In our country, tomato (Lycopersicon esculentum Mill.) is cultivated throughout the year because of the favourable agroclimatic conditions in our part or another. They also prefer warm growing season. High humidity and high temperature makes the tomato plants susceptible towards foliage disease. Root elongation and root initiation were reduced due to the infection of virus. At the time of germination there was not so much difference between the root initiation of healthy and infected tomato plant, but as the intensity of disease was increased the root initiation was decreased and thus inhibiting the mergence of new root initials.
