Abstract
Fifteen samples of rhizospheric soil of Eucalyptus sp. were collected from various localities of Karachi. By using serial
dilution method, six fungal species (Aspergillus flavus, A. niger, A. parasiticus, A. restritus, A. terreus, and Rhizopus
sp.) were isolated, out of which A. niger found highest and dominant fungus isolated from the tested samples as
compared to other fungi. Root plating of Eucalyptus sp. found best method for isolation of infectious fungi.
Colonization of M. phaseolina were recorded as the most abundant in three samples; zoology department, maskun gate
and M.A Jinnah road. R. solani found to be the most predominant fungus in two samples; botanic garden and NIPA. F.
solani and F. oxysporum were observed relatively less as compared M. phaseolina and R. solani where its highest
percentage found only in zoology department sample. Furthermore, thirteen homeopathic medicines (Q) were used to
find out the best antifungal drugs (using paper disc and well methods) against soil borne fungal species isolated from
the rhizosphere and rhizoplane soil of Eucalyptus sp. Out of thirteen, only two drugs Rosmarinus officinalis and
Arsenic album showed significant (p<0.05) growth inhibition of F. oxysporum. Well method was found to be better in
comparison of paper disc method, while other homeopathic drugs were unable to produce any inhibition in growth of
pathogenic fungi.
