A medium for mass culturing of a bamboo boring beetle Dinoderus minutus Fabricius
1983 - IRG/WP 1182
The bamboo is a traditional product of Japan. But its susceptibility to insects is one of the most important problems. The author has found that for the determination of the effectiveness of insecticides it is very easy to obtain sufficiently numerous adults of Dinoderus minutus by using Buckwheat Cake. The Buckwheat Cake is prepared with buckwheat flour and thin paper. The author has previously f...

Treatment of fresh green round bamboos culms (Dendrocalamus strictus) by sap-displacement (wick) method
2005 - IRG/WP 05-40311
Sap displacement method has great potential for treating short length bamboos as it does not require any technical equipment. The process is simple and large nos. of bamboos can be simultaneously treated in relatively short period. There is no wastage of chemicals as the remnant solution reused. Bottom ends and middle portion had better treatment in compared to lop end portion. With increasing len...

Biofouling and bioresistance of bamboo in marine environment
2003 - IRG/WP 03-10482
Proudly known as “green gold” and popularly called as “poor man’s timber”, bamboo is closely interwoven with the life of scores of people around the globe because of its versatile qualities and desirable strength properties as a structural material. It is used for innumerable purposes both on land and in water including seas and brackishwater bodies. "Presently, bamboos constitute an i...

Penetration analysis of two common bamboo species - borak and jawa of Bangladesh
2002 - IRG/WP 02-40247
Preservative treatment of two bamboo species, namely borak (Bambusa balcooa Roxb.) and jawa (Bambusa salarkhanii Alam) was carried out with chromated copper boron (CCB) preservative by dipping method. The variation in preservative penetration between the two different species was determined. It was found that preservative penetrates into borak quicker than into jawa and easier into air-dried bambo...

Scientific development for prolonging the service life of timbers by impregnating with creosote or organic solvent type preservatives in which additive has been incorporated
1977 - IRG/WP 382
Chemically impregnated wood has played a prominent part in the Telephone and Electricity Distribution Industry during the past century and there is no doubt that it will play an equally prominent part in the future. The reasons why wood poles and wooden, structures predominate, are that when adequately chemically impregnated with a recognised timber preservative to ensure the expected service life...

Long-term performance of a "wax" type additive for use with water-borne pressure preservative treatments
2000 - IRG/WP 00-40159
Field performance results are updated for matched CCA treated decking boards with and without an emulsion water repellent additive incorporated with the initial pressure treatment. Decks have been exposured for over 9 years in Harrisburg, NC. Boards were evaluated for in-service and laboratory performance for water repellent efficacy, as well as additive loadings in the boards after this exposure....

Heat treatment of bamboo
2001 - IRG/WP 01-40216
Bamboo is a fast growing material with remarkable mechanical properties. In many tropical and subtropical countries bamboo is available in suitable dimensions for a reasonable price. Therefore it is used for many purposes which range from the basket production up to the industrial production of parquet or paper. However, bamboo is known as susceptible to fungal or insect attack and it is difficult...

Biocides - Efficacy assessment and doses for wood preservatives (product type 8). Local/geographical aspects. Termite control as case study
1999 - IRG/WP 99-20181
Currently, the efficacy of a wood preservative, as biocidal product type 8, is assessed as a ‚critical value' (CV), an efficient dose (retention in wood at a given depth of penetration). CVs are planned to be adapted for exposure to basic target organisms (5 hazard classes) and additional requirements concerning the occurrence of local target organisms in relation with climate, building...

An effective preservative treatment of borak bamboo (Bambusa balcoona Roxb.)
1996 - IRG/WP 96-40070
Adequate penetration and retention of CCA and CCB has been obtained in predried Borak Bamboo (Bambusa balcooa Roxb.), aboundantly grown in Bangladesh, with Full Cell Pressure Process. The treated bamboo can be used as building materials, the sufficient treatability ensured its long term best utilization at ground contact and indoors. Which will keep the environmental & socio economical conditi...

Literature survey on the permanence and distribution of salt-type wood preservatives
1969 - IRG/WP III 1B
The objective of this survey is generally to review some of the more important published work dealing with the distribution and permanence of salt-type waterborne wood preservatives in treated timber. The survey is limited to the major chrome-containing formulations and the classification system proposed by Becker (1964) has been adopted throughout.
CK - chromium, copper (copper, chrome); CKA - c...

Effect of felling time related to lunar calendar on the durability of wood and bamboo
-Fungal degradation during above ground exposure test for 2 years- (Preliminary report)
2005 - IRG/WP 05-20311
Current study was carried out to know whether the felling time of trees and bamboos based on lunar calendar affects natural durability of felled wood-bamboo or not. Each of one sugi (Cryptomeria japonica) tree of 28 years old and one Moso bamboo (Phyllostachys heterocycla) of around 3 years old was cut 12 times between February and December in 2003. Six sets of sugi tree and bamboo were felled in ...

The use of image analysis to quantify soft rot decay
1992 - IRG/WP 92-2410
Image analysis techniques can provide quantitative information from visual images. As part of a wider interest in decay assessment methods we have investigated the application of image analysis techniques for quantifying soft rot decay by Chaetomium globosum in transverse sections of birch wood and bamboo. A method for reducing contamination of the section (and image) by the fungal hyphae and of s...

Non Toxic Remedial Treatment of Bamboo Structures/Furniture
2010 - IRG/WP 10-40516
Molds and beetles often attack bamboo furniture and structures when used in untreated or inadequate preservative treatment. Remediation or eradication of infestation often involves expensive chemicals (fumigants) and specialized methods, which are not available in villages. Novel inexpensive methods using easily available chemicals were developed for controlling such infestations. Whereas applicat...

Comparison of the effect of different soil sources on the type and rate of decay of CCA-treated pine exposed in a soil-bed
1984 - IRG/WP 2213
The types of decay observed in CCA-treated pine posts in horticultural situations in New Zealand can be reproduced using a soil-bed exposure. Radiata pine stakelets, untreated or treated to 1.4, 2.7, or 5.4 kg/m³ with Tanalith NCA, were exposed to six different soil sources. The local nursery soil used for all standard laboratory tests was found to represent the greatest decay hazard to untreated...
