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). Internet document: www.sabah.gov.my/htan/new/Malay/sumber_hutan/b_history.htm. However, no figures are available on the impact of the disease in the plantations. ), approximately 60 percent has been planted with the fast-growing exotic A. mangium. 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. Crown colour and density were poor predictors of either the presence or severity of infections. Forest Ecology and Management 190 (2004) 273–280 Incidence of heartrot in harvest-age Acacia mangium in Indonesia, using a rapid survey method K.M. Acacia Discoloration and heart rot of Acacia mangium Willd. plantations in Indonesia Old, K.M., Lee, S.S., Shama, J.K. & Yuan, Z.Q. The disease is controlled in the nursery with fungicidal sprays, but no control measures are currently applied in the field. The origin of the disease in the F. moluccana plantations in Sabah is not known. Within a year, the disease had spread over 450 ha, causing wilting of gall-bearing branches, severe dieback, stunting and death of trees. 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). Furthermore, A. mangium plantations have been located in natural forests in Malaysia, yet there have been no incidences where the species has been found to invade undisturbed sites. Species of Ceratocystis are well-known wound related pathogens of many tree species, including commercially planted Acacia spp. Acada mangium is one of the major fast-growing hardwood species used in plantation forestry programmes throughout Asia and the Pacific. Journal of Tropical Forest Science, 6: 37-47. This is a list of Acacia species (sensu lato) that are known to contain psychoactive alkaloids, or are suspected of containing such alkaloids due to being psychoactive.The presence and constitution of alkaloids in nature can be highly variable, due to environmental and genetic factors. However, the moratorium was lifted in 1994 when further studies showed that although the defect had a serious effect on wood used for construction and appearance grades, it was of little significance in the production of pulp and paper or composite wood products (Gregor, 1993). The current status of root diseases in Acacia mangium Willd. Inclusion of resistant strains in Acacia improvement programmes would appear to be the most feasible approach to combating this disease in the long term. The effective management of all tree health problems depends on their early detection. In Peninsular Malaysia and Indonesia the disease appears to be associated with several basidiomycete fungi (Lee and Noraini Sikin, 1999; N. Bougher, personal communication). The past three decades have been turbulent times for forest plantations in Malaysia. In addition,Eucalyptus spp. Agents on Acacia Name: Speiredonia retorta (Lepidoptera: Noctuidae) Common name: Comma moth Host: Acacia mangium, Albizzia spp. Diseases of species and provenances of acacias in West and South Kalimantan, Indonesia. Human-dominated tropical landscapes: a new mix of alien and native species coexist in harmony. Large numbers of trees have been killed in ten-year-old plantations in Peninsular Malaysia (Ito, 1999; Lee, 2000). The hybrid’s branching behaviour differs from Acacia mangium and Acacia auriculiformis in that the tree has many small, light branches that can be easily pruned. koae, by drenching root systems with standardized spore suspensions in sterile distilled water. In Integrated report on the Multi-Storied Forest Management Project in Malaysia (1991-1999). Forest plantations. Kuala Lumpur, Malaysia, Forestry Department Malaysia, Perak State Forestry Department and Japanese International Cooperation Agency. Avoid pruning leafy, green areas and trim only dead growth. for poles and timber, but this did not come about because planting material was difficult to obtain in Malaysia. Ceratocystis wilt and canker disease has severely compromised the profitability of Acacia mangium plantations in Southeast Asia. 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. Research Information Series on Ecosystems, Special Issue. & Old, K.M. Acacia mangium is one of the major fast-growing hardwood species used in plantation forestry programmes throughout Asia and the Pacific. Jakarta, Indonesia, CIFOR. Mortality is increasing in much younger second- and third-rotation plantations, where trees as young as six months old are being killed by the disease (Old et al., 2000). In the 1970s exotic pines (Pinus spp.) Abstract. 1997. A. mangium, planted on a 15-year rotation for production of general-utility timber, came to constitute the largest area of forest plantations in the country. Beehives in Acacia mangium plantations produce up to 110 kg or 242.5 lbs of honey per hive per year, which is important for local economies and employment. Paraserianthes falcataria), also called albizia, is a fast-growing native of the Moluccas, Papua New Guinea and the Solomon Islands. Root rot is the most important disease affectingAcacia trees,includingA.

Acacia mangium Willd. Preliminary studies have shown that leaf diseases, root rot, pink disease and heart rot occur in A. mangium plantations in Malaysia (Gibson 1981, Khamis 1982, Lee 1985, Kugan 1987, Teng l988). 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. 1988. Gall rust disease of Albizia falcataria (L.) Beck. Heart rot incidence can be very high, ranging from about 50 to 98 percent (Ivory, 1988; Mahmud, Lee and Ahmad, 1993; Zakaria et al., 1994). Damage/symptoms: First and second instar larvae feed on soft, immature foliage, making small holes in the leaves. Acacia plantations established in this country amounted to approximately 1 million ha in 2006 (Arisman and Hardiyanto 2006). Studies are under way to find disease-tolerant or disease-resistant trees for a breeding programme. PESTS AND DISEASES A. mangium is affected by heart rot caused by white fungi. Lee, S.S. 2000. Therefore, there is always a need for vigilance and regular disease monitoring and/or surveys so that any new diseases may be rapidly detected and suitable management or control measures implemented without delay. Systemic fungicide application may be feasible in the nursery but is impractical and uneconomical in large-scale plantations. mangium, in The Sabah Forest Industries (SFI) integrated pulp and paper mill began commercial production in 1988 and mainly relied on hardwood timber from the natural forest for its raw materials, but SFI also planted A. mangium and Eucalyptus spp. 2004. Ivory, M.H. Poster presented at the International Congress of Plant Pathology (ICPP) 2003, Christchurch, New Zealand, 2-7 February. In 2000, Sabah had approximately 75 000 ha of A. mangium plantations (Jabatan Perhutanan Sabah, 2004) and Sarawak about 4 000 ha (Sarawak Forest Department, 2004). & Razali, A.K. were favoured as plantation species with the objective of pulp and paper production. In late 1992, an epidemic outbreak of gall rust was reported from F. moluccana plantations in Sipitang on the west coast of Sabah. Signs and identification of fungal root‐rot pathogens in tropical Eucalyptus pellita plantations. Lugo, A.E. The disease appears to be spreading in this plantation, affecting both seedlings in the nursery and mature trees in the field. Special Issue: Root Rot in South‐East Asian Plantations. Another disease with potentially devastating effects is a phyllode rust associated with the fungus Atelocauda digitata. Pink disease, caused by the basidiomycete fungi Corticum salmonicolor, has been known to infect 17% of A. mangium in Malaysia. Ho, K.S. : ecology, silviculture and productivity 3 2.4. -based plantations in the tropics Additionally, watch for pests such as aphids, thrips, mites and scale. Role of site in the mortality and production of This guide will help readers recognize symptoms of ill health in trees and understand their general significance. Control of root rot diseases is difficult as the pathogens survive on woody material in the soil. In K.M. 1988. If you live near an acacia mangium forest than beekeeping is guaranteed success. 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. Acacia mangium, a fast-growing tree native to parts of Indonesia, Papua New Guinea and Australia, has been cultivated outside its native environment and introduced into humid tropical lowland regions of Asia, South America and Africa over the last few decades. Sarawak Forest Department. Identification of basidiomycete fungi in Indonesian hardwood plantations by DNA barcoding. are increasingly planted in Indonesia with this resource currently being utilised in pulp and rayon production. It is a multipurpose tree used in agroforestry, forestry and for restoration of degraded lands. Recently, several Ceratocystis isolates were collected from wilting A. mangium in plantations in Indonesia. Tree mortality increased more or less linearly with time and led to the progressive coalescence of initially discrete disease gaps. Alien and native species have been known to coexist in harmony without any deleterious effects on sites or the capacity to deliver services to society, and in some cases such new forests can reverse site degradation processes (Lugo and Brandeis, 2003). Gall rust of F. moluccana is definitely a very serious and devastating disease that requires urgent attention. Crown condition declines and growth rate is poor. In addition, other as yet unknown diseases could appear as areas under forest plantations expand and other tree species are planted. 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. This disease has been present for some time in its native habitat in Australia and in Acacia plantations in Java, Sumatra and Kalimantan in Indonesia (Hadi and Nuhamara, 1997); however, until recently it was thought to be absent from Malaysia. Acacia mangium is the main plantation species in Vietnam, accounting for more than 54% of the plantation forest estate. Musi Hutan Persada, Palembang, Indonesia, PT. Plant Disease is the leading international journal for rapid reporting of research on new, emerging, and established plant diseases. 1993. Cristavao, C.S. Family Fabaceae (Mimosoideae). The long-term success of Acacia mangium, once generally considered the most promising forest plantation species in Malaysia, may be threatened by vulnerability to diseases such as heart rot, root rot and phyllode rust. in Sabah. Acacia mangium is in subgenus Phyllodinae, a group containing in excess of 900 species (Maslin and McDonald, 1996). Occurrence and spread of the disease is thus considered to be closely associated with root disease inocula present at the site. It may be just a matter of time before it spreads to the existing disease-free A. mangium plantations in Peninsular Malaysia and other neighbouring countries in Southeast Asia. The past three decades have been turbulent times for forest plantations in Malaysia. The most common type of heart rot found in A. mangium is a white fibrous rot which may occur as small pockets or throughout the length of the heartwood. The trees are grown on a rotation of about seven years for the production of chips and pulp. 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. In Proceedings of the Seminar on the Potential of Acacia and Other Plantation Species, p. 44-55. Old, S.S. Lee & J.K. Sharma, eds. Heavy infestation results in deformation of the foliage, defoliation, stunted form and reduced growth. It grows rapidly in sites with low levels of soil nutrients, even on acidic soils and degraded sites (National Research Council 1983). Root rot has become the most economically damaging disease of this species with high tree mortality rates observed during The relationship between occurrence of root rot and soils is at present unclear and warrants further study. ABSTRACT. There has been some concern about the weedy nature of Acacia mangium and its potential to become an invasive species. Internet document: www.forestry.sarawak.gov.my/forweb/sfm/fdw.fplntn.htm. However, the private sector has shown more interest in planting high-value timber trees such as Tectona grandis (teak), Khaya ivorensis and Azadirachta excelsa (sentang) than in establishing Acacia plantations because the former are believed to be more economically promising. Root rot has become the most economically damaging disease of this species with high tree mortality rates observed during second and third rotations. Working off-campus? So far, these interactions have never been evaluated in the Acacia and Eucalyptus forest planted on infertile soils in the Congolese coastal plains. 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. However, the volume of wood affected is usually rather small; mean volume loss is only about 1 percent of merchantable volume. Flood, P.D. & Brandeis, T. 2003. Acacia On the peninsula no new significant Acacia plantations have been established apart from those previously planted by government projects. Forest pathology consultancy final report. Journal of Tropical Forest Science, 11: 240-254. The focus of this review is on Ceratocystis wilt and canker disease in Acacia trees. 1990. Most damage occurs on new foliage in the upper crown. Acacia mangium is an evergreen fast-growing tropical tree, which can grow up to 30 m tall and 50 cm thick, under favorable conditions. plantations, little is known of the potentially damaging diseases of A. mangium and their control. Of these diseases, heart rot is However, A. mangium continues to be planted in Sabah and Sarawak for planned pulp and paper production, which is not influenced significantly by heart rot. and other legumes. Structural host responses of Acacia mangium and Eucalyptus pellita to artificial infection with the root rot pathogen, Ganoderma philippii. 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.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 … Insect pests and diseases routinely affect the health of trees, and major outbreaks can give catastrophic environmental and economic impacts. FRIM Research Pamphlet, 114: 1-15. 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. A. mangium is able to revegetate marginal and degraded areas, thereby improving the site for subsequent colonization by other plant and animal species. tolerance in tropical Later, in the continued absence of local pulp and paper mills, there was an intention to use Pinus spp. Where mortality resulting from root rot is high, planting of resistant Acacia cultivars or alternative species may have to be considered. 1993. It is not inconceivable that the infection of the Sabah plantations in 1992 had its origin in the Philippines, given the proximity of Sabah to Mindanao, the dispersal of the spores by wind and the high volume of traffic between the two regions. Sawn timber from Acacia mangium affected by heartrot. Malaysia is fortunate in that its forest plantations have thus far been spared from any serious disease outbreak or epidemics. & Lee, S.S. 1994. Recently, several Ceratocystis isolates were collected from wilting A. mangium in plantations in Indonesia. In 1999, this disease was reported to be widespread in a large, previously gall rust free F. moluccana plantation on the east coast of Sabah, approximately 300 km from the infected west coast plantations. Acacia may need occasional pruning during the dry months. The journal publishes papers that describe translational and applied research focusing on practical aspects of disease diagnosis, development, and management in agricultural and horticultural crops. Acacia mangium is a fast‐growing tree species. Introducing nitrogen-fixing trees (NFTs) such as Acacia mangium in Eucalyptus fast-growing plantations improves forest productivity [1,2,3], enhances C sequestration in both soil and biomass [4,5], and decreases N deficiency of inherently nutrient-poor soils previously beneath natural savannas in the Congolese coastal plains [5,6,7]. E-mail: karen.barry@utas.edu.au Trees with more than four dead/missing neighbours had a >50% chance of being dead by the following monitoring. Unlike 1999.

Kuala Lumpur, Malaysia, Silviconsult Ltd/Compensatory Plantation Unit and Federal Forestry Department of Peninsular Malaysia. – some preliminary results. Tree mortality generally increases with time in areas where the disease is already present (see Figure). Disease threatens exotic plantation species in Sabah, Malaysia. Its aim is to synthesise information about this fungal pathogen that can be used to Gregor, E.W. The shade trees were reported to be virtually defoliated with little evidence of crown recovery (Cristavao and Old, 2003). Journal of Tropical Forest Science, 1: 170-177. Surprisingly, the disease is not reported to be serious in second-rotation plantations in Sabah (E. Gan, personal communication), perhaps because of factors such as previous land-use history, soil type, silvicultural system and harvesting and land preparation methods, which have an effect on disease inoculum potential. 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. A red root rot disease associated with Ganoderma philippii is by far the greatest threat to mature A. mangium plantations. 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. Diseases of tropical acacias, p. 23-46. Species‐specific PCR for rapid identification of Ganoderma philippii and Ganoderma mastoporum from Acacia mangium and Eucalyptus pellita plantations 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. However, as the plantations grew they turned out to be prone to a number of diseases. Learn more. Leaves of affected trees turn pale green and are much reduced in size and number. Please check your email for instructions on resetting your password. Hadi, S. & Nuhamara, S.T. Ceratocystis Promoting plantation grown timber. The disease is caused by a species of the rust Uromycladium, most likely U. tepperianum. & Dayan, M.P. 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). Young shoots may wilt and trees in advanced states of root rot are very prone to wind throw. Spores of the fungus are wind dispersed and it would appear that the disease is spreading to Malaysia from neighbouring Kalimantan. 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. Between 1999 and 2002 this disease was found throughout all the coffee-growing districts of East Timor, where F. moluccana is planted as a shade tree for coffee plants. . If you do not receive an email within 10 minutes, your email address may not be registered, Zakaria, I., Wan Razali, W.M., Hashim, M.N. 2003. An A. auriculiformis x A. mangium hybrid is reputed to be less susceptible to heart rot than A. mangium, but there are few data to support that theory. Management of basidiomycete root‐ and stem‐rot diseases in oil palm, rubber and tropical hardwood plantation crops. Jakarta, Indonesia, CIFOR. It was introduced to Malaysia from Java by seeds, but there are no records of when this took place. The hybridAcaciaalso showed more resistance to heart rot disease - a diesease that occurs in A. mangium and it was observed that the species grows vigorously resisting heart rot disease in the forest plantations (Banik and Islam 1996). Ceratocystis wilt and canker disease has severely compromised the profitability of Acacia mangium plantations in Southeast Asia. The incidence of heart rot in Acacia mangium plantations in Peninsular Malaysia. FRIM Research Pamphlet, 114: 16-21. Products and market potential for Acacia and other plantation species. No figures are available as to how production is affected as large-scale assessment of the impact of the disease has not been carried out. Although the initial panic was a reaction to heart rot, A. mangium is susceptible to other more serious diseases which impair growth or cause tree mortality. Fungi associated with heart rot of Acacia mangium trees in Peninsular Malaysia and East Kalimantan. Barrya,b,*, R.S.B. The aim of this study was to identify these 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. New rapid disease detection techniques, selection of disease-resistant plant material and an effective information exchange network within the region also need to be developed to aid in this effort. and you may need to create a new Wiley Online Library account. This disease is very serious in parts of neighbouring Indonesia, where mortality is high (about 20 percent) (I. Ragil, unpublished data). It is mainly planted in large monocultures for pulpwood in South-East Asia. Arara Abadi – Sinar Mas Forestry, Pekanbaru, Indonesia. Eusebio, M.A., Sinohin, V.O. Plenary lecture presented at Biotic Interactions in the Tropics: A Special Symposium of the British Ecological Society and The Annual Meeting of the Association for Tropical Biology and Conservation, Aberdeen, UK, 7-10 July. Falcataria moluccana (Leguminosae: Mimosoideae) (syn. & Sim, H.C. 1994. The overall impact of the disease has yet to be assessed and at present there is no specific method of control apart from destroying infected plants. It has become a major industrial plantation species in Malaysia, Thailand and Indonesia. F. moluccana plantations in Malaysia are largely confined to the state of Sabah, where they cover an estimated 12 000 ha (Jabatan Perhutanan Sabah, 2004). Ganoderma diseases of perennial crops, p. 71-79. Infected seedlings become stunted and die after several months while infected trees in the field have sparse crowns and produce fewer flowers and pods. The Disadvantages of an Acacia Plant. Riau Andalan Pulp and Paper, Pekanbaru, Indonesia, Department of Forest Utilisation, Faculty of Forestry, University of Gadjah Mada, Yogyakarta, Indonesia, PT. In a long-term root disease survey in A. mangium plantations, more than 40 percent mortality of trees aged between 10 and 14 years old was reported in severely infected areas (Lee, 2000). Certified Source Timber Programme. The aim of this study was to characterize the botryosphaeriaceous fungi associated with decline symptoms observed in Acacia mangium … Of the diseases identified in A. mangium plantations, * Author for correspondence. Kuala Lumpur, Malaysia, Malaysian Timber Industry Board and Asian Development Bank. Native to northern Queensland, Australia, Papua New Guinea and Indonesia. Species of Ceratocystis are well-known wound related pathogens of many tree species, including commercially planted Acacia spp. A survey of heart rot in some plantations of Acacia mangium Willd. Most acacia plants (Acacia spp.) Although the tree is disease-resistant, it can sometimes be affected by a fungal disease known as anthracnose. Prior to the moratorium on A. mangium planting imposed because of heart rot in 1992, all A. mangium plantations in Peninsular Malaysia were developed by the federal government.
