The above said six plant extracts from Zimmu, Z. scabra, E. littorale, P. zeylanica, C. phlomoides and T. asiatica were also tested for their ability to inhibit spore germination of C. musae. The results indicated that the leaf extract of Zimmu and tuber extract of Z. scabra at 25% concentration were found to completely inhibit spore germination of C. musae, while none of the other plant extracts were found to have any inhibitory affect at this concentraion (Fig 2B). However, the leaf extract of P. zeylanica exhibited complete inhibition of spore germination only at its 50% conc. compared to other plant extracts.
