About Dr.Jonnalagadda S Prasad

Survey and identifying parasitic nematode problems and endemic areas for parasitic nematodes in rice and rice based cropping systems. Recommending suitable nematode management measurers in problem areas.


  • Developed a novel seed treatment method for salvaging rice germplasm infected with white tip nematode Aphelenchoides besseyi.
  • Lead cereal nematode research program of AICRP (Nematodes) as group leader resulting in identification of resistance sources and management technologies for rice nematodes.
  • Identified and evaluated entomopathogenic nematode isolates effective against rice pests.
  • Monitored the population dynamics and biology of the important nematode species in rice.
  • Identification of sources and nature of resistance to nematodes in rice and developed of screening techniques to nematodes.
  • Identified several rice genotypes resistant to root-knot nematode Meloidogyne graminicola.
  • One brinjal cultivar resistant to root-knot nematode was registered with NBPGR, New Delhi
  • One bacterial culture isolated from entomopathogenic nematode was deposited with IMPTECH, Chandigarh
  • Imparting training to the specialist trainees and subject matter specialists form the states in India
