While these A. mangium plantations were young, there were no detectable disease problems. Gregor, E.W. Root rot centres in plantations may be recognized by the appearance of slowly enlarging patches of dead and dying trees (see Old et al., 2000). Control of root rot diseases is difficult as the pathogens survive on woody material in the soil. In J. tolerance in tropical It was introduced to Malaysia from Java by seeds, but there are no records of when this took place. The disease is controlled in the nursery with fungicidal sprays, but no control measures are currently applied in the field. Tree mortality generally increases with time in areas where the disease is already present (see Figure). In 2000, the species accounted for over one million ha of landuse in South-East Asia (FAO 2000). Paths to sustainable wood supply to the pulp and paper industry in Indonesia after diseases have forced a change of species from acacia to eucalypts. Forest plantations. Riau Andalan Pulp and Paper, Pekanbaru, Indonesia, Department of Forest Utilisation, Faculty of Forestry, University of Gadjah Mada, Yogyakarta, Indonesia, PT. 1988. The rapid emergence of Acacia mangium as the key industrial plantation species in Indonesia has been followed by the equally rapid emergence of red root rot (Ganoderma philippii) as its potential nemesis. 1999. www.certifiedsourcetimber.co.uk/examples.htm, www.sabah.gov.my/htan/new/Malay/sumber_hutan/b_history.htm, www.forestry.sarawak.gov.my/forweb/sfm/fdw.fplntn.htm. : ecology, silviculture and productivity 3 2.4. Of the diseases identified in A. mangium plantations, * Author for correspondence. As a consequence, and on severely affected mineral soils in equatorial tropical environments in particular, A. mangium may no longer be capable of producing commercial yields after three rotations. Of the diseases identified in A. mangium plantations, * Author for correspondence. Root rot has become the most economically damaging disease of this species with high tree mortality rates observed during second and third rotations. Partly as a result of the heart rot problem, A. mangium is no longer a popular forest plantation species in Peninsular Malaysia, although it is still planted for pulp and paper production in the eastern Malaysian states of Sabah and Sarawak. Mahmud, S., Lee, S.S. & Ahmad, H.H. & Lee, S.S. 1994. Most damage occurs on new foliage in the upper crown. wilt and canker – a disease that compromises the growing of commercial However, acacia plantations throughout Vietnam have been widely infected by Ceratocystis manginecans wilt disease, posing a serious threat to … Old, K.M., Lee, S.S., Shama, J.K. & Yuan, Z.Q. FRIM Research Pamphlet, 114: 1-15. & Brandeis, T. 2003. The disease appears to be spreading in this plantation, affecting both seedlings in the nursery and mature trees in the field. Internet document: www.forestry.sarawak.gov.my/forweb/sfm/fdw.fplntn.htm. Native to northern Queensland, Australia, Papua New Guinea and Indonesia. As a result, some sources have described A. mangium as an alien weed and invasive species, believing that it will diminish the rejuvenation potential of the original biota and invade highland secondary forests and rain forests (Certified Source Timber Programme, 2004). Root rot is the most important disease affectingAcacia trees,includingA. In late 1992, an epidemic outbreak of gall rust was reported from F. moluccana plantations in Sipitang on the west coast of Sabah. Agents on Acacia Name: Speiredonia retorta (Lepidoptera: Noctuidae) Common name: Comma moth Host: Acacia mangium, Albizzia spp. Signs and identification of fungal root‐rot pathogens in tropical Eucalyptus pellita plantations. Because of the observed impact of heart rot on timber quality, the Ministry of Primary Industries of Malaysia imposed a temporary moratorium on further planting of A. mangium in 1992. -based plantations in the tropics Abstract. Acacia may need occasional pruning during the dry months. Sarawak Forest Department.

Research Information Series on Ecosystems, Special Issue. Sexuality and mating types of Ganoderma philippii, Ganoderma mastoporum and Ganoderma australe, three basidiomycete fungi with contrasting ecological roles in south-east Asian pulpwood plantations. Plant Disease is the leading international journal for rapid reporting of research on new, emerging, and established plant diseases. Acacia mangium is a major plantation species in the humid tropical lowlands of Asia. In this experiment, 100‐tree plots were established in commercial plantings of A. mangium at five sites which represented the range of growing conditions used for plantation establishment in Indonesia. Its ability to rapidly colonize roadsides, abandoned, degraded or open areas and marginal lands is well known, and like its close relative Acacia auriculiformis, A. mangium is now a common feature of the landscape in Malaysia and many other Southeast Asian countries. mangium, in The current status of root diseases in Acacia mangium Willd.

Flood, P.D. Root rot has become the most economically damaging disease of this species with high tree mortality rates observed during However, A. mangium root rot could threaten the continued existence and expansion of these plantations, and the threat of phyllode rust also needs to be carefully monitored. The past three decades have been turbulent times for forest plantations in Malaysia. Its aim is to synthesise information about this fungal pathogen that can be used to Acacia mangium is an evergreen fast-growing tropical tree, which can grow up to 30 m tall and 50 cm thick, under favorable conditions. If you do not receive an email within 10 minutes, your email address may not be registered, Acacia mangium is the main plantation species in Vietnam, accounting for more than 54% of the plantation forest estate. The average rate of disease development was about 0.3% per month, and average time from infection to tree death was conservatively estimated at around 1 year. In K.M. Recently, several Ceratocystis isolates were collected from wilting A. mangium in plantations in Indonesia. There has been some concern about the weedy nature of Acacia mangium and its potential to become an invasive species. Timber with heart rot is not suitable for general purposes such as construction because of loss of structural strength and poor recovery of high-value products during processing. Of these diseases, heart rot is The origin of the disease in the F. moluccana plantations in Sabah is not known. CIFOR Special Publication. Later, in the continued absence of local pulp and paper mills, there was an intention to use Pinus spp. FRIM Research Pamphlet, 114: 16-21. Old, S.S. Lee & J.K. Sharma, eds. Acacia mangium honey. & Sim, H.C. 1994. If you live near an acacia mangium forest than beekeeping is guaranteed success. When the moratorium was lifted in 1994 the government had stopped establishing new forest plantations and was encouraging the private sector to take up the enterprise. The Disadvantages of an Acacia Plant. Journal of Tropical Forest Science, 6: 37-47. Unsound knots and wane (defective edges or corners on a plank of wood) are prevalent in sawn timber from A. mangium affected by heart rot, which reduces yield, especially of small logs (Ho and Sim, 1994). Of the species planted, nitrogen-fixing A. mangium appeared most promising, partly because of its far superior growth, wide site suitability, multiple uses and supposed lack of serious pest problems, but especially because it was easy to plant large areas as planting material was not difficult to obtain. Insect pests and diseases routinely affect the health of trees, and major outbreaks can give catastrophic environmental and economic impacts. Similarly, Sabah Softwoods was established in Sabah in 1974 to plant Pinus caribaea for the pulp industry, but slow growth and seed supply problems led to replacement of the pines with A. mangium, F. moluccana, G. arborea and Eucalyptus deglupta.
