Economically Important Plant Parasitic Nematodes Distribution ATLAS

The existence of nematodes known for 4 billion years has contributed for their rich biodiversity, prevalence, occurrence and distribution under varied agro-eco-systems. The All India Coordinated Research Project (AICRP) on Plant Parasitic Nematode with Integrated Approach for their Control, a discipline oriented project, has generated quite useful information on distribution of economically important nematodes under different agro-climatic zones of the country through extensive and intensive nematode surveys carried out by different cooperating centres associated with the project in last 3 decades. One of the objectives of AICRP on Plant Parasitic.

Nematode with Integrated Approach for their Control has been to map out the distribution of nematodes on different crops and to place the scattered information in one spine. Hence, efforts were made to include information generated through cooperating centres of AICRP on Plant Parasitic Nematode with Integrated Approach for their Control as well as those provided by the Nematologists working in crop-based institutes of the ICAR to depict this information as an Atlas. In the present Nematodes Distribution Atlas, economically important nematode species associated with different crops have been depicted on national map at a glance as well as on the state maps showing nematode-wise distribution in different districts of the State. In addition, information on physiography, agro-climatic zones, major nematode problems of the crops with economic importance and technologies developed so far for their management through AICRP on Plant Parasitic Nematodes with Integrated Approach for their Control has also been included for ready reference. In this Nematodes Distribution Atlas, the information belonging to Asom, Madhya Pradesh, Gujarat, Haryana, Himachal Pradesh, Karnataka, Kerala, Maharashtra, Orissa, Rajasthan, Tamil Nadu, Uttar Pradesh and West Bengal where AICRP on Plant Parasitic Nematode with Integrated Approach for their Control centres are located has been included. However, the distribution of economically important nematodes with respect to Tripura, Meghalaya, Manipur, Arunchal Pradesh, Nagaland, Bihar, Jharkhand, Andhra Pradesh, Jammu and Kashmir, Punjab, Goa, Delhi and Uttrakhand needs to be completed in the next phase. This is a maiden attempt to present the information generated through the project as Atlas, which can be further updated periodically
