The book is intended to provide comprehensive introduction to the important aspects of the field of forest pathology and tree diseases. The book is arranged in two major parts. The fundamental chapters, present forest diseases, pathogens, epidemics, and management that is applicable to all forest trees. The applied chapters on the individual crops that are grouped alphabetically present information on the symptoms, pathogen and integrated management of major diseases of forest trees. It was designed to give a broad overview of the field of forest pathology but with sufficient detail that they will be able to assess their specific role as practicing forestry professionals. Note: T& F does not sell or distribute the Hardback in India, Pakistan, Nepal, Bhutan, Bangladesh and Sri Lanka.
Over the last fifty years, there has been an increasing recognition that eucalypts are vulnerable to a wide range of diseases. They have suffered destructive epidemics, particularly of dieback caused by the cinnamon fungus in native forests, of foliar diseases and cankers in plantations, and of dieback of remnant trees on agricultural and grazing land. This has stimulated intensive research into the causes and management of diseases of the eucalypts. This work represents a comprehensive review of our current knowledge of the health and diseases of eucalypts.
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
Plant diseases in ornamental, aromatic and medicinal crops are common in occurrence, and account for up to 12-20% yield losses. Diseases of Ornamental, Aromatic and Medicinal Plants is a unique reference aimed to fulfil knowledge gaps on this subject. Nine chapters cover major diseases and nematode problems in important ornamental plants (cut flowers, potted flowers, flowering geophytes, and turfs), medicinal plants (tuberous and non-tuberous) and aromatic plants. The book explains the etiology, symptoms, disease cycle, economic importance, distribution, and management of respective plants with advanced and sustainable approaches. The book is intended as a key resource for students, botanists and academics in plant science courses. It also serves as a quick guide for horticulture professionals and gardeners dealing with plant diseases and nematode infestations on premises.
Acacias are of considerable social and industrial importance for tropical reforestation and it is expected that about 2 million hectares will be established in Southeast Asia by the year 2000. The acacia species currently of most interest for plantation forestry in the tropics are indigenous to northern Australia, Papua New Guinea and Irian Jaya. Recent reports from Malaysia, Indonesia, Thailand and northern Australia suggest that the future productivity of acacia plantations may be affected by fungal pathogens including leaf spots, shoot blights, stem cankers, heart rot, root rots and gall rusts. During 1995-96 a series of disease surveys was undertaken by forest pathologists in native stands, trials, and operational and social forestry plantings of tropical acacias in Australia, India, Indonesia, Malaysia and Thailand to assess the potential of fungal pathogens as limiting factors to tree growth and productivity and to assess the relative importance of individual fungal pathogens. Tree species included in the surveys were Acacia mangium and A. auriculiformis, on the basis of their current importance as plantation species. A. crassicarpa and A. aulacocarpa were also surveyed as, although they have been planted on a limited scale so far, they are included in provenance and species trials in many locations throughout the region. Scientists who had participated in the project met with research managers of five major Indonesian plantation pulp and paper companies and government business enterprises from 28 April – 3 May 1996 at the base camp of PT Musi Hutan Persada Subanjeriji in southern Sumatra, to present the results of their surveys. This publication is a status report on the diseases of acacias in the several countries based on information presented at the workshop. It provides a benchmark of the current knowledge of the pathology of the four most important Acacia species currently being grown in plantations in tropical areas of Southeast Asia, the Indian subcontinent and northern Australia.
This new edition has been completely revised to provide up-to-date accounts of silvicultural practices, rural development issues, and the wider role that tree-planting plays. The chapters on agroforestry and protection forestry have been virutally rewritten, while throughout the book theimportant place of social forestry is recognized.
Like other agro climatic zones of India, crops in arid region also suffer enormously due to vagaries of plant diseases. Certain agro-climatic conditions favor occurrence and development of these diseases, which often takes a serous form resulting in heavy crop losses. Instances are there when growers have abandoned cultivation of cumin, a cash crop, which suffered heavily due to wilt and shifted to less remunerative or more irrigation requiring crops. Even several folk songs depict the plight of cumin growers. Similarly, concurrent soil moisture and heat stress favor survival and multiplication of soil-borne plant pathogens that causes root rots in many legumes, oilseeds and trees. As arid lands are brought under irrigation, several newer or hitherto unimportant diseases have also became serious. With the burgeoning population pressure, arid region is now confronted with producing more grain and fodder per unit of land. Besides cultivation of drought hardy varieties of crops under improved agronomic practices, management of plant diseases is yet another area, which can accept this challenge to maximize productivity of arid lands. In the present compendium, contributions were invited from experienced research workers working in specialized Institutes. An effort has been made to provide information on the occurrence of major diseases on principal cereals, legumes, oilseeds, spices, horticultural crops, trees, medicinal plants, etc, and on factors influencing their development and practical remedial measures to reduce crop losses.
First Published in 1988, this set offers a comprehensive insight into controlling diseases in plants. Carefully compiled and filled with a vast repertoire of notes, diagrams, and references this book serves as a useful reference for biologists, horticulturalists, other practitioners in their respective fields.
