Effect of different temperature, pH levels, and light intensity were tested against the growth of Alternaria solani under in vitro conditions. Mycelium growth and sporulation of Alternaria solani was significantly influenced with temperature. Maximum colony growth was recorded at 25oC followed by 30oC and minimum colony growth was recorded at 40oC. Excellent sporulation was noticed at 20oC and 25oC temperature. However, no sporulation was found at 40oC temperature. Effect of different pH level on colony diameter, sporulation and mycelium dry weight of Alternaria solani on PDA medium reveal that, the maximum colony diameter, dry weight were observed at 6.5 pH level followed by 6.0 pH level, while minimum colony diameter and dry weight were observed at 8.5 pH. Excellent sporulation was observed at pH level of 6.0 to 7.0, while poor sporulation was recorded at 4.0, 8.0 and 8.5 pH level. Light also influenced the colony growth and sporulation of Alternaria solani on PDA medium. Maximum colony growth and excellent sporulation was noticed at 12 hrs dark and 12 hrs light, minimum colony growth was observed at 8 hrs dark and 16 hrs light, good sporulation at 24 hrs light and 24 hrs dark and poor sporulation was observed at 8 hrs dark and16 hrs light and 8 hrs light and 16 hrs dark.
