The present book discusses the biosynthesis and characterization of silver nanoparticles and evaluation of their antimicrobial activities against plant pathogens. The field of nanotechnology is one of the most active areas of research in modern materials science having diverse application in various fields. Nanotechnology is gaining tremendous impetus in the present century due to its capability of modulating metals into their nanosize, which drastically changes the chemical, physical and optical properties of material. Plant pathogens and pests are of the major factors limiting crop...

The present book discusses the isolation and genetic diversity analysis of Rhizobia from chickpea (Cicer arietinum L.). Indiscriminate use of synthetic fertilizers has led to contamination of the soil, polluted water basins, destroyed micro-organisms & friendly insects, making the crop more prone to diseases and most importantly reduced soil fertility. Bacteria of family Rhizobiaceae are symbiotic and effectively convert atmospheric nitrogen which is utilized by the host and internationally been accepted as an alternative source of chemical fertilizer. The long term use of bio-fertilizers is...
