Abstract

Abstract

Cercospora arachidicola and Cercosporidium personatum sporulated abundantly on certain culture media, while on others they produced none to few conidia. On some media which failed to support sporulation, the addition of an aqueous extract of peanut leaves markedly increased sporulation.

Light was not required for sporulation by C. arachidicola but was essential for sporulation by C. personatum. No conidia were produced by C. personatum in suitable media in continuous darkness or orange light, while greatly reduced sporulation occurred in yellow, blue, green, or red light. The pathogenicity of C. personatum grown under various wavelengths of light was unaffected.
