Abstract
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.
