Inhibitory Effect of Cow Urine Extracts of Selected Plants against Pathogens Causing Rhizome Rot of Ginger

Abstract

The present study was carried out to investigate the inhibitory effect of cow urine extracts of nine plants against two fungi viz., Fusarium aphanidermatum and a bacterium Ralstonia solanacearum rhizome rot of ginger. Antifungal and antibacterial activity of cow urine extracts was investigated by poison food technique and agar extent of growth of test fungi in plates poisoned with extracts was lesser when compared with the control plates. Among fungi, high susceptibility was recorded in case of oxysporum. Cow urine extract of Elaegnus k aphanidermatum whereas cow urine extract of Croton roxburghii and Maesa indica caused high inhibition of caused inhibition of R. solanacearum. Extract of followed by H. indicus, E. kologa and others. Overall, cow urine extracts of plants selected in this study caused varied inhibition of test microbes. These extracts may find a possible application in agriculture against phytopathogenic microorganisms.
