Compendium of Hop Diseases and Pests is a comprehensive and authoritative account of diseases and pests of hops as well as numerous other disorders and injuries that impact this valuable specialty crop. This compendium is a practical reference for anyone interested in healthy, high-quality hops, which in addition to brewing, is showing promise for use in sugar processing and as a preservative in ethanol production and for its potential use as an antimicrobial additive in animal feed. More than 140 color images are presented with expert scientifically peer-reviewed descriptions of the identifying characteristics of disease and pest symptoms and their causal agents. This book also provides an overview of the taxonomy and botanical traits of the genus Humulus. It provides insight into cone uses and chemistry, methods for hop production, and an extensive list of hop cultivars and their characteristics. The description of each disease or pest includes a general account of its importance and world distribution, symptoms, causal organism or agent, disease cycle and epidemiology, management, and selected references. The references document the descriptions and provide resources for additional information. Compendium of Hop Diseases and Pests assists in the diagnosis of hop diseases and pests in the field, laboratory, or diagnostic clinic and provides recommendations for management of hop diseases and pests.

As well as comprehensive details of pest and disease management strategies, each chapter also includes a classification scheme for the cited pests and diseases. This important publication is a vital tool for all those involved in the crop protection / agrochemical industry including business managers, entomologists, agricultural scientists, plant pathologists and those studying and teaching BASIS courses. As an important reference guide for undergraduate and postgraduate students studying agricultural sciences, applied entomology and crop protection, copies of the book should be available on the shelves of all research establishments and universities where these subjects are studied and taught. Pest and Disease Management Handbook is published for the British Crop Protection Council (BCPC) by Blackwell Science. BCPC is a registered charity having the principal objective of promoting the development, use and understanding of effective and sustainable crop protection practice.
