Compendium of Conifer Diseases


Book Description

Producing Christmas trees is big business. Every year, growers in the United States and Canada deliver 30 to 40 million trees to consumers, earning $2 billion in revenue. Growers in Europe produce an additional 110 million trees, earning $1.64 billion. To prepare for future crops, growers also plant up to three times as many trees as they harvest every year. Bringing each crop to market involves years of intensive management. The critical information needed to manage diseases and disorders of all types of conifer trees is provided in Compendium of Conifer Diseases, Second Edition. Written by 102 experts from 18 countries, this new edition presents the modern world of forest pathology. Forests today grow under increasing stress from an ever-growing human population, newly identified and invasive species of pathogens, and a changing climate. And since publication of the first edition of this compendium in 1997, diagnostic tools have evolved considerably, enabling more precise identification of pathogens, greater understanding of population genetics, and better understanding of evolutionary relationships among various species. All of these factors are addressed in the new compendium.




Fungal Strategies of Wood Decay in Trees


Book Description

Wood-destroying fungi play an important role in nature, because they are the only forms of life capable of reducing wood to its initial constituents. However, they can also be dangerous for people and property, as they can impair the stability and fracture-safety of trees. This book gives detailed information, based on new and original scientfic findings, on the examination and effects of the most important species of fungi associated with failure of infected urban trees. In addition, new ways are presented for predicting the advance of decay in the living tree. The subject is illustrated and made easily accessible by numerous colored photos of fungus fruit bodies, defect symptoms, and macroscopic and microscopic pictures of wood decay. A detailed introduction to the fundamentals of wood pathology provides a way into the subjects of applied mycology and tree care for readers without previous special knowledge. Francis W.M.R. Schwarze, National Diploma of Arboriculture at Merrist Wood College, UK (1991), Master of Science in Pure, Applied Plant and Fungal Taxonomy, University of Reading, UK (1992), doctorate at Freiburg University (1995), since 1996 assistant at the Institute for Forest Botany and Tree Physiology at Freiburg University, concentrating on research into wood-destroying fungi and host-fungus interactions. Julia Engels, Diploma Forester at Freiburg University (1995), doctorate on root fungi at Freiburg University (1998). Since 1998 active in tree care and mycology in Luxembourg. Claus Mattheck, born 1947, doctorate in theoretical physics (1973), qualified as lecturer on damage studies at Karlsruhe University (1985), and now teaches there as Professor. Since 1991 he has been an officially appointed and attested expert on tree mechanics and fracture behaviour. Has been awarded numerous prizes for research and publication. Head of the Biomechanics Department at the Karlsruhe Research Centre.




Westcott's Plant Disease Handbook


Book Description

Westcott’s Plant Disease Handbook, 7th Edition, should be useful to anyone with a keen interest in gardening. The seventh edition uses the traditional convenient format of previous editions providing easy access to essential information quickly with special dictionary-type entries on plant hosts and on symptoms. It provides useful cross references, indexes, illustrative plates of 34 key diseases, and 40 black and white illustrations of other diseases. New and updated material includes: significant taxonomic changes in fungi, bacteria, viruses and nematodes, and recently discovered diseases and new hosts for previously known plant-pathogens.







Westcott's Plant Disease Handbook


Book Description

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.
