The Book Encyclopedia of Nematology contain 31 through providing chapters Covering all important and economically plant parasitic nematodes reported from India and world. We worked for almost three years to compile the book taking the help of literature available in various published data photographs and histogram. We acknowledge the sources citations in books and research papers etc. The Book is intended for graduate post graduate, students, researchers, teachers and administrators etc. as text book.
