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 were 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 in a CSompletely Randomized Design. In A. vera acetone extract, first day after inoculation, inhibition percentage of the Marasmiellus spp was higher (74.53 %) in 2000 μL and the lowest percentage (23.53 %) of inhibition was obtained in 20 μL of A. vera acetone extract. The similar highest and lowest percentage of inhibition were observed in second, third and fourth day after inoculation. In A. vera ethanol extract, complete (100 %) inhibition was observed in 1000 μL and 2000 μL extracts. The lowest inhibition (2.26 %) was recorded in 20 μL of A. vera ethanol extract. Among the 1000 μl and 2000 μL leaf extracts, ethanol extract had the highest inhibition percentage compared to A. vera acetone extract. These findings are useful to prepare the extracts of A. vera leaf powder for the management of Marasmiellus spp.
