Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Control of the Chestnut Bark Disease Sir: I have the honor to transmit herewith and to recommend for publication as a Farmer's Bulletin a manuscript entitled "The Control of the Chestnut Bark Disease," by Dr. Haven Metcalf, Pathologist in Charge, and Prof. J. Franklin Collins, Forest Pathologist, of the Office of Investigations in Forest Pathology. The writers describe their method of restricting the spread of this dangerous disease by destroying advance infections, a method which is already being applied on a large scale by the State of Pennsylvania. It is hoped to perfect plans whereby through general cooperation the disease may be kept within the territory where infection is already general and the largest and best chestnut forests of the country, especially those of the south Appalachians, be kept permanently free from the disease. The experimental data upon which the recommendations contained in this publication are based will be published in full in a forthcoming bulletin of the Bureau of Plant Industry.

Download or read book The Nature of Disease in Plants written by Robert P. Scheffer and published by Cambridge University Press. This book was released on 1997-01-28 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about how plants get diseases, from the origins and evolution of parasites to how the great plant epidemics developed. The basic premise of the book is that the conditions favouring disease are inherent in agriculture and that diseases become destructive because of human activities. It also deals with how people have dealt with plant diseases in history. Included in the book are the natural histories of some of the most damaging plant diseases, worldwide, with discussions of why each became destructive. Diseases are grouped according to the most significant factors in the development of epidemics: in every case this is due to a human factor. Discussion of each model disease proceeds from observable facts to more complex concepts; thus, the reader with little knowledge of plant pathology should find the book easily understandable.

This book was released on 2019-04-01 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: The American chestnut, whitebark pine, and several species of ash in the eastern United States are just a few of the North American tree species that have been functionally lost or are in jeopardy of being lost due to outbreaks of pathogens and insect pests. New pressures in this century are putting even more trees at risk. Expanded human mobility and global trade are providing pathways for the introduction of nonnative pests for which native tree species may lack resistance. At the same time, climate change is extending the geographic range of both native and nonnative pest species. Biotechnology has the potential to help mitigate threats to North American forests from insects and pathogens through the introduction of pest-resistant traits to forest trees. However, challenges remain: the genetic mechanisms that underlie trees' resistance to pests are poorly understood; the complexity of tree genomes makes incorporating genetic changes a slow and difficult task; and there is a lack of information on the effects of releasing new genotypes into the environment. Forest Health and Biotechnology examines the potential use of biotechnology for mitigating threats to forest tree health and identifies the ecological, economic, and social implications of deploying biotechnology in forests. This report also develops a research agenda to address knowledge gaps about the application of the technology.

Download or read book A Natural History of North American Trees written by Donald Culross Peattie and published by Trinity University Press. This book was released on 2013-10-10 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A volume for a lifetime" is how The New Yorker described the first of Donald Culross Peatie's two books about American trees published in the 1950s. In this one-volume edition, modern readers are introduced to one of the best nature writers of the last century. As we read Peattie's eloquent and entertaining accounts of American trees, we catch glimpses of our country's history and past daily life that no textbook could ever illuminate so vividly. Here you'll learn about everything from how a species was discovered to the part it played in our country’s history. Pioneers often stabled an animal in the hollow heart of an old sycamore, and the whole family might live there until they could build a log cabin. The tuliptree, the tallest native hardwood, is easier to work than most softwood trees; Daniel Boone carved a sixty-foot canoe from one tree to carry his family from Kentucky into Spanish territory. In the days before the Revolution, the British and the colonists waged an undeclared war over New England's white pines, which made the best tall masts for fighting ships. It's fascinating to learn about the commercial uses of various woods -- for paper, fine furniture, fence posts, matchsticks, house framing, airplane wings, and dozens of other preplastic uses. But we cannot read this book without the occasional lump in our throats. The American elm was still alive when Peattie wrote, but as we read his account today we can see what caused its demise. Audubon's portrait of a pair of loving passenger pigeons in an American beech is considered by many to be his greatest painting. It certainly touched the poet in Donald Culross Peattie as he depicted the extinction of the passenger pigeon when the beech forest was destroyed. A Natural History of North American Trees gives us a picture of life in America from its earliest days to the middle of the last century. The information is always interesting, though often heartbreaking. While Peattie looks for the better side of man's nature, he reports sorrowfully on the greed and waste that have doomed so much of America's virgin forest.
