristics, vectors, diagnosis,
epidemiology, and management of tospoviruses in the Indian subcontinent.
