Among the various pests and diseases that damage crops, plant parasitic nematodes present a formidable pest problem for different crops. Most species attack and feed on plant roots and underground plant parts. However, a few species attack the aerial plant parts also. Role of plant parasitic nematodes in agricultural production has remained underestimated due to their soil-borne nature, microscopic size, hidden mode of life and non-typical insidious feeding symptoms on the plants. The enormous economic damage to plants by their root feeding and interactions with other organisms renders the plants further vulnerable to other biotic and abiotic stresses.
In view of damage potential of these tiny hidden enemies of crop plants, an urgent need was felt for initiating coordinated efforts at national level pertaining to nematode distribution, assessment of crop losses and for developing nematode management technologies. Therefore, the Department of Science and Technology, Government of India, initially launched the "All India Coordinated Research Project (AICRP) on nematode pests and their control" w.e.f. April 1, 1977 with 11 centers besides a Coordinating Cell at the Division of Nematology, I.A.R.I. Indian Council of Agricultural Research took it up w.e.f. April 1, 1979 as a Plan project. The title of the project was modified during VII Five Year Plan as "AICRP on Plant Parasitic Nematodes with Integrated Approach for their Control".
The Project Coordinating Cell functions from Division of Nematology, I.A.R.I. Presently, the project has 18 cooperating centers located at different agro-climatic zones. These are - Anand Agricultural University, Anand; Assam Agricultural University, Jorhat; Bidhan Chandra Krishi Vishwavidyalaya, Kalyani; Choudhary Charan Singh Haryana Agricultural University, Hisar; Chandra Shekhar Azad University of Agriculture & Technology, Kanpur; Choudhary Shravan Kumar Himachal Pradesh Krishi Vishwa Vidyalaya, Palampur; Jawahar Lal Nehru Krishi Vishwa Vidayalaya, Jabalpur; Kerala Agricultural University, Vellayani; Maharana Pratap University of Agriculture & Technology, Udaipur; Mahatma Phule Krishi Vishwavidyalaya, Rahuri; Orissa University of Agriculture & Technology, Bhubaneswar, Tamil Nadu Agricultural University, Coimbatore; and University of Agricultural Sciences, Bengaluru. Five new centers were added during XII Plan, these are – Sardar Vallabhbhai Patel University of Agriculture & technology, Meerut; University of Agricultural & Horticultural Sciences, Shivamogga; Sri Karan University of Agriculture, Jobner; Central Agricultural University, Imphal; and National Institute of Biotic Stress Management, Raipur. One voluntary center – Indian Statistical Institute, Kolkata was added subsequently. Addition of some more voluntary centers is on the anvil.
