An overview of the economic importance and control of termites in plantation forestry and wood preservation in Peninsular Malaysia
2000 - IRG/WP 00-10382
Both the plantation forestry and wood preservation industries in the tropical and sub-tropical belts of the world, exemplified by the humid equatorial Peninsular Malaysia, regard termites as major destructive pests of standing trees, various timber products and building timber structures. This paper is a compilation of information on these economically important structural pests encountered in bot...

Fungal decay resistance of Rubber wood treated with heartwood extract of Rosewood
2005 - IRG/WP 05-30367
Alcoholic extract of Dalbergia latifolia heartwood was studied for its toxicity towards wood decaying fungi. Rubber wood blocks were treated with this extract to three different retention levels (0.1%, 0.2% & 0.5%) and the treated wood blocks were assessed for their resistance towards two white rot and two brown rot fungi. Treated blocks showed improved resistance over the control blocks. At 0...

Protection and efficient utilization of plantation grown lesser-known timbers of arid region in India - Acacia tortilis, Prosopis juliflora and Prosopis cineraria
2005 - IRG/WP 05-40321
The plantation-grown timbers are highly susceptible to insects/pests, borers and wood rot fungus. Wood preservatives copper chrome arsenic (CCA) 2% and chloropyriphos 2% solution treated under pressure on three plantation grown timber species viz. Acacia tortilis, Prosopis juliflora and Prosopis cineraria have shown encouraging results in enhancement of shelf life by protection of wood against woo...

Comparative performance of copper azole and copper-chrome-arsenate treated rubber wood in Australian, Malaysian and New Zealand tests sites
2000 - IRG/WP 00-30213
Rubberwood (Hevea brasiliensis) has been used for non-structural products where appearance is important. It has rarely been used for structural uses where preservative treatment is required. In order to evaluate the in-ground durability of preservative-treated rubberwood, test stakes (20 x 20 x 500 mm3) were treated to four retentions of CCA and copper azole (Tanalith® E) and installed in test si...

Anti-sapstain chemicals for diffusion treatment of rubber wood
1986 - IRG/WP 3367
Performance of Sinesto B and Akzo EN 494, two formulated products of alkyl ammonium compounds, was tested as fungicidal additive in the boron solution to control mould and stain during diffusion storage of rubber wood. Sinesto B at 2.0% (a.i.) concentration has given good control over mould and its protection against sapstain was only satisfactory. Akzo EN 494 at 0.7% (a.i.) concentration has give...

Moisture Adsorption Behaviour of Rubber Wood Decayed by Brown and White rot Fungi
2005 - IRG/WP 05-40306
Moisture adsorption behaviour of rubber wood blocks decayed by each brown rot and white rot fungi was studied. The adsorption isotherms of decayed wood were compared with the isotherm of undecayed wood. The wood decayed by brown rot adsorbed less moisture as compared to sound or undecayed wood at all humidity levels. No significant difference was observed in adsorption behaviour of white rot dec...

Decay resistance of coconut and rubber woods. Alternative wood species from Ghana
2006 - IRG/WP 06-10596
With the expanding local and world wide demand for tropical timbers, there is increased interest in the suitability of lesser–used timber species as alternatives for the forest based industries in order to ensure sustainable forest management. In the forests of Ghana, there are quite a number of timber species that are lesser known and have not been adequately used due to the absence of informat...

Needs for wood durability research on planted tree species in the tropics
2008 - IRG/WP 08-10651
The area of forest plantation has been expanding especially in tropical Asia since 1990’s. Most of them are developed for pulp and paper industries and planted with fast growing trees. It is expected that wood from those fast growing trees are also used for value added products such as sawn timber. In order to promote the utilization of fast wood as the resource of value added products, natural...

Natural durability of fast growth plantation Eucalyptus grandis Hill, ex Maiden
2008 - IRG/WP 08-10660
One of the fast growing species cultivated in Uruguay of mayor economical importance is Eucalyptus grandis. Physical and mechanical properties of juvenile and mature wood from different regions have been deeply studied. However, since no scientific data of natural durability of this specie has been reported, natural durability of E. grandis from two sites (Rivera and Rio Negro) was evaluated. Two ...

Natural durability and anatomical features of teak (Tectona grandis) from plantations in Costa Rica
2008 - IRG/WP 08-10671
Teak (Tectona grandis) possesses superior mechanical properties and durability and is thus frequently used as an alternative to impregnated timber in Europe. Demand on teak has resulted in severe exploitation of the tropical teak forests in recent decades, but today the imported timber originates mainly from plantations and is certificated according to the Forest Stewardship Council (FSC) policy. ...

Opportunities and Needs with Treatments for the Protection of Plantation Species
2008 - IRG/WP 08-40438
The future of the wood treating industry lies increasingly on the treatment of wood derived from plantation forests. Plantation softwoods and hardwoods both provide significant opportunity for utilization coupled with protection technologies, but development programs will require much more focus and funding than is currently available. Manufacturing and treating of products from plantation fores...

Natural durability of plantation-grown coast redwood (Sequoia sempervirens) in New Zealand
2014 - IRG/WP 14-10817
There is wide variation in the wood properties of plantation-grown coast redwood in New Zealand. Contributing factors are the seed source, silviculture, growth and age of the trees in the plantation forests. Little is known about how these factors affect the variation of wood properties among and within the trees of New Zealand’s coast redwood forests. Heartwood of plantation-grown coast redwood...

Pest and pathogens threaten the sustainability of plantation forestry: Global research collaboration will define the future
2018 - IRG/WP 18-50341
Global plantation forestry is dominated by intensively managed stands of Pinus, Populus, Acacia and Eucalyptus species. The greater proportion of these plantations has been established in areas where the trees are non-native and have thus been separated from their natural enemies. In all documented cases, these plantations have initially been free of serious pest and disease problems. But as ti...

Enhancing the durability of low durability Eucalyptus plantation species: a review of strategies
2020 - IRG/WP 20-40910
Eucalyptus species native to Australia have shown excellent growth rates, good physical properties and resistance to diseases. As a result, they are widely planted globally for a variety of uses. One negative aspect of many of these faster growing species is that they have a high percentage of low durability heartwood that resists preservative treatment. In Australia, large plantations of these sp...
