Book excerpt: Excerpt from Diseases of Cultivated Plants and Trees There are many causes which favour the spread and increase of disease at the present day, which had no existence in bygone times, perhaps the most potent is that commonly known as 'rapid transit.' Undoubtedly a change of seed is good, but, as experience has proved, you never know what disease you are intro ducing, and in many instances it is impossible to detect anything wrong until too late. The facility with which seeds, tubers, and even living plants can now be sent to the uttermost parts of the earth is a source of great danger from the point of view of introducing new diseases, and unless something in the way of a quarantine is insisted upon in every country, it appears highly probable that in course of time those diseases, which assume the proportions of an epidemic, Will be equally abundant wherever the host-plant is cultivated. Where total prohibition is not considered necessary, quarantine, which has answered so well in the case of animal diseases, might with advantage be applied in the case of fruit-trees, etc. The trees should be planted in some suitable place, and be examined from time to time by some qualified person. After a season's growth they might be allowed to pass into the country, if free from disease. I am quite aware that some people will say this idea is not practicable, and further, such precautions are -not necessary. There is certainly nothing impracticable; it is quite as easy to plant a tree in one place as another. The cost of a tree that has been in quarantine for a season would certainly cost more than it would at the moment of landing, but on the one hand the purchaser would secure a tree free from disease, whereas on the other hand the tree might prove to be infected With some disease. The fact that the most destructive diseases attacking fruit-trees and other plants in Europe, also eventually appear in whatever part of the world such trees are cultivated, is absolute proof that the disease has been conveyed along with the plant.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Diseases of Cultivated Plants and Trees So widely spread and, it may be added, often so intelligent is the interest now taken in the incidence and the dissemination of the diseases which affect cultivated plants, and at the same time so important is a proper conception of the causations and the treatment of these diseases, that a work which deals with them cannot fail to be welcomed. Much has been and much is daily being done to advance our knowledge of plant-diseases and to increase our ability to cope with the practical difficulties that their presence creates. But the literature of the subject is so widely scattered, and the results of individual investigations so often tend, when settling some immediate difficulty, to create new difficulties, to open up new lines of research, and to indicate new principles of treatment, that in the absence of a compact, general review of the actual state of affairs, the practical man is apt to feel at a loss as to how matters really stand, and at times is disposed to doubt the soundness of the advice he is urged to follow. The conditions necessary for the preparation of such a work as is called for are in the first place an intimate knowledge of the labours of a host of investigators widely scattered throughout the world, with at the same time ready access to the literature in which these results are embodied.

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.

Download or read book Bacterial Diseases of Crop Plants written by Suresh G Borkar and published by CRC Press. This book was released on 2021-06-30 with total page 616 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food and agriculture is an important component in the development and survival of civilizations. Around half of the world's population and their economies are influenced by agricultural farm production. Plant diseases take as much as a 30 percent toll of the crop harvest if not managed properly and efficiently. Bacterial diseases of crop plants are important in plant disease scenarios worldwide and are observed on all kinds of cultivated and commercial value plants including cereals, pulses, oilseeds, fruits, vegetables, cash crops, plantation crops, spices, ornamentals and flowering plant, forage crop, forest trees, and lawn grasses. Bacterial diseases are widespread and are difficult to identify and to control. Few pesticides are available for use in control, and many plant pathologists are not well trained in the management of bacterial diseases. Bacterial Diseases of Crop Plants offers concise information on bacterial diseases of crops, proving a valuable asset to students, scientists in industry and academia, farmers, extension workers, and those who deal with crops that are vulnerable to bacterial diseases. The book contains 13 chapters featuring bacterial diseases of individual crops and is illustrated with full color photographs throughout providing amazing characterization of the diseases. It also includes information on bacterial diseases that appear on different crops across the continents, thereby making the content of interest to plant pathologists around the world. Bacterial diseases are of great economic concern, and their importance in overall losses caused by various other pathogens, such as fungi and viruses, is often undermined in developing countries.

Book excerpt: Principles of Plant Disease Management is intended to provide a substantive treatment of plant disease management for graduate and undergraduate students in which theoretical and practical elements are combined. Reference is made to specific diseases and control practices to illustrate basic principles or strategies. The section on epidemiology includes a chapter in which arthropod vectors (aphids, leafhoppers, whiteflies, Coleoptera and mites) are briefly discussed, and the section on control includes references to the use of crop varieties with resistance to such vectors, and also contains information on mechanical, cultural, biological and chemical measures that contribute to vector control. The technology of disease management is presented according to epidemiological principles Sections on diagnosis, epidemiology, environmental factors, disease forecasting, disease control (exclusion, physical, chemical and biological), plant resistance, cultural modifications to suppress epidemics, effects of chemicals and their major groups and uses, and examples of disease management in practice are included A bibliography and index are appended
