The greengram is highly susceptible to Mungbean yellow mosaic virus, (MYMV) which causes 90% yield loss. The MYMV is transmitted by whiteflies (Bemisia tabaci) in a persistent manner. Most of the management strategies are through chemical pesticides as vector control. It was hypothesized to control whiteflies with a good alternative to pesticides. In this study, Azadirachtin loaded in silica nano particle and Annosquamosin plant biomolecule were studied for its efficacy against Bemissia tabaci. Azadirachtin loaded in silica nanoparticles at 500ppm showed cent per cent mortality of adult Bemisia tabaci followed by 90% mortality in Annosquamosin extract at 5 hrs of incubation. Thus, Azadirachtin loaded in silica nanoparticles can be used as a better alternative to the highly toxic chemical pesticides.
