The earlier symptoms of the disease were observed in early rainy season. Disease started on young leaves as small necrotic lesions which later developed in to circular light to dark grey spots. These lesions gradually enlarged and turned brown or dark grey, resulting in early leaf senescence. In the advance stage of infection the inner necrotic spots looses brown or grey coloration and new dark grey spots encircled the older one by giving concentric ring appearance. The shrinkage around the necrotic spots in infected leaves was also observed which ultimately leading to leaf drying. Interestingly the disease infection was not observed systematic; but it was found localised to various regions. The infection spreads severely as the rainy season progressed when temperatures ranged from 25 to 30°C and lasts up to winter season. The progressive stages of leaf spot infection are depicted in Figure 1(c) whereas, severe infection in natural field conditions and on collected leaves is showed in Figure 1 (a & b).
