Thielaviopsis paradoxa is an ascomyceteous fast growing fungus has broad host range under tropical condition. The growth dynamics and sporulation of this pathogen have been investigated in relation to various media, physical factors like temperature and pH with significant variation among the treatments. All 12 media supported growth although with a change in their dynamics. Maximum radial growth were recorded on PDA, PSA, MEA and OMA media and the optimum temperature for growth was 30oC although the cardinal temperatures were 10oC and 40oC. No growth was found on PDA at temperature 40oC and very scanty growth at 10oC, after 96hrs of incubation. Optimum pH for growth was 5.0 and 6.0. Least growth recorded both on CDA medium and at pH of 9.0. Highest sporulation recorded on OMA medium and temperature at 30oC and pH 6.0 on PDA whereas lowest sporulation found at pH 8.0 on PDA and on CDA medium.
