英文摘要 | In Indian arid region, soil borne plant pathogens causes root rot and wilts in economically valuable plants. Eco-friendly management options were developed in order to avoid dependence on expensive and hazardous chemical means of control. In rain fed agriculture, amendment of soil with composts prepared from residues of on farm wastes was found effective in reducing incidence of Macrophomina phaseolina induced charcoal rot on legumes. In field, least plant mortality due to charcoal rot on guar (Cyamopsis tetragonoloba (L.) Taub.) was recorded in weed and Prosopis juliflora (5.5-6.7%) compost amended plots compared to 16.6% in non amended control. Beneficial effects were also discernible in yield promotion by 39.9% in P. juliflora compost amended plots. In irrigated agriculture, polyethylene mulching for 15 days elevated the soil temperature by 2.5-13.1 degrees C compared to non mulched plots, resulting in 70.4-100% and 69.3-94.7% reduction in viable propagules of M. phaseolina and Fusarium oxysporum f. sp. cumini, respectively. This reduction was reflected in reduced incidence of root rot on guar and wilt on cumin (Cuminum cyminum L.). As an alternative to soil solarization, Brassica amendments were found effective in reducing population of soil borne plant pathogens with additional benefit in the form of enhanced population and activity of native bio control agents like Bacillus firmus and Aspergillus versicolor. Technological interventions of these strategies singly or in integrated manner at farmers' field for management of these diseases has produced encouraging results. |
