In this study, seven categories of pH as 3.5, 4.5, 5.5, 6.5, 7.5, 8.5, and 9.0 was taking under consideration and observations were recorded for each category of pH respectively, on growth and sporulation of Alternaria Lini in the crop linseed, Bundelkhand Region, India. The most favorable condition of pH for the radial growth and sporulation of the Alternaria lini on PDA were found 6.5 out of seven categories of pH. Highest mycelial radial growth was obtained 35 mm with pH 6.5 followed by 31.5 mm with pH 7.5, which is statistical significant (CD=4.67)at 5% level of significance. Whereas, lowest mycelial growth was found 8 mm with pH 3.5 followed by 8.5 mm with pH 9.0 Which is found at par at 5% level of significance. The results revealed that the mycelial radial growth and sporulation of Alternaria lini is increased from 8 to 35 mm with respect to increase of pH from 3.5 to 6.5. Further, the mycelial radial growth and sporulation of Alternaria lini was decreased from 31.5 mm to 8.5 with pH 7.5 to 9.0, respectively.
