The new second edition now includes information on insects and mites with 68 images to help identify these pests and the damage they cause. The book will be an invaluable resource for serious rosarians, commercial growers, garden centers and even casual gardeners who have a special interest in growing roses.

Dr. Horst, who is considered one of the foremost experts on plant disease brings to the reader his vast experience dealing with diseases such as powdery mildew, black spot, rose canker, botrytis blight, verticillium wilt and other diseases caused by fungi. The book covers rose diseases caused by bacteria as well as viral diseases such as rose mosaic, rose streak, leaf curl and other problems. It also covers rose damage caused by physiological problems, environmental imbalances, air pollution, pesticide toxicity and nutritional deficiencies.

Published by the APS Press which is the publishing arm of The American Phytopathological Society, the new Compendium of Rose Diseases and Pests, Second Edition features:

Color photographs of infectious disease symptoms, now inset with the text, enable users to accurately identify diseases that affect roses and quickly understand the causes, life-cycles, and treatment approaches available.

Noninfectious symptoms, such as those caused by pollution and toxicities, are covered and illustrated with color photographs that help distinguish them from bacterial, fungal, nematode, and viral symptoms.

A new color section on pests and the symptoms they cause helps users to identify the insects and mites that attack roses.

Discussions of pest and disease management measures stress timeless principles and cultural practices ensuring that this reliable sourcebook will help maintain healthy rose bushes for many years to come.

A genealogy map of rose species provides a guide to the development of hundreds of rose species, along with general growing tips and practices.

The purpose of this new edition is to aid plant pathologists, entomologists, horticulturists and other related specialists as well as casual rose gardeners and rosarians, in the diagnosis of rose diseases and pests. It is designed to serve as a practical reference and resource for rose growers and gardeners, students, researchers, educators, crop disease and pest consultants, advisors in state and federal government and regulatory agencies, agribusiness representatives, the pest control industry, county agricultural and cooperative extension agents, and area crop specialists worldwide.

Authors R. Kenneth Horst and Raymond Cloyd have distinguished backgrounds in writing on diseases and insect problems associated with ornamental plants. The senior author, Dr. Horst, is professor emeritus of plant pathology from Cornell University. He has been an active educator, public speaker, researcher and writer on ornamental diseases since the early 1960s. His writing includes more than 230 publications in scientific and trade journals and several books including the Compendium of Chrysanthemum Diseases and his ongoing role as editor of Westcott's Plant Disease book.

Dr. Horst is also known for developing a number of environmentally responsible disease control products, including GreenCure(R) fungicide, a potassium bicarbonate based broad spectrum fungicide. GreenCure(R) has a proven track record in more than 200 university trials and 9 years of use by commercial and organic agricultural growers. Research that led to the development of GreenCure(R) relied extensively on testing against rose diseases.

The GreenCure(R) formula is used in commercial rose production and agriculture as well as by home gardeners for rose and ornamental growing, fruits, vegetables and turf. The benign nature of the formula enables it to be used in organic production as it meets the USDA's requirements for organic certification under the National Organic Program. This makes it an ideal fungicide for use on fruits and vegetables such as tomatoes, cucumbers, squash, pumpkins, beans, apples, grapes and many other plants.

The co-author, Raymond Cloyd, is well recognized for research and extension publications on insects or ornamental plants since the mid 1990s. He has held positions in private industry and authored a book on IPM for gardeners.
