Popis: The present study was carried out to investigate the inhibitory effect of cow urine extracts of nine plants against two fungi viz., Fusarium oxysporum f.sp. zingiberi, Pythiumaphanidermatum and a bacterium Ralstonia solanacearum that are known to cause rhizome rot of ginger. Antifungal and antibacterial activity of cow urine extracts was investigated by poison food technique and agar well diffusion method respectively. The 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 F. oxysporum. Cow urine extract of Elaegnus kologa caused high inhibition of P. aphanidermatum whereas cow urine extract of Artocarpus lakoocha, Hemidesmus indicus, Croton roxburghii and Maesa indica caused high inhibition of F. oxysporum. All extracts caused inhibition of R. solanacearum. Extract of A. lakoocha caused maximum inhibition 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.
