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.

Bio-efficacy of Organic Formulations on Crop Production-A Review

“…Lithourgidis et al, (2007) observed that soil application of liquid cattle manure (LCM) (excrements plus urine, occasionally containing bedding material) can enhance plant growth and increase crop yield as well as increases in plant macronutrients concentration or uptake. Rakesh et al, (2013) showed that the marked inhibition of rhizome rot pathogens by cow urine extracts of selected plants. The extracts may find a possible use in agriculture as potent agents against pathogens.…”

Inhibitory Activity of <i>Polyalthia longifolia</i>, <i>Anaphalis lawii</i> and <i>Gnidia glauca</i> against Colletotrichum <i>capsici</i> and Urinary Tract Pathogens

“…In the present study, we investigated antifungal effect of extracts of different parts of P. longifolia, G. glauca and A. lawii against C. capsici isolated from anthracnose of chilli by poisoned food technique. This technique is widely used to evaluate antifungal activity of a variety of samples including plant extracts (Chutia et al, 2009;Farooq et al, 2010;Rakesh et al, 2013;Kambar et al, 2013). Extracts of P. longifolia exhibited higher inhibition of mycelial growth of C. capsici followed by A. lawii and G. glauca.…”

Antifungal Activity of Cow Urine Extracts of Selected Plants Against Phytopathogenic Fungi

“…The plant materials were dried under shade and powdered in a blender. Cow urine extraction of selected plants was carried out by using the method of Rakesh et al, [15]. with slight modification.…”

“…Inhibition of mycelial growth (%) = (C -T / C) x 100, where C and T refers to colony diameter in control and poisoned plates respectively [15].…”

“…Cow urine is shown to exhibit potent inhibitory activity against a wide range of pathogenic microbes including phytopathogenic fungi [3,4,[6][7][8][9][10][11]. Similarly, formulations based on cow urine and plants have shown to possess inhibitory effect against various pathogenic microorganisms [12][13][14][15][16][17]. The present study was carried out to investigate antifungal potential of cow urine extract of 14 plants collected from different places of Karnataka against two phytopathogenic fungi namely Colletotrichum capsici and Fusarium oxysporum f. sp.…”
