Features of the new Compendium of Rose Diseases and Pests, Second Edition

• 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 plants for many years to come.
• A genealogy map of rose species provides a guide to 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 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.
