While many books are available on biological control, this is the only book to detail the application of molecular biology to control of pests and diseases. Each chapter deals with a different pathogen and the application of new molecular biological techniques to the biocontrol of the pathogen. This new reference presents the most comprehensive list of organisms available. Internationally respected experts discuss viruses, bacteria, fungi, nematodes, protozoa, weeds, and insects. Types of control methods are described, and techniques commonly used in molecular biology to identify the etiological agents, diagnose diseases, and develop control methods are reviewed.
