Role of nanoparticles in management of plant pathogens and scope in plant transgenics for imparting of disease resistance
Current efforts are focused on the search for efficient methods of pathogen management that will not result in damage to environment or an imbalance in existing biota. One of the strategies for this is use of nanoparticles in agriculture for disease management. This review presents a summative view on the various applications of nanoparticles in conferring disease resistance to crops and the possibility of using nanoparticles as carriers of genetic material for generation of disease resistant crops. Nanoparticles are directly being used for the control of pathogens. Nanoparticles have been used as antiviral, antifungal and antibacterial agents. The nanoencapsulation of pesticides in controlled release matrices is one of the most promising research areas for the future. Nanoencapsulation has been shown to increase the efficiency of pesticides, reduce their volatilization and decrease toxicity and environmental contamination in crops. The nanoencapsulated agrochemicals or biomolecules can be engineered to be released in a controlled manner and in a target-specific location. Nanoparticles also have a great scope in the field of transgenics vis-à-vis pathogen resistance. The field of agriculture can be revolutionized by the use of nanoparticles for imparting disease resistance in crops. The field is so versatile that the possibilities are endless.
