Work experience

  • Scientist SS, Indian Institute of Maize Research, Rajendranagar, Hyderabad (India) from April 21, 2013 to till date.
  • Scientist, Indian Institute of Maize Research, Rajendranagar, Hyderabad (India) from May 11, 2010 to April 20, 2013.

 Area of interest

  • Host Plant Resistance, Plant Insect Interactions, and Botanicals for the management of insect pests of maize.

  Most significant achievements (in last five years)

  • Maize treated with Ageratum conyzoides leaf powder at the rate of 2% w/w stored in High Density and Double layered polythene bags suffered minimum damage by storage pest Sitophilus oryzae L.
  • Application of Tinospora cordifolia water based leaf paste between the layers of double storage bags @ 2.0% w/w reduces the level of infestation and per cent grain weight loss by oryzae.
  • Higher concentrations of cell-wall bound p-CA, ferulic acid and tannin content are the possible biochemical defense mechanisms in maize against Sesamia inferens.
