Mycorrhizologists all over the world have been working diligently for the production of mycorrhizal fungi on a commercial scale so that these may partially replace chemical fertilizers, the use of which besides being costly, also involves environmental pollution. At present over 400 scientists are working on mycorrhizae in India and an equal number is perhaps working in other countries of Asia but communication among them has been minimal. The objective of this directory is to create a network of scientists involved in mycorrhizal research as also to identify centers and institutions in Asia particularly in India where such research is being carried on. The Directory is based on information collected through sending out forms to scientists. Although efforts will be made to identify and contact as many scientists and researchers as possible, the Directory will, by no means, be considered complete and final. It is proposed to be an ongoing activity with new additions continually updating this directory. Mycorrhizologists are requested to communicate to us through the ‘Contact’ section any change of address/CV updates. New members are encouraged to register with the Project by sending us the filled-in form appended to the Directory. Suggestions for improvement of the Directory are most welcome.
