Section one 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 those caused by nematodes. The parasitic flowering plant dodder is also discussed. Section two covers arthropod (insect) pests, detailing their life cycles, damage, 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 and seed pests are given special sections, as is a livestock pest, the blister beetle. Section three, titled ‘Noninfectious Diseases and Abiotic Conditions,’ discusses the effects and management of genetic variations and abnormalities, herbicide injury, high-temperature flooding injury, nutrient deficiencies and toxicities, foliar freeze injury, and winter injury. The appendix presents an updated list of common names of diseases of alfalfa caused by microbes, nematodes, and viruses, as well as arthropod insect pests of alfalfa.
Celebrating the 100th Anniversary of virology, Tobacco Mosaic Virus: One Hundred Years of Contributions to Virology is an anthology of this past century`s classic papers written about tobacco mosaic virus and its impact in the field of virology and related studies. A historical perspective shows an appreciation for this important virus and how these classic experiments have led to our current understanding of all types of viruses today.
Exercises in Plant Disease Epidemiology, Second Edition provides basic topical background information of each exercise together with suggestions for further reading. This information, along with classroom instruction, will make possible the practical implementation of the exercises and help build confidence and benefit the individuals concerned. All exercises are supported by software that is either public domain or commonly available commercially, allowing greater accessibility for students and users overall. For further aid to accessibility, the book’s Appendix includes information on all the commonly used software.
This book is significant because it is the definitive resource on viruses that infect the plant species that make up the most important food crops in the world – Poaceae (Gramineae) – which include barley, maize, rice, rye, sorghum, sugarcane, triticale, wheat, forage, ornamental, and lawn. This grass family is among the largest of all plant families consisting of approximately 700 genera and 10,000 species. Nearly twenty percent of plant viruses are known to infect graminaceous hosts resulting in significant agricultural economic losses. The Poaceae are one of the most important plant families in terms of the number of species, worldwide distribution, ecosystems and as ingredients of human and animal food. It is not surprising that they support many parasites including more than 100 severely pathogenic virus species, of which new ones are being regularly described. This book results from the contributions of 150 well-known specialists and presents for the first time an in-depth look at all the viruses (including the retrotransposons) infesting one plant family.
The Compendium of Turfgrass Diseases, Third Edition is devoted entirely to the diagnosis and control of approximately 80 diseases affecting grasses maintained for fine turfs on residential and commercial lawns, sod farms, golf courses, sports fields, bowling greens, cemeteries, and other areas. Since it was first published in 1983, more than 45,000 copies of the Compendium of Turfgrass Diseases have been distributed all across the world. With information provided and reviewed by more than 40 plant pathologists and turf specialists, this book will help you identify problems quickly and accurately before they become unmanageable and costly to control. When a disease symptom occurs, infected areas of the turfgrass can be matched to one of the illustrations in the book and the accompanying text will provide more about the symptoms, causes, cycles and control of the disease identified
This volume consists of 85 chapters that highlight recent advances in our knowledge of the viruses that infect plants and fungi. It begins with general topics in plant virology including movement of viruses in plants, the transmission of plant viruses by vectors, and the development of virus-resistant transgenic plants. The second section presents an overview of the properties of a selection of 20 well-studied plant viruses, 23 plant virus genera and a few larger groups of plant viruses. The third section, which is abundantly illustrated, highlights the most economically important virus diseases of cereals, legumes, vegetable crops, fruit trees and ornamentals. The last section describes the major groups of viruses that infect fungi.
Covering the key techniques used when working with fungal plant pathogens, this practical manual deals with recognition of disease symptoms, detection and identification of fungi and methods to characterise them well as curation, quarantine and quality assurance.The book is unique in its practical focus, providing an overview of both traditional and emerging methods and their applications, and detailed protocols on completion techniques such as microscopy, PCR, ELISA, freeze drying and DNA storage. Fungal Plant Pathogens provides a valuable guide to investigating fungal plant diseases and interpreting laboratory findings.
Part I outlines the infectious diseases that affect tomato—including those caused by fungi and oomycetes, bacteria, phytoplasmas, viruses, and viroids—along with postharvest diseases and disorders and diseases caused by nematodes. Part II covers arthropod pests: namely, mites, insects, and “worm” pests. Part III examines noninfectious diseases, disorders, and damage: namely, physiological diseases, nutritional disorders, herbicide damage, and genetic diseases. Part IV, which discusses diseases of undetermined etiology, has been reorganized to adopt the format used elsewhere in the book.
This colorful guidebook is essential for ensuring early detection of disease and insect symptoms in order to implement control measures to maximum yields and product quality. It is an invaluable resource for anyone involved in healthy apple and pear production, including plant pathologists, entomologists, pomologists, extension agents, master gardeners, horticulturists, IPM practitioners, pesticide applicators, agrochemical professionals, private consultants, and growers.
The Garden and Greenhouse Flowers manual is a reference manual on diseases which attack garden and greenhouse flowers. The manual identifies various types of diseases which are known to invade these plants located throughout North, Central, and South America. The recordings include diseases caused by fungi, bacteria, viruses, viroids, phytoplasmas, and nematodes. Causal disease agents are described and illustrated in some cases and diseases and disease control measures are also discussed. Content: Preface, Illustrations, Disease Control and Management, Host Plants and Their Diseases, Headings Under Which Diseases Are Described, List of Land-Grant Institutions and Agricultural Experiment Stations in the United States, Glossary.
