Antifungal efficacy of caesalpinia bonducella (L.) fleming against phytopathogenic fungus macrophomina phaseolina (TASSI) gold

Caesalpinia bonducella (L.) fleming is valuable herb remedial plant. The current work was conducted to evaluate the antifungal properties of C. bonducella In vitro and In vivo against Macrophomina phaseolina (tassi) gold by food poison technique. In vitro, antifungal properties of the leaves extract of C. bonducella in different solvents viz. aqueous, ethanol, and hexane at concentrations of 5, 10, 15, and 20% was analysed. The data disclose that an increased concentration of leaves extract suppressed pathogen growth. Among all the solvents, the highest antifungal activity was obtained in an aqueous extract at 20% concentration followed by ethanol extract at 15 and 20%. In vivo, to evaluate the antifungal activity of C. bonducella, pot experiments were performed. The obtained data showed that aqueous extract of C. bonducella leaves significantly lowered the colonization% of M. phaseolina in artificially infested seeds of the castor plant (Ricinus communis L.) and promoted plant growth as compared to the control. The finding of the present studies evaluated that, the antifungal efficacy of C. bonducella was effective in the management of the phytopathogenic fungus M. phaseolina in both In vitro and In vivo conditions.
