Compendium of Alfalfa Diseases and Pests, Third Edition, is the most comprehensive diagnostic reference guide to date on the many diseases and insect pests of alfalfa, one of our most important forage crops. This easy-to-use book includes comprehensive diagnostic and management information on nearly 50 infectious diseases, noninfectious diseases, insect pests, and abiotic conditions (such as herbicide injury).
This third edition, written by more than 55 expert plant pathologists and entomologists working on alfalfa, delivers an almost entirely new collection of nearly 250 color images, along with revised management information, new coverage of five recently discovered diseases, and a new section on arthropod pests. Some pests can significantly decrease yield, and this new section describes and illustrates their life cycles, behaviors, and damage symptoms and recommends management practices.
Compendium of Alfalfa Diseases and Pests, Third Edition, is an essential resource for researchers and practitioners worldwide. Extension scientists, consultants, field staff, and growers will all find the book helpful for identifying and managing alfalfa diseases, pests, and disorders. Plant pathologists, entomologists, and technical staff in laboratories, diagnostic clinics, and regulatory agencies will find this book to be an invaluable reference.
This book is organized into three parts:
• Part I addresses the commonly occurring infectious fungal diseases of alfalfa, grouped by leaves and stems, lower stems and crowns, and crowns and roots. This section also provides information on bacterial and mollicute diseases, diseases caused by viruses, and diseases caused by nematodes. The parasitic flowering plant dodder is also discussed.
• Part II covers arthropod pests, detailing their life cycles, damage caused, identifying features, and management. This section describes arthropods that feed on foliage, including many kinds of aphids and caterpillars, crickets, grasshoppers, leafminers, plant bugs, spittlebugs, and weevils. Root pests and seed pests are addressed in special sections, as is a livestock pest, the blister beetle.
• Part III, titled “Noninfectious Diseases and Abiotic Conditions,” discusses the effects and management of genetic variations and abnormalities, herbicide injury, and injuries caused by high temperatures, flooding, nutrient deficiencies and toxicities, foliar freeze, and winter conditions.
The appendix presents an updated list of common names of diseases of alfalfa caused by microbes, nematodes, and viruses, as well as arthropod pests of alfalfa. The glossary provides definitions of terms related to plant pathology in general and to diseases and disorders of alfalfa in particular.
