Japanese standardized methods for testing effectiveness of chemicals against termite attack
1986 - IRG/WP 1290
Japanese standard termiticide testing methods are reviewed. There are some standard testing methods provided by Japan Termite Control Association (JTCA) and Japan Wood Preserving Association (JWPA), though most of them are common to two organizations. Methods were standardized between JTCA and JWPA in 1981, and more recently examining system was established for authorizing efficacy of wood preserv...

Laboratory bioassays with termites – The importance of termite biology
2005 - IRG/WP 05-10550
Subterranean termites are frequently used in bioassays to asses the effectiveness of insecticides or the resistance of materials. Termites which appear to be vigorous with high inherent levels of activity are often relied upon, yet at the end of the experiments survival may be very unsatisfactory, even in the favourable environment of controls. Consequently, results from such bioassays may be mean...

Laboratory method for testing the effectiveness of soil termiticides
1992 - IRG/WP 92-1561
In France, the protection of buildings against termites is based on a chemical treatment of wood, soil and walls. Because of the withdrawal of aldrin from the market, the need of new soil termiticides has appeared. Therefore, a laboratory method derived from Cymorek's method has been developped to assess their effectiveness. Some points are developed like the type of soil, the number of t...

Deltamethrin effectiveness against subterranean termite attack on wood under natural conditions
1989 - IRG/WP 1407
On fighting subterranean termites on wood, out of ground contact, the synthetic pyrethroid Deltamethrin shows positive aspects such as its efficiency and low mammalian toxicity. To evaluate its performance in conditions very similar to those in service use, specimens of Pinus sp were treated with solutions of Deltamethrin diluted in "white spirits" at 0.005% (w/w) and 0.01% (w/w) and exposed in a ...

Effectiveness of "Gang-Nail" plates in preventing splitting of Eucalyptus poles and Brazilian hardwood sleepers
1984 - IRG/WP 3262
This paper presents the results of some tests carried out with an anti-splitting device, placed on the end surfaces of Eucalyptus spp utility poles and Brazilian hardwood sleepers at the beginning of an air-drying period. The type of device used, a "Gang-Nail" plate, reduces significantly the splits at the end-surface of poles, but reduces only a little the splits occurring in sleepers....

The evaluation of synergistic effects of chemicals on fungicidal efficacy in crossed-paper tests
1991 - IRG/WP 2383
The mixing effects of wood preservatives were evaluated using the crossed-paper technique. Two filter paper strips (0.7 x 8 cm²) were treated by soaking with different chemicals [fungicides, a termiticide (chlorpyrifos or phoxim), a surface-active agent, a synergistic agent, and a stabilizer], and placed at right angles to each other on a fully grown mycelial mat of a test fungus in a Petri dish....

CEN Draft (38 N 460E) Standard: Test method for determining the protective effectiveness of a preservative in the marine environment
1986 - IRG/WP 4132
This European Standard describes a marine test method which provides a basis for asseasing the effectiveness of a wood preservative used to prevent attack of timber in sea-water by marine borers. The method is only suitable for testing preservatives which are intended to prevent attack by marine wood boring organisms of treated timber for use in more or less permanent contact with sea-water. It is...

Microcapsule formulation of fenitrothion as a soil termiticide
1991 - IRG/WP 1478
The efficacy and the mode of action of a microcapsule formulation of fenitrothion against Coptotermes formosanus Shiraki were investigated. The physicochemical property that this formulation does not allow the active ingredient to diffuse through the capsule wall contributed to a long lasting efficacy and safety for the men spraying. The residual effect of the fenitrothion microcapsule in soil was...

Effectiveness and synergistic effects between copper and polymer betaine
1996 - IRG/WP 96-30097
Different formulations of "Copper Amine" and Polymer Betaine were studied. During laboratory tests a synergism between both active ingredients against soft rot and dry rot has been found. The efficacy against soft rot according to the "BAM method" and the European Standard ENV 807 depends only on the amount of copper. Long term tests in a fungus cellar for determining the relative protective effec...
