In the current situation several types of synthetic pesticides are available but they are harmful for the ecosystem and do possess a devastating impact on human health. The other side organic fungicides and biocontrol agents are also accessible in the market which relies on specific environmental conditions and can be used only under particular situations. Most of the organic methods are slow and time-consuming processes and contrary farmers don't have time as biological processes of the plants are fast, so the timing is foremost valuable for economic yields. To combat the existing situation there is an alternate solution exists in the form of nano technology for the management of plant pathogens and currently nano fungicides i.e., AgNps, CuNPs, TiO 2 , chitosan nanoparticles and nano emulsions are being used in the sector of plant diseases management. These days' nanoparticles are used in the agriculture sector because of their antifungal, antibacterial and antiviral properties. Nano silvers (silver nanoparticles) and nano sensors are applied against abiotic stresses and insect pests as fertilizers, growth promoters and insecticides respectively. Presently many researches were conducted on silver particles and silver nano-based fungicides show high effectivity against plant pathogens. Hopefully in the future, silver nanoparticles will be marketed for the control of plant diseases and insect pests and for the detection of pesticides. Therefore, this manuscript addresses all the possible applications and approaches of nanoparticles as effective and ecofriendly tools imparting growth to the plants which reduces impact of plant diseases on plant part as plant system is strengthen and to combat against plant pathogens & insect pests because of their antifungal, antibacterial, antiviral & insecticidal properties.
