Abstract

The fungus Alternaria macrospora Zimm. grow well in host leaf dextrose extract and Czapek's solution. The fungus attained maximum growth after 14 days of incubation. Sucrose was found to be the best carbon source while sodium nitrate and urea supported good growth of the fungus among various inorganic and organic nitrogen sources. A pH range of 5 to 7 and a temperature of 27° C were found to be optimum for the growth of the fungus.
