Plants are sources of nourishment for thousands of fungi, bacteria, invertebrates, vertebrates, and other plants. Plants possess a truly remarkable diversity of mechanisms to fend off attackers and recent research has shown just how complex and sophisticated these defense mechanisms can be. Plant Defense provides comprehensive coverage of the range of different organisms that plants need to fend off, describes how plants coordinate their defenses against multiple attacks, explains the evolution of defense in plants, and how plant defences are exploited in crop protection strategies. Plant Defense: Covers plants’ defenses against pathogens, pests, and parasitic plants: together in one book Brings together succinct, cutting edge information in a user-friendly format Gives an understanding of how plants ward off attacks from multiple enemies Is written by Dale Walters, an internationally known and respected researcher and teacher in crop protection, who distils his wealth of knowledge in a novel and exciting way Is an essential purchase for all those involved in plant protection around the globe Plant Defense is primarily designed for use by upper undergraduates and post graduates studying crop protection, agricultural sciences, applied entomology, plant pathology, and plant sciences. Biological and agricultural research scientists in the agrochemical and crop protection industries, and in academia, will find much of great use in this excellent new book. Libraries in all universities and research establishments where agricultural and biological sciences are studied and taught should have multiple copies of this very valuable book on their shelves.

The control of diseases in crops is still largely dominated by the use of fungicides, but with the increasing incidence of fungicide resistance, plus mounting concern for the environment resulting from excessive agrochemical use, the search for alternative, reliable methods of disease control is gaining momentum. The purpose of this important book is to examine the development and exploitation (or potential for exploitation) of a range of non-chemical approaches to disease control, with a focus on the need for a greater understanding of crop ecology as the basis for effective disease control in the field. Chapters in the book, written by international experts in the subject area, include coverage of: biological control methods host-plant resistance the exploitation of tolerance and the use of bacteriophages Carefully edited by Professor Dale Walters, widely respected for his work in the area of crop protection, Disease Control in Crops is an essential reference book for plant pathologists, microbiologists, plant and agricultural scientists and crop protection specialists, including those working within, and providing consultancy to, the agrochemical industries. Libraries in all universities and research establishments where biological sciences and agriculture are studied and taught should have copies of this timely publication on their shelves.

The survival of plants on our planet is nothing short of miraculous. They are virtually stationary packages of food, providing sustenance for a vast array of organisms, ranging from bacteria and fungi, through to insects, and even other plants. But plants are master survivors, having coped with changing environments and evolving predators over much of the history of life on earth. They have surveillance systems and defences that would put most modern armies to shame. They need to have a formidable armoury, because their enemies have sophisticated weaponry of their own. In this often hostile world, battles are fought daily, often to the death. These battles are not trivial - they matter, because life on this fragile planet of ours depends on plants. In this book Dale Walters takes readers on a journey through these battlefields, exploring how predators try to fool plants' surveillance systems and, if they manage to do so, how they gain access to the nourishment they require. Incredibly, successful attackers can manipulate plant function in order to suppress any attempt by the plant to mount defensive action, while at the same time ensuring a steady supply of food for their own survival. Walters shows how plants respond to such attacks, the defences they use, and how the attacked plant can communicate its plight to its neighbours. These skirmishes represent the latest stage in an unending evolutionary war between plants and organisms that feed on them. These battles might be on a micro scale, but they are every bit as fierce, complicated, and fascinating as the battles between animal predators and prey.

Plant diseases worldwide are responsible for billions of dollars worth of crop losses every year. With less agrochemicals being used and less new fungicides coming on the market due to environmental concerns, more effort is now being put into the use of genetic potential of plants for pathogen resistance and the development of induced or acquired resistance as an environmentally safe means of disease control. This comprehensive book examines in depth the development and exploitation of induced resistance. Chapters review current knowledge of the agents that can elicit induced resistance, genomics, signalling cascades, mechanisms of defence to pests and pathogens and molecular tools. Further chapters consider the topical application of inducers for disease control, microbial induction of pathogen resistance, transgenic approaches, pathogen population biology, trade offs associated with induced resistance and integration of induced resistance in crop protection. The book concludes with a consideration of socio-economic drivers determining the use of induced resistance, and the future of induced resistance in crop protection.
