Abstract : A study of total sugars (T.S), reducing sugars (RS) and non-reducing sugars (NRS) of the infected tissues of tomato cultivars Pusa Ruby and S-22 was carried out during 2nd day to 14th days pathogenesis by Alternaria solani. In this research it is investigated by taking the fruit extract of fixed volume of tomato pulp of two cultivars at definite intervals, till 14 days pathogenesis. Reducing and non-reducing sugars were estimated by colorimetric method and rate of decrease in sugar contents after infection of Alternaria solani was found out .
