In-ground performance of two formulations of chlorothalonil after five years of exposure at three test sites in Australia
1996 - IRG/WP 96-30101
Sapwood specimens of Pinus radiata D. Don and Eucalyptus regnans F. Muell. were each treated to three retentions of each of two preservative formulations (chlorothalonil in oil; chlorothalonil plus chlorpyrifos in oil) and installed in-ground at three field test sites in Australia. Specimens were treated with each formulation to achieve 3.2, 6.4 and 12.8 kg/m³ of chlorothalonil a.i. and 3.2 + 0.2...

In-ground evaluation of a copper azole wood preservative (Tanalithâ E) at a tropical Australian test site
1996 - IRG/WP 96-30100
A field trial to determine the in-ground termite and decay resistance of Pinus radiata D. Don impregnated with a copper azole formulation, TANALITHâ E, has been established at a tropical site in the Northern Territory of Australia. Four retentions of TANALITHâ E, containing 1.54, 2.08, 2.92 and 4.30 kg/m³ of Cu, are being evaluated. For comparison, Pinus radiata specimens treated to two retenti...

Laboratory bioassay on the termiticidal efficacy of two ACQ formulations
1999 - IRG/WP 99-30199
The termiticidal efficacy of two ammoniacal copper quaternary ammonium formulations (ACQ) was evaluated in a laboratory bioassay using two species of subterranean termites, Mastotermes darwiniensis Froggatt and Coptotermes acinaciformis (Froggatt). Five retentions (1.0, 2.0, 4.0, 6.0 and 8.0 kg/m3 of active ingredient) of each ACQ formulation (MitrexACQ and ACQ97) were assessed in sapwood specimen...

A laboratory bioassay on the termiticidal efficacy of a chlorothalonil formulation and a chlorothalonil plus chlorpyrifos formulation to Mastotermes darwiniensis Frogatt
1993 - IRG/WP 93-30004
Results of a laboratory bioassay on the efficacy of two preservative formulations (chlorothalonil in oil; chlorothalonil plus chlorpyrifos in oil) to the Australian subterranean termite Mastotermes darwiniensis Froggatt are given. Specimens of Pinus radiata D. Don sapwood were treated to three retentions of each formulation to achieve 3.2, 6.4 and 12.8 kg/m³ of chlorothalonil a.i. and 3.2 + 0.2, ...

Wood preservation using furanones derived from marine algae
2004 - IRG/WP 04-10506
Halogenated furanones that are analogues of natural compounds extracted from the red seaweed Delisea pulchra were examined in the laboratory for activity against termites and decay fungi. The furanones were found to have broad spectrum activity, some with solution strengths of 0.01% controlling Coptotermes acinaciformis in a filter paper trial, while 2% solutions impregnated into Pinus radiata blo...

An evaluation of the efficacy of a chlorothalonil formulation and a chlorothalonil plus chlorpyrifos formulation in the field
1993 - IRG/WP 93-30005
Details on the treatment of Pinus radiata D. Don and Eucalyptus regnans F. Muell. sapwood specimens to three retentions of each of two preservative formulations (chlorothalonil in oil; chlorothalonil plus chlorpyrifos in oil) and their installation below ground at three field test sites in Australia are given. Specimens were treated with each formulation to achieve 3.2, 6.4 and 12.8 kg/m³ of chlo...

Laboratory evaluation of the termiticidal effectiveness of TanalithÒ 3485
1995 - IRG/WP 95-10109
The termiticidal effectiveness of the copper azole TANALITH 3485 was evaluated with the benchmark preservative TANALITH C in a laboratory bioassay using two species of subterranean termites, Mastotermes darwiniensis Froggatt and Coptotermes acinaciformis (Froggatt). Retentions of TANALITH 3485 tested were 0.15, 0.24, 0.285 and 0.40% m/m Cu and for TANALITH C 0.025, 0.05, 0.08 and 0.095% m/m Cu. Un...

Comparison of the in-ground performance of pigment emulsified creosote (PEC) and high temperature creosote (HTC)
2000 - IRG/WP 00-30217
A long-term field trial was conducted in Australia to compare the in-ground performance of two oil-borne preservative formulations, conventional high temperature creosote (HTC) and a modified creosote formulation, pigment emulsified creosote (PEC). Three retentions (50, 100 and 200 kg/m³) were targeted for each formulation. An additional retention of PEC formulation (308 kg/m³), which contained ...

Lyctine susceptibility testing and dealing with rarely susceptible hardwood species
2007 - IRG/WP 07-10607
This study examined the lyctine susceptibility of 16 timber species or hybrids. Several of the timbers have been placed previously in a ‘rarely susceptible’ category, but for standards and compliance purposes, such in-between ratings are not acceptable. Timber specimens were spot tested for starch content, and exposed to three species of lyctine beetles in an insectary. New criteria were devel...
