Cladosporium herbarum for the solid and broth media both. Aegle marmelos extract was found most effective in inhibiting the mycelia growth of Cladosporium herbarum where as Cassia fistula extract was least effective. The presence of antifungal compounds, in higher plants, has long been recognized as an important factor in disease resistance Mahadevan, (1982).
