The term 'nano' (Greek word) mean dwarf. Nanometre (nm) is one-billionth of a metre, or approximately one hundred thousandth of the width of a human hair. Nanotechnology, the fascinating science refers to the technology of rearranging and processing of atoms and molecules to fabricate materials to nano specifications such as a nanometre (1-100 nm). A key requirement in the area of nanotechnology is the growth of reliable and environment friendly process for synthesis of metallic nanoparticles. Synthesis and characterization of noble metal nanoparticle like silver with unique electronics, optical, magnetic and chemical properties, which differ considerably from those of the corresponding bulk material is a challenge and are technological importance. In our study we synthesized silver nanoparticle from different potential biological sources, which were characterized by UV-VIS spectrophotometer, DLS, XRD, TEM and Zeta potential. The green synthesized silver nanoparticle when tested against different plant pathogens like, Rhizoctonia solani, Sclerotium rolfsii, Fusarium spp., Sclerotinia sclerotiorum, and Colletotrichum capsici, we found silver nanoparticle at 100 ppm have higher antifungal efficacy as compared to the recommended chemical. In our laboratory, works on green synthesis of nanoparticle like zinc oxide, copper, gold and chitosan, their efficacy against different plant pathogens and preparation of nanobioformulation is in progress. If these are found effective it will pave the way of using green synthesized nano particle for plant disease management. This will also reduce the pressure of pesticide load in the environment to the extent of many fold. Scientists have developed interest towards exploring new applications of nanotechnology in agriculture and the food industry too- if these discoveries applied wisely, the environment, the agricultural sector and the food industry will indeed see remarkable change for the superior in the forth coming years.
