The lowest test concentration (50 μg/ml) of extracts of Cz bark prepared into acetone
and that of Cz leaf into petroleum ether and ethanol exhibited complete inhibition (100%) of spore
germination in both the moulds. At 100 μg/ml concentration all the extracts showed about 50 to
100% inhibition. However, the treatment of the spores of the two fungal species with highest
concentration (500 μg/ml) of bark and leaf extracts in all the solvents showed 100% fungicidal
activity as it completely arrestedthe germination of spores. Relatively lower activity of aqueous
extracts at 50 and 100 μg/ml concentrations suggests that the antifungal ingredients present in Cz
bark and leaf are more soluble in organic solvents than water.
