Department of Plant Pathology and Nematology

About the Department

About the Department of Plant Pathology:

The Plant Pathology Department owes its origin to Imperial Agricultural Research Institute at Pusa, Bihar in 1905.  Scientists like E. J. Butler “Considered as Father of Modern Plant Pathology” in India. After the establishment of Rajendra Agricultural University in 1970, the post graduate studies in Plant Pathology started with a full fledged laboratory and staff/students.  Eminent scientist like Dr. A. P. Mishra, Dr. P. P. Mehta, Dr. M. Mahmood, Dr. G. S. Dubey, Dr. K. L. Ojha, Dr. M. M. Jha and others gave their important contribution in present status of the department.  Former Rajendra Agricultural University, Pusa has been upgraded into Central Agricultural University in the year 2016 and named as Dr. Rajendra Prasad Central Agricultural University.  Presently, Plant Pathology Department is in Post Graduate College of Agriculture with qualified teachers/scientists.

At present the Department has the intake capacity of 15 (2 in-service) students in Master degree and five students (2 in-service) in Ph. D programme.  Research, Teaching and Extension activities are running in Plant Pathology Department in full swing to fulfil the requirements of researchers, students, seed growers and farmers.

About the Department of Nematology:

The Degree in M. Sc. (Ag.), Nematology was initiated in the year 1982 with the following objectives:

  • To prepare the human resource for the researches and teaching in Nematology
  • To do the researches in different crops, like vegetables, pulses, fruits, field crops and oilseeds in which the nematodes play a major role in causing 10-12 % losses on an average.
  • To manage the diseases caused by nematodes directly as well as indirectly by inviting the secondary pathogens like bacteria and fungi increasing the disease intensity.
  • Making aware the farmers and agriculture officials through different media about the nematode problems and the diseases they cause and also the eco friendly management of those nematodes
