Worldwide soybean crop yields can achieve USD$130 billion per year in farm-level sales, but around 13% of these yields are lost to disease. Effective disease management could generate significant economic benefits, and while disease management strategies do exist, their application remains limited among producers, often due to an incomplete understanding of disease incidence and severity, as well as perceived complexities of these strategies and a lack of information regarding success rates. This book presents an economic perspective on disease control, with an emphasis on producer choice among alternative technologies and potential changes in cropping systems. It provides an overview of global soybean diseases, their economic significance and management, and covers farm-level decision making, economic payoffs of alternative disease practices and key uncertainties. The book also outlines a global economic model that evaluates disease distribution and management implications.
The 1970s were the heyday of research on bedding plants—a time when both interest and innovation blossomed. But since then, a lot has changed! Many new species and cultivars have been introduced, changes in propagation procedures have resulted in more frequent outbreaks of diseases and infestations of insect pests, and the long-distance exchange of plant materials has facilitated worldwide movement of new and sometimes pesticide-resistant pathogens and arthropod pests. Management strategies have changed significantly, as well, and now include enhanced clean stock production for some crops, more rigorous sanitation practices, and applications of improved chemical pesticides and biological controls. Compendium of Bedding Plant Diseases and Pests summarizes all the latest research-based information about diseases, disorders, and arthropod pests of annuals grown as bedding plants. The information has been compiled by A. R. Chase, Margery L. Daughtrey, and Raymond A. Cloyd.
Cucumber mosaic virus (CMV) has the broadest host range of any virus, and among the 1,000-plus host plants it affects are economically important food crops such as tomato, pepper, and lettuce. New species of host plants are being identified every year, mostly among weeds and ornamental plants as the latter become more popular. This is especially true in the developing world, where many plant species have not yet been surveyed. To date, most publications on CMV have focused on specific aspects of the virus. That has changed with release of this new book by APS PRESS, Cucumber Mosaic Virus. Written by an international group of 29 experts on various aspects of CMV, this comprehensive book provides key findings from 100 years of research in a single volume. Cucumber Mosaic Virus reprints the first three papers on cucumber mosaic disease published in 1916 and covers the literature since then on various aspects of CMV: the pathology associated with CMV, the molecular biology of CMV, the purification of CMV, the use of CMV as a protein expression vector or a gene-silencing vector, and the structure, biology, and evolution of CMV satellite RNAs.
Research goes back more than 100 years for some genera of plant-pathogenic bacteria, and a lot is known about the diseases they cause, including how to manage them. The opposite is true of the genus Acidovorax. Acidovorax pathogens and diseases have only recently been considered as economically important threats to food crops worldwide—among them, cereals such as corn, wheat, oats, barley, and rice. Thus, little is known about Acidovorax pathogens, and options for managing the diseases they cause are limited. Plant-Pathogenic Acidovorax Species is the first comprehensive effort to collate information on these pathogens. This book provides an up-to-date overview of plant diseases caused by Acidovorax species, addressing taxonomy, epidemiology, diagnosis, and management. In addition, the book considers nonpathogenic plant-associated or free-living species of Acidovorax.
Este libro consta de 32 capítulos resultado de la participación de los mejores grupos de investigación de España relacionados con el control biológico de enfermedades de cultivos agrícolas y forestales. Los capítulos están agrupados en dos secciones, una donde se abordan aspectos generales del control biológico de enfermedades vegetales y su futuro; y una segunda donde se muestra su aplicación en distintos patosistemas presentes en la agricultura. Se trata de un libro que combina aspectos básicos con otros muy aplicados, y con el que se pretende proporcionar las claves para entender el funcionamiento y la puesta en práctica del control biológico de enfermedades vegetales a un amplio público preocupado por la falta de alternativas no químicas a los producto fitosanitarios en los cultivos, desde el consumidor hasta el investigador, pasando por los docentes, asesores, técnicos y agricultores.
The second edition of the highly popular “Westerdijk Laboratory Manual Series No. 1: Fungal Biodiversity” is now available. The volume (hard copy, full colour) is extended with 150 pages. This Laboratory Manual focuses on techniques for isolation, cultivation, molecular and morphological study of filamentous fungi and yeasts. It has been developed as a general text over many years, which is based on the annual mycology course given at the Westerdijk Fungal Biodiversity Institute in Utrecht, The Netherlands. The manual provides an introductory text to systematic mycology, starting with a concise treatise of Hyphochytridiomycotaand Oomycota, which have long been subject of study by mycologists, but are now classified in the Kingdom Chromista. These are followed by sections on the groups of “true fungi”: Chytridiomycota, Blastocladiomycota, “Zygomycota”, Ascomycota and Basidiomycota.
El interés científico, fitopatológico, técnico y mediático suscitado en España por la bacteria Xylella fastidiosa no es comparable al despertado por ningún otro tema relacionado con la sanidad vegetal en las últimas décadas. A pesar de la cantidad de información disponible sobre este patógeno, no toda tiene el rigor necesario y por ello este libro pretende ofrecer información fiable, proporcionada por los expertos españoles en el tema y por investigadores de otros países con amplia experiencia en esta bacteria. El libro incluye 15 capítulos que pretenden ofrecer una revisión actualizada, pero también realista, práctica y crítica del estado actual de los conocimientos sobre esta bacteria y las enfermedades (bacteriosis) de las que es responsable. Consta de nueve capítulos generales y de seis más específicos sobre la situación y la problemática de las enfermedades producidas por X. fastidiosa en América y en Europa, incluyendo España. La lectura de los distintos capítulos nos lleva a profundizar en el complejo sistema que constituyen X. fastidiosa, sus plantas huéspedes, sus vectores y las condiciones medioambientales del entorno.
Rice is among the most significant food crops on the planet, covering an area of more than 154 million hectares, according to the International Rice Research Institute. And while consumption of rice increases each year, the spread and increased incidence of various rice diseases, disorders, and pests pose greater risks to production. Better, more up-to-date management practices are needed to keep feeding the world. The Compendium of Rice Diseases and Pests, Second Edition, was developed to help agricultural professionals and academics get the latest information on the management of diseases, insect pests, and abiotic disorders of this important crop. Published more than 25 years after the first edition, this new full-color update presents the major shifts in rice cultivation, including the more extensive use of hybrid rice, herbicide resistance, new biotechnologies and fungicides, the continued shrinkage of genetic diversity, and more intense cultural management systems. To help foster worldwide communication and information exchange on rice and its many production challenges, a group of top rice experts from various areas of the world were tapped as editors, along with a team of contributing authors specializing in key areas of rice health. Together they updated much of the information in the first edition, as well as added important newly discovered diseases and pests, ultimately providing better and fresher insights into the diseases, disorders, and pests that affect the world’s most predominant human food crop.
Plant bacterial diseases are a major factor in economic crop losses worldwide. The transportation and use of clean, pathogen-free seed and propagative material is the most vital step in controlling bacterial diseases, but this requires accurate, rapid, sensitive, and reliable pathogen detection. The all-new second edition of Detection of Plant-Pathogenic Bacteria in Seed and Other Planting Material is an essential, easy-to-use lab manual describing and illustrating the latest methods for detecting a wide range of bacteria responsible for many of the world’s most economically significant bacterial plant diseases in crops. Yet this book does more than describe and illustrate the use of real-time PCR, rapid PCR-based assays, and other methods for specific, sensitive detection of bacteria in seed and propagative material. Its 48 chapters offer background information on the given bacteria and the diseases they cause, describe symptoms, detail their epidemiology, identify strategies for disease management, and provide protocols for detection in thorough detail.
