The Department of Plant Pathology was created in 1947. Dr. M. J. Thirumalachar was the first Head of the Department. He was succeeded by Dr. N. Prasad, Dr. M. K. Patel, Dr M. V. Desai, Prof. A. J. Patel. Under their capable leadership, the Department expanded to include many dedicated faculty members like, Dr. J. G. Patel, Dr. B. K. Patel, Dr. Ashok Mishra, Dr. G.B. Valand, Dr. R. N. Pandey, Dr. A.B. Brahmbhatt and many more, whose contributions made the Department as the recognized leader in the country in the field of Plant Virology, Seed Pathology, Biological control, Mushroom culture, Management of Plant diseases, etc.
 
Presently, the department is headed by Dr. R. G. Parmar and members of the Department include 4 Associate Professors, 2 Assistant Professors, 1 technical assistant and 3 supporting staffs. The entire faculty strives hard to achieve the excellence in the field of education, research and extension. The department is surging ahead with the researches in the field of Plant Virology, Seed Pathology, Biological control of Plant diseases, mushroom culture, management of plant disease, management of post harvest diseases, etc.. The department is having 11 different project viz. AICRP on NSP (Crops) Seed Technology Research & Lead centre of seed borne viruses and TSP project, State Non plan for catering the need of education and plant and pest disease management; Plan Projects on Plant virology, Biocontrol of plant disease, Mushroom culture, GSBTM project,  other agency funded projects, etc. Besides, the department has well developed art of state laboratory of plant virology, biological control, seed pathology and mushroom production. The department is producing Anubhav Trichoderma for the use of the farmers as transfer of biocontrol technology.
 

Mandate and Objectives of the Department:

  • Imparting education to under-graduate and post-graduate students.
  • Providing guidance to post graduate students for their thesis research work.
  • Counseling of U.G. students for JRF examination and P.G. students for SRF, NET, ARS and other competitive examination and personality development.
  • Conducting researches useful to the farmers and undertaking research projects sponsored by State Government, ICAR, other agencies, etc.
