  • Coverage on most diseases and pests affecting hop throughout the world which is helpful when analyzing a new disease introduced to a specific region
  • A useful broad reference for home brewers particularly those interested growing their own hop. This compendium contains sections on hop taxonomy, chemistry, and production with an extensive listing of hop cultivars and their characters.
  • Identify growth abnormalities that are not caused by plant pathogens or insects with expert descriptions and color photographs of symptoms of nutrient disorders and plant injury.

Compendium of Hop Diseases and Pests is a comprehensive and authoritative account of diseases and pests of hop 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 hop, 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. This compendium will be useful to plant pathologists, entomologists, nematologists, crop production specialists, growers, diagnostic clinicians, students, regulatory agents, crop consultants, agribusiness representatives, educators, researchers, and others interested in the recognition or management of hop diseases and pests throughout the world.
