Nanotechnology is the promising tool to improve agricultural productivity though delivery of genes and drug molecules to target sites at cellular levels, genetic improvement, and nano-array based gene-technologies for gene expressions in plants and also use of nanoparticles-based gene transfer for breeding of varieties resistant to different pathogens and pests. The nanoparticles like copper (Cu), silver (Ag), titanium (Ti) and chitosan have shown their potential as novel antimicrobials for the management of pathogenic microorganisms affecting agricultural crops. The nanotechnologies can be used for the disease detection and also for its management. The progress in development of nano-herbicides, nano-fungicides and nano-pesticides will open up new avenues in the field of management of plant pathogens. The use of different nanoparticles in agriculture will increase productivity of crop. Development of green nanotechnology is creating interest of researchers towards eco-friendly biosynthesis of nanoparticles. The synthesis of nanoparticles has become the matter of great interest in recent times due to its various advantageous properties and applications in various fields. Though chemical methods are costly, toxic and potentially dangerous to the environment. But biological approach of synthesis nanoparticles is eco-friendliness, cheap, low energy and time efficient. This reports the potential of plants i.e., “green chemistry” to synthesize nanoparticles not only in the laboratory scale but also in their natural environment.
