The common diseases of more than 150 popular perennials are included in this book, arranged alphabetically by plant and accompanied by hundreds of fine color photographs to assist in accurate disease diagnosis. Short descriptions of the cultural conditions that will help these plants remain healthy and thrive are given for each host plant. Tips are provided to assist growers and gardeners in managing challenging diseases.

The aim of this book is to help readers to recognize the major diseases of herbaceous perennial ornamentals and to manage them effectively. It will be valuable to commercial plant producers and retailers, landscape managers, professional, home, and master gardeners, and the many advisors and extension professionals that serve the green industry. Professional plant diagnostic labs, plant health inspectors, and plant industry salespeople will find this book an essential aid for properly identifying new plant diseases such as downy mildew on rudbeckia, as well as the classic plant problems such as Botrytis blight on peony. To assist those new to the concepts of plant disease, supplementary information is included on the different kinds of micro-organisms that can cause contagious plant problems. References are provided for further reading and a glossary is available to help readers understand unfamiliar terms. Anyone who loves perennials will be able to use this book.
