Book Description
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.

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

Book Description
This manual summarises information on the ecology and silviculture of the species Acacia mangium Willd, with an emphasis on Vietnam. It also encompasses growth and yield data from published sources, as well as collected from sites under smallholder industrial plantations in Phu Tho Province, Vietnam. This manual is 1 of 5 that guide smallholder tree planting of 5 selected tree species in Vietnam. The other 4 species are: Acacia hybrid, Cinnamomum parthenoxylon (Jack) Meisn, Erythrophloeum fordii Oliver and Eucalyptus urophylla S.T. Blake. The Government of Vietnam is carrying out a large-scale reforestation programme, with the aim of improving local livelihood security, environmental sustainability and industrial wood supply. Smallholders are involved in plantation timber production through various schemes. Generally, these reforestation efforts have been effective, even though smallholders often lack the appropriate technical knowledge and management skills. Consequently, the quality and quantity of wood products may be suboptimal. The productivity of smallholder plantations can be improved by enhancing smallholders management knowledge and skills, including species selection (site matching), silvicultural management to produce high quality products, and pest and disease management.

Book Description
The fungal genus Ganoderma includes around 80 currently recognized species that are widely distributed in temperate, subtropical and tropical regions, and cause disease in a range of economically important perennial crops and tree-like plants. Ganoderma root and lower stem rots have a significant impact on yields from crops including oil palm, coconut, beverage crops, Acacia and rubber. The identification of species responsible for stem and butt rots is often ambiguous as closely related species may only be distinguished by subtle morphological differences. Within species there can be considerable morphological plasticity and this can make morphology-based identification difficult, particularly for species described from a single specimen. Molecular techniques are helping to slowly resolve Ganoderma taxonomy but it will be some time (if ever) before the taxonomy is fully resolved. This book brings together information on Ganoderma species that are reported to be responsible for crop diseases in tropical and sub-tropical agriculture and covers taxonomy, biology, genetics, aetiology, epidemiology and control. This book is an essential resource for researchers in Ganoderma in crop science and tropical agriculture, as well as practitioners and industry.

Book Description
To meet the challenge of feeding ever increasing human population, efficient, economical and environment friendly disease control methods are required. Pests are responsible for heavy crop losses and reduced food supplies, poorer quality of agricultural products, economic hardship for growers and processor. Generally, chemical control methods are neither always economical nor are they effective and may have associated unwanted health, safety and environmental risks. Biological control involves use of beneficial microorganism to control plant pathogens and diseases they cause and offers an environmental friendly approach to the effective management of plant diseases. This book provides a comprehensive account of interaction of host and its pathogens, induced host resistance, development of biological control agents for practical applications, the underlying mechanism and signal transduction. The book is useful to all those working in academia or industry related to crop protection.
