Abstract

The antifungal activity of aq., petroleum ether, benzene, chloroform, methanol and ethanol exts. and alkaloid ext. of Prosopis juliflora (Sw.) DC. leaves (Mimosaceae) was evaluated for antifungal activity by poisoned food technique against Alternaria alternata a causal organism of brown spot of tobacco. Aq. ext. recorded highly significant antifungal activity at 24% concn. Among different solvent exts. tested, methanol and ethanol ext. recorded highly significant antifungal activity. Methanol ext. was further subjected to fractionation guided by antifungal activity leading to the isolation of alkaloid ext., which was also recorded highly significant antifungal activity against the test fungus and the min. inhibitory activity was recorded at 1000 ppm. The antifungal activity of alkaloid ext. was compared with synthetic fungicides viz., blitox, captan, dithane M-45 and thiram at their recommended dosage of 2000 ppm indicating that the alkaloid ext. was highly effective even at the dosage lesser than the synthetic fungicides.
