Abstract
Objective: The leaf extract of Butea monosperma (Lam.) was evaluated in vitro for antifungal activity against six different fungal genera. Material and methods: Different concentration of leaf extract ranging from 500 to 2000 µg was used. All the concentrations exhibited varying degree of inhibition against the test fungi. Higher activity was observed with 2000 µg concentration in all six fungal organisms. Results and conclusion: The zone of inhibition ranged from 0.8cm to 2.6 cm in various fungal species and increased with the increase in the concentration of test solution. Among the test organisms, high inhibition zones were observed in Fusarium oxysporum (2.6 cm) followed by Colletotrichum capsici (1.7cm), Fusarium monoliforme (1.6 cm), Rhizoctonia solani (1.5cm). Among all, Macrophomina phaseolina (0.8 cm) and Alternaria solani (0.9 cm) exhibited lesser activity.
