Ceratocystis fimbriata causing wilt of pomegranate, grew well in all most all hydrogen ion (pH) concentration from 2.0 to 11.0. It indicates fungus present in all soil types and locations. Maximum growth was recorded at a of pH 7.5 (9.69 g), which was on par with pH 7.0 (8.92 g) and pH 8.00 (8.28 g). The growth of the fungus decreased below from pH 5.5 onwards and above pH 9.0. Lowest growth was observed at pH 2.0 (0.04 g). Followed by pH 2.5 (0.08 g). The fungus grew well in lower temperature to highest. It shows fungus present more in dry area and cause severe disease than cool area. The maximum growth of the fungus (7.76 g) was observed at a temperature of 30˚C. Growth at 25˚C (7.47g) were found to be on par temperature at 20˚C (5.97g) and at 35˚C (5.46g). The fungus grew very little at 10˚C (1.39g), 15˚C (2.46g) and 40˚C (1.36g) and failed to grow at 45˚C (0.66 g).
