Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Blue Mold of Tobacco Downy mildew first made its appearance in the United States in four widely separated seed beds of cigar wrapper tobacco in Gadsden County, Florida in the latter part of March 1921. By the beginning of April it had been reported from a number of seedbeds in the adjoining Georgia County of Decatur. Before the end of the growing season the disease had spread over all of the cigar wrapper area in the Florida Georgia district. With the aid of pathologists from the United States Department of Agriculture (81, 82, 83) the disease was eradicated by burning diseased plants and by drenching seedbeds with formaldehyde solution. A weak Bordeaux mixture, 2-2-50, was recommended as a spray for healthy leaves. After this initial outbreak blue mold did not appear again until 10 years later, when it broke out with even greater vehe mence than before, originating in the same florida-georgia area where it had first appeared in 1921. Before we discuss the spread of the disease from 1931 to the present it is advisable to spend a little time in consideration of how the disease happened to appear on cultivated tobacco in the United States, including the possibilities either that it was introduced into the country or that it is endemic. A great deal of conjecture has arisen since 1921 in an attempt to explain the presence of this disease in North America. Regardless of the fact that all theories are still conjecture and probably must necessarily remain so, the evidence for both endemism and introduction from an extra-territorial source will be given for the record.

Its origin was traced in some instances to cull piles, diseased seed, and infection from tomato plantings.

Download or read book Plant Pathology written by George Agrios and published by Elsevier. This book was released on 2012-12-02 with total page 646 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant Pathology presents information and advances in plant pathology including disease induction and development and disease resistance and control. This book is organized into two major parts encompassing 14 chapters that focus on diseases, pathogenicity, and pathogen variability. The first part of the book deals with general considerations of disease, the disease cycle, parasitism and pathogenicity, and the variability in pathogens. This is followed by a presentation of the mechanisms by which pathogens cause disease and plants resist disease. Core chapters focus on the effects of pathogen-produced enzymes, toxins, growth regulators, and polysaccharides on the structural organization and on the basic physiological processes of photosynthesis, translocation, and respiration. The chapters also discuss the defense mechanisms of the plant. Moreover, this book explains the genetics of host-parasite interaction, effects of environment on disease development, and control. The second part of the book deals with the infectious diseases caused by fungi, bacteria, parasitic higher plants, viruses, and nematodes. This part also looks into the noninfectious diseases caused by environmental factors. The diseases caused by each type of pathogen are discussed comprehensively as a group and are subsequently discussed individually in detail. This book includes diagrams of cycles for each disease to create visual images for better understanding of the disease and message retention. This book is ideal for students with introductory course in plant pathology.

This book was released on 1995-08-24 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bridging the fields of conservation, art history, and museum curating, this volume contains the principal papers from an international symposium titled "Historical Painting Techniques, Materials, and Studio Practice" at the University of Leiden in Amsterdam, Netherlands, from June 26 to 29, 1995. The symposium—designed for art historians, conservators, conservation scientists, and museum curators worldwide—was organized by the Department of Art History at the University of Leiden and the Art History Department of the Central Research Laboratory for Objects of Art and Science in Amsterdam. Twenty-five contributors representing museums and conservation institutions throughout the world provide recent research on historical painting techniques, including wall painting and polychrome sculpture. Topics cover the latest art historical research and scientific analyses of original techniques and materials, as well as historical sources, such as medieval treatises and descriptions of painting techniques in historical literature. Chapters include the painting methods of Rembrandt and Vermeer, Dutch 17th-century landscape painting, wall paintings in English churches, Chinese paintings on paper and canvas, and Tibetan thangkas. Color plates and black-and-white photographs illustrate works from the Middle Ages to the 20th century.

Download or read book Medicinal Aromatic and Stimulant Plants written by Johannes Novak and published by Springer. This book was released on 2020-10-10 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The agricultural sector of medicinal (including plant stimulants) and aromatic plants is characterized by an enormous number and diversity of species. Only a few of them can be considered cultivated crops in which significant breeding efforts are made. For most species, however, breeding is performed in short-term projects only. Therefore, basic knowledge about these species is still fragmentary. Our intention is to compile and organize the available information on the most commonly utilized plant species into one publication, thereby providing a standardized resource for the researchers and the grower community. This book therefore provides reference source materials for a wide variety of plant species used for human consumption due to their flavor, medicinal or recreational properties. It is divided into a section of general topics on genetic resources, breeding adaptation of analytic methods and a compilation of basic data for DNA content, chromosome number and mating system followed by a section of 20 monographs on a species or species groups.
Download or read book The Downy Mildews Genetics Molecular Biology and Control written by Aleš Lebeda and published by Springer Science & Business Media. This book was released on 2009-01-23 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Knowledge of downy mildew pathogens and diseases has increased significantly in taxonomy, phylogeny, genetics, molecular biology, host-parasite interactions, ecology, epidemiology and control. The opportunity to update comprehensively the major advances in these areas was created by the 2nd International Symposium on Downy Mildews held in July 2007 at Olomouc (Czech Republic). Keynote contributions from this meeting are published here in 14 chapters that provide the most authoritative and recent analysis of these biotrophic plant pathogens and their interactions with plants. It will be an invaluable resource to students and researchers in plant pathology, mycology, taxonomy, plant biology and crop protection.
