Synopsis The Management of crop diseases has become important throughout the world. Various methods have been advocated to manage viral, bacterial, fungal and nematode diseases of various crops. The emphasis and prime importance is given on the development of resistant varieties and now it has been possible to manage the various diseases in integrated manner. But the failure of resistant gene in a variety sometimes has been observed and hence the scientists are busy to manage the diseases to biotechnological manners. The biotechnology and molecular biology has found to be of great help and developing transgenic varieties in addition to regular hybridizations. The volume on biotechnological approaches for the integrated management of crop diseases will be great help to solve the problems of crop disease management. The volume consists of 26 review articles on biotechnological approaches by very well known international scientists throughout the India on different crops. Almost all the renowened institutes of ICAR, IARI, ICRISAT and other universities have contributed to make this volume success in the supplying the biotechnological approaches for the management of crop diseases. This volume is published in the honour of Prof. L.V. Gangawane who has contributed much in the management of Various crop diseases.
