19 Jun Ecofriendly management of soil borne plant pathogens in arid region
शुष्क क्षेत्रों में मिट्टी से पैदा होने वाले पौध रोग जनकों का पर्यावरण हितैषी प्रबंधन Crops of Indian arid region suffer heavily every year due to biotic stresses caused by soil born plant pathogens. These pathogens remain viable in soil as a dormant propagules and control of these pathogens by chemical means is not economical and also not advisable due to environment concerns. Management of these pathogens through eco-friendly approaches have been discussed here that provides long term benefit to the farmers for sustainable development of arid crops. Soil borne plant pathogens like Fusarium spp., Macrophomina phaseolina etc. causes severe yield losses in major arid land crops like Cumin, Pearl millet Clusterbean, Mungbean etc. Mono-cropping of these major crops facilitates the build-up of population of these soil borne plant pathogens. Once these pathogens get established in the soil eco-system it becomes very difficult to eradicate because they can survive for several years by producing dormant propagules in the soils. Complete eradication of these soil borne plant pathogens by chemical means is not feasible and it requires huge amount of energy and chemicals which ultimately pollute the environment and also create imbalance in the eco-system. Use of chemicals for the management of diseases require availability of water in ample quantity for spray or for...
