Srinivasa Rao M.


Applied Research: Developed sustainable integrated nematode and disease  management strategies in vegetable crops such as tomato, brinjal, onion, okra, capsicum, carrot, cauliflower cabbage,  banana, papaya, acid lime, carnations, gladiolus, tuberose and gerbera.  

Basic Research:  

Worked out the molecular basis for the mode of action of Pseudomonas fluorescensTrichoderma viride and biochemical basis of Bacillus subtilis induced systemic resistance mechanism in capsicum. Developed mass production protocols of effective bio-pesticides such as   Paecilomyces lilacinus – 1% W. P., Pochonia chlamydosporia – 1% W. P., Pseudomonasfluorescens – 1% W. P., Trichoderma harzianum – 1% W. P.  & Trichoderma viride – 1.5% W. P. and they have been registered by Central Insecticide board and Registration Committee (CIB&RC), Ministry of Agriculture.

Transfer of Technology:  Transferred the integrated nematode  and disease management technologies among the  farmers in most of the states of India through All India Co-ordinated Research Project.

Commercialization of technologies:  Technologies of mass production of bio-pesticides (IIHR - Paecilomyces lilacinus – 1% W. P., IIHR - Pochonia chlamydosporia – 1% W. P., IIHR -Pseudomonas fluorescens – 1% W. P., IIHR – Trichoderma viride – 1.5% W.P. & IIHR -Trichoderma harzianum – 1% W. P.. ) have been transferred to industries in India till date.

  9. Consortia of Trichoderma viride, Pseudomonas fluorescens and Paecilomyces lilacinus
  10. Liquid formulation of Bacillus subtilis – 1% A.S.)
  11. Liquid formulation of Pseudomonas fluorescens – 1% A.S.
  12. Arka - Tricorich (Organic formulation of Trichoderma harzianum)
