22 Apr Role of Nanotechnology in Plant Pathology

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...
