PREFACE
Finally the complete proceedings of the full papers presented at the
Third International Symposium of the Afro-Asian Society of Nematologists
is brought into shape and is published. It has taken me more time on
completing the same than I had thought of due to financial constraints.
However, I did not want to further prolong this period.
This book contains a vast diversity of subjects of varied interested
nematologists from all over India and few firm other countries. It depicts
well the important nematodes in our agricultural system and the loss caused
to the products.
I take this opportunity to thank all the nematologists who made it
possible to attent the symposium in spite of their busy schedule and present
these papers.
I have composed all the papers to form a single book, such that
it will be useful other nematology workers in future. It is my hope that
this book will serve to conduct future meetings and publications.
I would specially like to place on records my sincere thanks to
Dr. N. Somasekar, Dr. P. Sundara Raju, Dr. K. Sujatha Paul.
Mrs. C. Vani, Mrs. Ohara lothi, Mr. T. Kathiresan and Mrs. M. Neela
who had all helped me immensely in conducting the symposium and also
in putting this compilation into proper shape.
I would further like to thank our Director General (ICAR)
Dr. R.S. Paroda, late, Dr. B.K. Tripathi, Director, Sugarcane Breeding
Institute, for the timely help rendered to me in conducting of this international
symposium.
Also I express my deepest appreciation to all my family members
for the full support and their patience during this symposium.
