Abstract: Use of aqueous extract of leaves, stem, bark and fruit Eucalyptus sp., in the control of root rot fungi viz., Fusarium sp., Rhizoctonia solani and Macrophomina phaseolina by paper disc and well methods were examined. R. solani was less susceptible than Fusarium sp., and M. phaseolina. Aqueous extract of leaves, stem, bark and fruit of Eucalyptus sp., was more effective @ 5% w/v against M. phaseolina, R. solani and Fusarium sp. Soil amendment with leaves, stem, bark and fruit of Eucalyptus sp., @ 5% w/w showed significant increase in germination, shoot length, shoot weight, root length and root weight of chick-pea and mung bean plants. Besides this, the infection by Fusarium sp., M. phaseolina, R. solani was also reduced. All parts of Eucalyptus sp., were equally effective in the control of root infecting fungi.
