Abstract:
Being an important medicinal plant, Aloe vera is important in industrial perspective as well as traditional usage. The antifungal activity of A.vera leaf powder extracts was assessed against banana pseudostem rot fungi, Marasmiellus spp. Leaf powder with acetone and ethanol extracts of 20, 200, 400, 1000 and 2000 μl were administered to assess the inhibition of colony growth of Marasmiellus spp. The experiment was conducted using completely randomized design. By using A.vera acetone extract, in first day after inoculation, inhibition percentage was higher (74.53%) in 2000 μl and the lowest percentage (23.53%) of inhibition was obtained in 20 μl of extract. All treatments were significantly differed each other. The same highest and lowest percentage of inhibition was obtained in second, third and fourth day after inoculation also. In A.vera ethanol extract, the highest (100%) inhibition was observed in 1000 μl and 2000 μl extracts. The lowest inhibition was recorded (2.26%) in 20 μl of A.vera ethanol extract. There was no significant difference between 1000 and 2000 μl extracts. Among the 1000 and 2000 μl leaf extracts, ethanol extract had highest inhibition percentage than A.vera acetone extract. These findings are useful to prepare the extracts of A.vera leaf powder for the management of Marasmiellus spp.
