Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Text-Book of the Diseases of Trees Some fifty years ago a number of able investigators, of whom only Saxesen, Th. Hartig, and Ratzeburg need be named here, applied themselves to the study of insects. The life-history of forest insects, their harmfulness or usefulness, soon became the favourite study of many practical foresters, and in a few decades the joint efforts of numerous workers were rewarded by the elevation of Forest Entomology to the position of a much appreciated subject of scientific instruction, which has become the common property of all educated foresters. The case was otherwise with those plant-diseases which cannot be ascribed to the injuries of animals. Their investi gation was delayed until quite recently; for it was only after botanical science, by the aid of its chief instrument, the microscope, had obtained a clear insight into the normal strue ture and vital phenomena of plants, and especially after the study of fungi had been prosecuted in the last few decades by a series of distinguished investigators, that the examination of the phenomena of disease in the life of plants could be undertaken with a prospect of success.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Manual of Tree Diseases The steadily accumulating knowledge of the diseases of trees in the United States has never been brought together and made available to the general public. The intention of this Manual is to describe and suggest means of control for the tree diseases that have been most studied. Much remains to be learned about many of these diseases, and still many more have never been investigated. Therefore, in the treatment of this subject there are many unavoidable limitations which the trained reader will perceive. The diseases of fruit-trees, and of field and vegetable crops, have received the attention of plant pathologists in most parts of the country for many years. The results of these investigations have been made available to the growers of these crops in various ways. On the other hand, the diseases of forest, shade, and ornamental trees have been largely neglected until very recently. Tree diseases cause enormous losses in the large tracts of forests on which we depend for timber. The timber owner has been slow to adopt the fundamentals of scientific forest practice, and so far methods for the control of forest-tree diseases have not begun to operate in reducing losses. The owners of shade and ornamental trees are constantly confronted with diseases which they wish to control. They have become accustomed to controlling insects, but the fundamentals involved in the appearance of a disease and the measures necessary to protect trees from further damage are largely puzzling to them. An understanding of the cause of disease is essential to the undertaking of adequate control measures. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book excerpt: Excerpt from Diseases of Deciduous Forest Trees A series of investigations has been conducted for several years by the senior writer in another region where an extensive mixed forest has been severely injured by sulphur gases emanating from large copper smelters. The forest consists largely of oaks and pines grow ing on an extremely poor and sterile soil, and the general develop ment of the forest, even before the action of the sulphur gases, was very poor. The different species of forest trees showed a marked difference in susceptibility. The order, of susceptibility, beginning with the trees most easily killed, is as follows.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Text-Book of the Diseases of Trees The foundation of a science of Mycology by Berkeley, de Bary, and Tulasne, pursued by Brefeld, Zopf, and others, has led to a knowledge of the biology of fungi highly creditable to the industrious observers who have explored this domain of the vegetable kingdom; while the gradual building up of the science of plant-physiology from the days of Knight and Hales, De Saussure and Boussingault, to those of Sachs and Pfeffer, has placed us in possession of a vast amount of information as regards normal life processes in plants. Until much more recently, however, it cannot be said that we have had a science of the pathology of plants - i.e. the study of abnormal physiology - of anything like the same importance, in spite of the splendid and progressive attempts of Berkeley, Frank, and Sorauer to found one. In the particular department he has cultivated, Robert Hartig has succeeded in founding a plant-pathology really worthy of the name, and I would especially emphasize this, that his researches are so thoroughly elucidative of pathological phenomena, in that he studies not only the nature of the structural lesions and of the physiological disturbances consequent on these, but also the factors of the environment which throw light on the question.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Stress Triggered Tree Diseases: The Diebacks and Declines In recent decades, dieback and decline diseases have killed or damaged millions of trees in the northeastern United States. Most hardwood tree species probably have been affected by dieback and decline diseases at some point, but relatively few species have suffered greatly. Unfortunately, the species affected most severely are among the most important ones. And the incidence and severity of these diseases seems on the rise. In this publication, special emphasis is placed on the decline and mortality of oak initiated by gypsy moth defoliation. The significant impact of this widespread defoliation in recent years has prompted great concern and considerable research.
