पादप रोग विज्ञान में नैनो टेक्नोलॉजी की भूमिका Nanotechnology has valuable practices in management of plant disease in different ways; the most common is nanoparticle application on seeds and soil or leaves to protect the plants from pathogens or to control infection (Khan and Rizvi 2014). Crop cultivation is affected with number of different fungal, bacterial and viral diseases. Plant pathogenic fungi must be controlled due to increasing consumer demand in developed countries for premium quality and diverse food; while high quality cereals, fruits and vegetables are indicator of economic growth in developing countries. Commercial agriculture is heavily dependent on high inputs of chemical pesticides to protect crops against pathogens and pests. After the introduction of fungicides in 1940, the use of fungicides increased highly for controlling diseases. Due to hap hazardous use of chemicals against diseases posed danger to living system killing not only the target harmful microorganism but also beneficial living organisms. The resistance of pests and plant pathogens against pesticides and fungicides is rapidly becoming a serious problem. To preserve biodiversity, it is becoming necessary to strengthen our strategies and achieve disease management by alternate approaches such as nanotechnology (Patel et al., 2014). Nanotechnology deals with manufacturing, study and manipulation of matter at nano-scale (or atomic scale) in the size range of 1-100 nm which can be called...

कृषि मेें स्‍थायि‍त्‍व के लिए जैवसंश्लेषण नैनोकणों का महत्व  Nanotechnology is one of the most important and recent tools in modern science yet only a few attempts have been made to apply these advances for increasing crop productivity. The nanotechnology technique may be the most hopeful and reassuring way to improve the overall agricultural production. The potential applications of nanoparticles in agriculture sector include biosensors; gradual, time-consuming, and controlled delivery of chemical fertilizers and pesticides; detection and control of plant diseases; soil and water remediation; etc. At present however the use and employment of nanotechnology in the agricultural field is in the infant stage; however, if discovered gradually and used in a sustainable way, this new technology can help in the orientation of our agriculture and society today to new heights in the future. Biosynthesis of nanoparticles Preparation of nano particles can be done by using physical, chemical and biological methods. Chemical method of synthesis is more useful as it takes short time for synthesis of bulk amount of nano particles. The chemicals reagents used in chemical methods are toxic and lead to synthesis of by-products which are not environment friendly. Therefore, there is need of development of procedure which is eco-friendly and not requires any toxic material for the synthesis of nanoparticles. The methodology for nano...
