Indiscriminate use of synthetic chemical pesticides has led to several environmental problems such as resistance and environment pollution. Nanotechnology visualized as a rapidly evolving field has potential to revolutionize agriculture and food systems. We utilized nano-technological interventions for developing nanopesticides with potent fungicidal and miticidal properties. Nanosulphur and nanohexaconazole were prepared using encapsulation technique. The Dynamic Light Scattering (DLS) studies, Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) studies confirmed the nano-structure of nanopesticides. Nanoparticles of sulphur and hexaconazole thus characterized were estimated for the presence of active ingredient in the formulation adopting analytical techniques like Gas Chromatography / High Pressure Liquid Chromatography (HPLC). The bio-assay studies revealed many fold improved activity of nanopesticides against fungi and mites as compared to commercial sulphur.
