Antifungalactivity of cedrus deodara root oil against various fungal isolates

ABSTRACT

Antifungal activity of Cedrus deodara root oil against Aspergillus niger, Aspergillus flavus, Fusarium solani, Fusarium oxysporum, Rhizoctonia solani and Macrophomina phaseolina has been investigated using disc diffusion and well method. The maximum zone of inhibition of 6 mm was noted for Rhizoctonia solani for oil concentrations of 160 and 170 microg/disc while only 5 mm for 100, 120 and 140 microg/disc, respectively by disc diffusion method. No significant response has been observed against Fusarium solani, Fusarium oxysporum, Macrophomina phaseolona, Aspergillus niger and Aspergillus flavus. However, Aspergillus flavus showed maximum zone of inhibition of 8 mm for 210 microg and 7 mm for the concentration of 190 microg using well method where as the oil did not show any response against Aspergillus niger using well method:
