Eucalyptus globulus. Impregnability in relation with plantation and crop
1992 - IRG/WP 92-2402
Eucalyptus globulus Lasill is currently classified in Pr EN 350 on the basis of the characteristics of the first log. In practice, there are usually several following crops of branches developped on each stump in plantations. Up to a diameter of 8 cm, round wood of 2nd crop and further crops present a maximum of sapwood and characteristics which differ significantly from the basic classification a...

Need to develop processing technologies (for value addition) of the species evaluated for their properties and uses
2005 - IRG/WP 05-40307
The demand of timber in India for different industrial as well as domestic applications is ever increasing mostly due to urbanization and industrialization. This demand can only be met either from the imported timber or from the plantation resources outside the reserved and natural forests. There are a number of timber species grown under plantation forestry have their heartwood refractory to any ...

Field tests of molybdenum and tungsten baits for termite control
2004 - IRG/WP 04-30345
Molybdenum and tungsten compounds are slow acting to termites and show a high termiticidal efficacy. In our previous papers, we have already reported that those are useful as termiticidal ingredients of bait formulations.
The demand for natural rubber is still on the increase. However some kinds of termites inhabiting rubber plantations damage rubber trees and pose a serious threat.
To cope with...

Pole yield of some softwood and hardwood species grown in Bangladesh
1999 - IRG/WP 99-40143
Growth study on 9 timber species planted in Bangladesh soils revealed that 6 species fall under wooden electric pole yield group-A, produce 33% poles within 10 years, another 33% within 15 years and additional 33% within 20 years of rotation. Two species under yield group-B produce 33% poles within 15 years and another 33% within 20 years. One species under yield group-C produce at best 25% poles ...

Alternatives to CCA-treated Pinus radiata as vineyard posts
2004 - IRG/WP 04-50212
An estimated 10 million trellis posts per year are used in Australian vineyards and about 75% of these are CCA-treated Pinus radiata. CCA-treated Pinus radiata posts are brittle and at times in short supply. Use of some products containing CCA is being restricted in Australia. Recently, plantation forestry has expanded rapidly for disposal of industrial and irrigation wastewater. Thinnings from th...

The relationship between basic density and liquid absorption in fast, plantation grown 8 Year Old Eucalyptus pellita and E. Urophylla
2002 - IRG/WP 02-40220
The liquid absorption characteristics of 8 year old Eucalyptus pellita and E. urophylla were studied in order to gain insight into the treatability of this young, fast grown eucalypt plantation resource. The trees were grown in an experimental plantation trial near Innisfail in northeast Queensland.
The study demonstrated that average sapwood basic density in young plantation grown E. pellita a...

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...

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...

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...
