Book Description
Excerpt from The Diseases and Pests of the Rubber Tree In 1911 the diseases which were known to attack the rubber tree were described in The Physiology and Diseases of Hevea brasiliensis. The number of recorded diseases was then comparatively small, and it was possible to include with them a general account of the structure and physiology of the tree, and a summary of those tapping experiments which promised to afford a foundation for a theory of rubber tapping. That book has now been out of print for some time, and several inquirers have suggested the issue of a second edition. But the number of known diseases of Hevea has, unfortunately, been considerably extended during the last eight years, while the work of numerous investigators in this field has added largely to our knowledge of both old and new ones. Consequently, rubber diseases now demand a volume to themselves; and it has therefore been decided to divide the subject-matter of the former book, and to publish a separate account, revised and brought up to date, of the diseases and pests only. It is hoped that it will be possible, at some future date, to deal similarly with the other half of the original volume. As the book is intended primarily for the rubber planter, technical botanical details have been avoided as much as possible. It is not practicable to exclude them altogether, nor, indeed, is that necessary, for rubber cultivation has made the planter familiar with technical botanical terms to a degree hitherto unknown in tropical agriculture.

Book Description
Forest Microbiology: Tree Diseases and Pests, Volume Three in the Forest Microbiology series, provides an overview of major disease agents of trees, including viruses, phytoplasma, bacteria, fungi, nematodes and major insect pests. With a strong emphasis on genetics, biochemistry, physiology, evolutionary biology and population dynamics of the organisms involved, this book provides a comprehensive understanding on the health of forests. Sections cover important pest threats such as bark beetles, emerald ash borer, coffee borers, leaf cutting ants, cocoa mirids, and more. This volume highlights a range of emerging diseases of forest trees in temperate and tropic regions as well as information on habitats. Forest trees play crucial roles not only for mitigating effects of the climate change but also for their considerable economic and ecological value. Forest trees are equally vital as an alternative bioenergy source and play important roles in pollution abatement and the maintenance of biodiversity. Timber and its associated products from forest trees contribute substantially to the revenue generation of many countries of the world. Includes case studies of complex diseases of economically important trees Highlights novel approaches to managing tree pests and diseases in a changing climate Focuses on the many functions of microbial disease agents of trees Addresses major insect pests of boreal, temperate and tropical trees
