Abstract: Fruit rot of tomato caused by Alternaria solani is an important disease causing constraint and yield loss in tomato production in Manipur. Surveys on the incidence of fruit rot of tomato were conducted during November to April, 2015-2016 at different locations in the valley districts of Manipur where tomato are grown viz., Imphal East, Imphal West, Thoubal and Bishnupur. The disease incidence ranged from 44.5 to 76.67%. The district wise maximum intensity of disease was found in Imphal West district (60.78%) and minimum in Thoubal (55.60%). The effect of different cultural media on mycelial growth and sporulation of A. solani showed that maximum linear growth of the fungus was found in Oat meal agar (83.67mm) and least in Elliote’s agar (28.00mm) in solid media. In case of liquid media maximum growth was found in Potato dextrose broth (433.13 mg) and minimum in Host extract broth (13mg). However, the maximum sporulation was found in Potato dextrose agar (40X103spores/ml). This study will help to report the situation of fruit rot disease of tomato in Manipur and provide useful ideas for further investigations on the physiology and taxonomic study of the fungus.
