Abstract: | The in vitro fungitoxicity of the essential oil (EO), crude extracts, dried fractions and ursolic acid (UA) isolated from the abundantly available and underutilised leaves of Eucalyptus hybrid (Eucalyptus camaldulensis × Eucalyptus tereticornis) was assessed against three plant pathogenic fungi Aspergillus niger, Fusarium solani and Ganoderma lucidum causing pathogenesis in seeds, seedlings and trees, respectively, and Trametes versicolor and Pycnoporous sanguineus making wood to decay. The EO, methanol extract and UA demonstrated varied antifungal activity against all the fungi with minimum inhibitory concentrations ranging from 0.5 to 3.0%. The results of the study demonstrate a new chemical utilisation approach of the leaves of Eucalyptus hybrid towards the development of biofungicides in the management of above fungi of common occurrence in Indian forestry. |
