Abstract

Increase of agricultural yield by sustainable intensification has attracted wide attention, as it has no adverse environmental impact. Hereby, alternative strategies to control pests and diseases in crops have combined nanotechnology with other disciplines like biotechnology, horticulture, genetic engineering and microbiology. Novel inorganic-, polymeric- and lipid-based nanomaterials are being explored for designing nanofertilizers, nanopesticides, nanoweedicides and nanoherbicides. The physical and chemical techniques used for fabrication of such nanoformulations often use hazardous and toxic chemicals that adversely affect the environment during field applications. Hence, biogenic nanoparticles have become an attractive alternative as they follow an environmentally benign economic route for synthesis. Hence, this chapter gives an elaborate account of various biogenic nanoparticles synthesized by bacteria, fungi and plants for control of phytopathogenic bacteria and fungus. The mechanism of synthesis and crop protection has been discussed in detail. Eventually, further research to develop functionalized biogenic nanoparticles for crop protection and preservation is presented as a powerful strategy towards sustainable agriculture.
