Diseases of trees and shrubs

Author: Wayne A. Sinclair
Publisher: Cornell Univ Pr
ISBN: UOM:39015018973886
Release Date: 1987-07
Genre: Gardening

Diseases of Trees and Shrubs is a comprehensive pictorial survey of the diseases of, as well as the environmental damage to, forest and shade trees and woody ornamental plants in the United States and Canada. An authoritative reference, it is also a reliable and handy diagnostic tool that will simplify the identification of specific plant diseases by focusing on signs and symptoms that can be seen with the unaided eye or with a hand lens. This long-needed book gives readers complete, up-to-date information in an easily understood and convenient way. Each of the 247 color plates faces a page of explanatory text covering the biology and ecology (including host and geographic ranges) of the disease-causing agents (pathogens), a list of key references (there are more than 2,250), and, in some cases, black-and-white illustrations of pathogens. Selected information about biological and cultural control is provided. Scientific terms other than Latin names of pathogens are used only when necessary, and a glossary of terms and a comprehensive index are included. The color plates contain more than 1,700 illustrations of the diseases and injuries that some 350 biological agents and environmental factors cause to more than 250 species of plants. The book also serves as a guide to hundreds of other diseases related to those shown. The authors have used three levels of organization for this book. At the first level, diseases caused by biological agents are separated from those caused by environmental stimuli. At the second level, most diseases are grouped according to the plant part affected: leaves, twigs, limbs, roots, trunks, or the entire plant. At the third level, diseases are presented according to the taxonomic relationships among the pathogens. For this major project, the authors examined and photographed diseases and environmental damage in the field, visiting more than 50 states and Canadian provinces. Their book reflects the most important developments in fungal biology and taxonomy, plant bacteriology, virology, and environmentally induced stress in plants. It summarizes information about newly discovered diseases and provides up-to-date accounts of olds ones. Diseases of Trees and Shrubs can be profitable reading for anyone whose technical training does not extend beyond general biology, yet will also be informative to advanced students and plant pathologists. It will be welcomed by agricultural and horticultural advisers, plant inspectors, arborists, nursery professionals, landscapers, foresters, and urban planners. Wayne A. Sinclair is a Professor of Plant Pathology, Howard H. Lyon is Biological Photographer (retired), Department of Plant Pathology, and Warren T. Johnson is Professor of Entomology, all at Cornell University.

Forest Health: An Integrated Perspective is the first book to define an ecologically rational, conceptual framework that unifies and integrates the many sub-disciplines that comprise the science of forest health and protection. This new global approach applies to boreal, temperate, tropical, natural, managed, even-aged, uneven-aged and urban forests, as well as plantations. Readers of the text can use real datasets to assess the sustainability of four forests around the world. Datasets for the case studies are at www.cambridge.org/9780521766692, and the text provides stepwise instructions for performing the calculations in Microsoft Excel. Readers can follow along as the editors perform the same calculations and interpret the results. Elevating forest health from a fuzzy concept to an ecologically sound paradigm, this is essential reading for undergraduate and graduate students and professionals interested in forest health, protection, entomology, pathology and ecology.

Handbook of Nature Study

Author: Anna Botsford Comstock
Publisher: Ravenio Books
ISBN:
Release Date: 2016-05-31
Genre: Science

NATURE-STUDY is, despite all discussions and perversions, a study of nature; it consists of simple, truthful observations that may, like beads on a string, finally be threaded upon the understanding and thus held together as a logical and harmonious whole. Therefore, the object of the nature-study teacher should be to cultivate in the children powers of accurate observation and to build up within them, understanding. FIRST, but not most important, nature-study gives the child practical and helpful knowledge. It makes him familiar with nature’s ways and forces, so that he is not so helpless in the presence of natural misfortune and disasters. Nature-study cultivates the child’s imagination since there are so many wonderful and true stories that he may read with his own eyes, which affect his imagination as much as does fairy lore; at the same time nature-study cultivates in him a perception and a regard for what is true, and the power to express it. All things seem possible in nature; yet this seeming is always guarded by the eager quest of what is true. Perhaps, half the falsehood in the world is due to lack of power to detect the truth and to express it. Nature-study aids both in discernment and expression of things as they are. Nature-study cultivates in the child a love of the beautiful; it brings to him early a perception of color, form and music. He sees whatever there is in his environment, whether it be the thunder-head piled up in the western sky, or the golden flash of the oriole in the elm; whether it be the purple of the shadows on the snow, or the azure glint on the wing of the little butterfly. Also, what there is of sound, he hears; he reads the music score of the bird orchestra, separating each part and knowing which bird sings it. And the patter of the rain, the gurgle of the brook, the sighing of the wind in the pine, he notes and loves and becomes enriched thereby. But, more than all, nature-study gives the child a sense of companionship with life out of doors and an abiding love of nature. Let this latter be the teacher’s criterion for judging his or her work. If nature-study as taught does not make the child love nature and the out-of-doors, then it should cease. Let us not inflict permanent injury on the child by turning him away from nature instead of toward it. However, if the love of nature is in the teacher’s heart, there is no danger; such a teacher, no matter by what method, takes the child gently by the hand and walks with him in paths that lead to the seeing and comprehending of what he may find beneath his feet or above his head. And these paths whether they lead among the lowliest plants, or whether to the stars, finally converge and bring the wanderer to that serene peace and hopeful faith that is the sure inheritance of all those who realize fully that they are working units of this wonderful universe.

Westcott s Plant Disease Handbook

Author: R. Kenneth Horst
Publisher: Springer Science & Business Media
ISBN: 9781468476828
Release Date: 2012-12-06
Genre: Science

It was a compliment to me to be asked to prepare the fourth edition of Westcott's Plant Disease Handbook, and the decision to accept the responsi bility for the fourth edition and now the fifth edition was not taken lightly. The task has been a formidable one. I have always had a great respect professionally for Dr. Cynthia Westcott. That respect has grown considerably with the completion of the two editions. I now fully realize the tremendous amount of effort expended by Dr. Westcott in developing the Handbook. A book such as this is never finished, since one is never sure that everything has been included that should be. I would quote and endorse the words of Dr. Westcott in her preface to the first edition: "It is easy enough to start a book on plant disease. It is impossible to finish it. " This revision of the Handbook retains the same general format contained in the previous editions. The chemicals and pesticides regulations have been updated; a few taxonomic changes have been made in the bacteria, fungi, and mistletoes; the changing picture in diseases caused by viruses and/or viruslike agents has been described. A few new host plants have been added, and many recently reported diseases as well as previously known diseases listed now on new hosts have been included. In addition, photographs have been replaced where possible, and the color photograph section has been retained.

Armored Scale Insect Pests of Trees and Shrubs Hemiptera Diaspididae

Author: Douglass R. Miller
Publisher: Cornell University Press
ISBN: 0801442796
Release Date: 2005
Genre: Nature

Armored scale insects are among the most damaging and least understood of the pests that prey on forest trees, fruit and nut crops, landscape ornamentals, and greenhouse plants. The passage of U.S. plant quarantine laws was prompted by devastation caused by an armored scale in the nineteenth century, and the appearance of new invasive species remains a vital concern at ports of entry and for arborists, farmers, nursery workers, foresters, and gardeners everywhere. This book provides the most comprehensive available information on the identification, field appearance, life history, and economic importance of the 110 economically important armored scale insects that are found in the United States. The authors have devised the first field key to economic armored scales, which will be invaluable to those trying to identify the pests and prevent the introduction of new exotics. (Most of the species covered are not native to the United States but broadly distributed across the globe.) The extensive color plates and highly detailed line drawings surpass anything available in other volumes on armored scale insects, and have not previously been published. Especially noteworthy are the data on distribution, host plants, and the kinds of damage caused by armored scales. The species descriptions include scientific names, synonyms, common names, field characteristics, microscopic characters, affinities, host plants, distribution by state, life history, economic damage, and selected references.
