Bio Pest Management
About this eBook
Preface The pests viz. insects, pathogens and nematodes have been causing enormous losses to the crops amounting to 20-30 as per estimates given so far in the country. Realizing the role of these pests as limiting factors in crop productivity, several methods were developed and incorporated into management modules for economically important pests. Out of these use of pesticides could initially catch up to the growers because of their ready availability and ability to suppress pest s population quickly. The indiscriminate use of these pesticides has resulted in serious damage to non-target animals including human beings. Not only this the environmental cost of pest management on account of pesticides uses become too high. Efforts are therefore, being made to search the alternative management strategies using naturally occurring macro and micro organisms. Bio-ecological management of pests using entomopathogenic nematodes is gaining popularity day by day as it has long term effect without any harmful effect on non-target organisms. In view of the importance of entomopathogenic nematodes along with other bio-agents such as parasitoids, predators and pathogens, the management strategies of pests of agricultural importance could be formulated to safeguard ecological balance and crop health. The topics on various subjects pertaining to biological eco-safe management presented by eminent scientists of the country in ICAR sponsored Summer School on Advances in Entomopathogenic Nematodes, Microbes and Bio-agents for Eco-safe Management of Pests of Agricultural Importance organized in Department of Nematology, Rajasthan College of Agriculture, MPUAT, Udaipur are arranged in a systematic manner in this book which would be of great utility to the readers and also to the planners. The authors are thankful to Dr. B. S. Yadav, Ex. Professor Head, Department of Nematology and Dr. H N. Gour Prof. Head, Department of Plant Pathology, RCA, Uadipur for regular encouragement and timely technical guidance. Thanks are also due to Dr. Sanjay Kumar Sharma, Mr. Ajay Maru and Mr. Aseem Shankar SRFs in the department for extending the desired help as and when needed.

About the book Insects, pathogens, nematodes and plants have co-existed for nearly about 400 million years. Since then the above pests have been causing enormous losses to the plants amounted to 20-30 losses as per estimates given so far in the country. Realizing the role of these pests as limiting factor in agricultural productivity, several control methods were developed and incorporated into management program for economically important pests. Out of these, use of insecticides could initially catch up to the growers because of their ready availability, ability to suppress pest s populations quickly and increasing productivity. Their use in the past was intense in areas where the thrust was on increasing agricultural productivity and also in those regions where certain crops were introduced in new agro-ecosystem. However, in most instances, their use proved to be a short-term solution rather than a long-term strategy. Pesticides are equally hazardous to livestock, plants and also to the beneficial fauna and flora.
