Of information on the biology, description, distribution, detection, and management of cone and seed diseases in Canada, Mexico and the United States. Disease distribution maps are included for most major hosts and wherepossible, those diseases that occur or are likely to occur in seed orchardswhich will supply most of the future seed needs are pointed out. Eachsection gives the life history, symptoms, signs, damage, and distribution onvarious hosts of the major cone and seed diseases, with distribution mapsincluded for both hosts and diseases. A table of cone and seed diseases ofminor importance gives information on diseases whose importance is not yetwell documented. A glossary is also included, as well as lists of diseasehosts by common and scientific names.

Producing Christmas trees is big business. Every year, growers in the United States and Canada deliver 30 to 40 million trees to consumers, earning $2 billion in revenue. Growers in Europe produce an additional 110 million trees, earning $1.64 billion. To prepare for future crops, growers also plant up to three times as many trees as they harvest every year. Bringing each crop to market involves years of intensive management. The critical information needed to manage diseases and disorders of all types of conifer trees is provided in Compendium of Conifer Diseases, Second Edition. Written by 102 experts from 18 countries, this new edition presents the modern world of forest pathology. Forests today grow under increasing stress from an ever-growing human population, newly identified and invasive species of pathogens, and a changing climate. And since publication of the first edition of this compendium in 1997, diagnostic tools have evolved considerably, enabling more precise identification of pathogens, greater understanding of population genetics, and better understanding of evolutionary relationships among various species. All of these factors are addressed in the new compendium.

Diseases of Trees and Shrubs is a comprehensive pictorial survey of the diseases of, as well as the environmental damage to, forest and shade trees and woody ornamental plants in the United States and Canada. An authoritative reference, it is also a reliable and handy diagnostic tool that will simplify the identification of specific plant diseases by focusing on signs and symptoms that can be seen with the unaided eye or with a hand lens. This long-needed book gives readers complete, up-to-date information in an easily understood and convenient way. Each of the 247 color plates faces a page of explanatory text covering the biology and ecology (including host and geographic ranges) of the disease-causing agents (pathogens), a list of key references (there are more than 2,250), and, in some cases, black-and-white illustrations of pathogens. Selected information about biological and cultural control is provided. Scientific terms other than Latin names of pathogens are used only when necessary, and a glossary of terms and a comprehensive index are included. The color plates contain more than 1,700 illustrations of the diseases and injuries that some 350 biological agents and environmental factors cause to more than 250 species of plants. The book also serves as a guide to hundreds of other diseases related to those shown. The authors have used three levels of organization for this book. At the first level, diseases caused by biological agents are separated from those caused by environmental stimuli. At the second level, most diseases are grouped according to the plant part affected: leaves, twigs, limbs, roots, trunks, or the entire plant. At the third level, diseases are presented according to the taxonomic relationships among the pathogens. For this major project, the authors examined and photographed diseases and environmental damage in the field, visiting more than 50 states and Canadian provinces. Their book reflects the most important developments in fungal biology and taxonomy, plant bacteriology, virology, and environmentally induced stress in plants. It summarizes information about newly discovered diseases and provides up-to-date accounts of olds ones. Diseases of Trees and Shrubs can be profitable reading for anyone whose technical training does not extend beyond general biology, yet will also be informative to advanced students and plant pathologists. It will be welcomed by agricultural and horticultural advisers, plant inspectors, arborists, nursery professionals, landscapers, foresters, and urban planners. Wayne A. Sinclair is a Professor of Plant Pathology, Howard H. Lyon is Biological Photographer (retired), Department of Plant Pathology, and Warren T. Johnson is Professor of Entomology, all at Cornell University.
