Laboratory evaluation of fipronil (a phenyl pyrazole) as a candidate termiticide in the protection of wood against the subterranean termite, Coptotermes acinaciformis (Froggatt) Rhinotermitidae
1997 - IRG/WP 97-10225
In this laboratory evaluation, radiata pine wood blocks (50 x 25 x 15 mm3) were impregnated with fipronil (a phenyl pyrazole) at various concentrations (0, 5, 10, 20, 40, 80, 100 and 200 ppm). Half the treated blocks underwent a leaching schedule for 5 days, while the remainder were unleached after treatment. Five replicates per treatment regime were presented to the test termite, Coptotermes acin...

Incorporation of phenyl boronic acid treatment with vapor phase formalization
1997 - IRG/WP 97-40083
Phenylboronic acid (PBA) treatment was incorporated with vapor phase formalization (VPF) in order to increase dimensional stability and boron fixation as well as enhancement of biological resistance. Five and ten hours VPF were applied after PBA treatment as 0.34, 0.50, 1.00 and 2.00% concs. aqueous solutions. Anti swelling efficiency (ASE) attended to 71% in specimens impregnated with 0.50% PBA s...

A field test with anti-stain chemicals on sawn pine timber in Brazil
1989 - IRG/WP 3513
Field tests were carried out in São Paulo State - Brazil, to evaluate pre-treatment formulations of O-Phenyl-Phenol (OPP) based products. The Sodium Pentachlorophenate solution was used as a reference formulation. The treated test blocks were stacked in a covered shed, and in an uncovered place for air drying. The evaluation was done by measuring the percentage of stained surface on each test blo...

Report on the efficacy and performance of the insecticide candidate termiticide in H2 field trials
2004 - IRG/WP 04-10516
This paper explains the field results of phenol pyrazole treated timber against in an above ground mound colonies of Coptotermes acinaciformis (Froggatt). C. acinaciformis (‘termites’) are the major pest of human structures throughout tropical and sub tropical regions, causing billions of dollars in damage to timber-in-service worldwide. The result of this field test have shown that candidate ...

Blue stain in timber in service. Progress review of Sub-group collaborative tests - 1981/82
1982 - IRG/WP 2178
Following from the discussions after reporting Document IRG/WP/2146 at the Meeting in Sarajevo, 1981, it was decided that 1.) more precise definition was needed of the artificial weathering schedules used in the work - participants to re-check Table 8 and send further details or amendments to Dr Bravery; 2.) a further test employing a wider range of chemicals was necessary using a smaller range of...
