Of the 40-plus books produced in the popular APS PRESS Compendium of Plant Disease Series, Compendium of Apple and Pear Diseases and Pests, Second Edition, is the biggest ever and among of the most comprehensive. Nearly double the size of the previous edition, it boasts a total of 343 color images and more figures than any other compendium to date, offering second-to-none diagnostic coverage of these two important crops.

Of the many changes in this second edition, the most notable may be the addition of a new section that includes coverage of insects and mites, also known as arthropods. This section alone features 90 species and 160 color images which make this handbook a cross-disciplinary reference and scouting guide that will be utilized by extension professionals and the growers they serve for years to come.

All the original disease chapters of the first edition published in 1990 have been revised, many extensively, and 11 new chapters have been added. All chapters include the latest information on the distribution, biology, identification, and management of the many diseases and arthropod pests that occur worldwide.

This colorful guidebook is essential for ensuring early detection of disease and insect symptoms in order to implement control measures to maximum yields and product quality. It is an invaluable resource for anyone involved in healthy apple and pear production, including plant pathologists, entomologists, pomologists, extension agents, master gardeners, horticulturists, IPM practitioners, pesticide applicators, agrochemical professionals, private consultants, and growers.

The book is easy to use. It allows users to match the symptoms and pests on their trees with the book's color photographs. Users can then refer to the corresponding text which describes the related symptoms, causes, cycles, and control practices for the particular disease, insect, or mite. The authors also describe nutritional and postharvest disorders of apples and pears and provide recommendations to minimize or improve these issues.

Collectively the authors of this comprehensive work represent 12 countries and the editors have over 120 years’ experience in studying the biology and management of diseases and arthropod pests of apples and pears.
