Introduction

Sugarcane mosaic virus (SCMV) is a potyvirus infecting sugarcane and other members of Graminae. Several isolates of SCMV naturally infecting sugarcane, maize, sorgum, pearl millet, finger millet in different parts of the country.it is also known to occur as mixed infection with Sugarcane streak mosaic virus.
