Laboratory and field evaluation of Plasmite Reticulation System using bifenthrin as a chemical barrier within wall cavities against subterranean termites.
2005 - IRG/WP 05-20307
Laboratory and field bioassays undertaken to demonstrate Plasmite Reticulation system effectively delivers the termiticide (bifenthrin) within a simulated wall cavity at the required concentration. The chemical assay indicated that the amount of bifenthrin sampled at 5, 10, 15, 20, and 25m along the simulated reticulation system tested (30m) exceeded the manufacturer’s minimum recommendation of ...

Bifenthrin, a new insecticidal compound Bifenthrin has been extensively tested, to determine its potential use to control termites and other wood destroying insects. Bifenthrin is effective at extreme low rates which can minimize human and environmental exposure to the product. Results of tests carried out by several research institutes and by FMC in different countries will be presented. The phys...
Protection of OSB against termites by incorporation of different actives via glue line treatment
2008 - IRG/WP 08-30453
Different organic actives and zinc borate were incorporated into OSB during the manufacturing process to enhance the resistance against termites. Tests according to EN 117 revealed excellent performance of thiacloprid. Other organic actives such as permethrin might be effective when used in higher amounts. Zinc borate failed the test by far....

Permanence of permethrin and bifenthrin in framing timbers subjected to hazard class 3 exposure
2005 - IRG/WP 05-30383
End-sealed Pinus radiata specimens measuring 235 x 90 x 35 mm were treated using a modified Lowry schedule with permethrin or bifenthrin in white spirit to Hazard Class 2 (H2) retentions. After conditioning, the specimens were exposed at 45o on north facing racks near Melbourne (Australia). Samples of the specimens were taken before installation, and after three and six months exposure. Analyses o...

Efficacy of termiticide treatments to soil in field tests in the southern United States
1994 - IRG/WP 94-30043
In standard ground-board and concrete-slab efficacy tests in the southern United States, termiticides provide several years of subterranean termite control depending on rates applied to the soil and test site location. Years of 100% control (as of February 1994) provided by each currently marketed termiticide applied at highest label rates under concrete slabs in our four primary test sites (Flori...

Stability of bifenthrin in a commercial phenol-formaldehyde plywood glue
2003 - IRG/WP 03-30311
Liquid phenol formaldehyde (PF) glue mixes used for plywood manufacture are strongly alkaline. At this pH insecticidal additives may not be stable for long periods. In order to establish practical working life of the synthetic pyrethroid insecticide, bifenthrin, in liquid PF glues the concentration of bifenthrin in the glue mix was measured under laboratory conditions over a 24 hour period. Glu...

New research data confirming the suitability of bifenthrin as a wood preservative
1996 - IRG/WP 96-30116
Bifenthrin has been further tested against wood destroying insects, and its behaviour in wood has been extensively studied. Bifenthrin proved to be highly effective as a curative and preventative treatment against Anobium punctatum and Hylotrupes bajulus, after both leaching and evaporative ageing. Results of penetration tests with water and solvent based formulations, applied by brushing, dipping...

Bifenthrin recovery from glue-line-treated plywood
2007 - IRG/WP 07-20355
Plywood and laminated veneer lumber (LVL) can be protected from termite damage by addition of bifenthrin to the adhesive used in product manufacture. However, conditions associated with this manufacturing process may lead to deterioration or immobilisation of the active ingredient. In order to determine compliance with treatment specifications, it is important that the concentration of a preservat...

Preventing Xylosandrus crassiusculus Beetle Attack in Large Green Timbers Using Pyrethroid Dip Treatments
2008 - IRG/WP 08-10642
Although awareness about the risk of invasive species has increased over the past decade, a large number of highly destructive exotic pests are still being introduced around the world. One of the more important pest introductions in the Southeastern United States has been the Asian ambrosia beetle, Xylosandrus crassiusculus. This species is particularly important because of its ability to kill...

Effectiveness of a superficial treatment of bifenthrin to protect softwood framing from damage by subterranean and drywood termites in Indonesia
2009 - IRG/WP 09-40443
Various experimental testing procedures were undertaken in Indonesia to determine the effectiveness of a superficial (envelope) treatment of bifenthrin to protect softwood framing from damage by two species of subterranean termite (Macrotermes gilvus and Coptotermes curvignathus) and one species of drywood termite (Cryptotermes cynocephalus). Lengths of framing (Pinus radiata sapwood) were commerc...

Comparison of Bifenthrin Formulations for Their Skin and Eye Irritation Potential Using the Pollen Tube Growth Test
2010 - IRG/WP 10-30521
The Pollen Tube Growth Test (PTGT) is an effective screening method for measuring the potential of a chemical formulation to affect living cells. The PTGT has been compared against other types of testing, and it shows a good correlation with, for example, the Draize rabbit eye test and the human skin patch assay. It measures the EC50, which is the effective concentration at which 50% growth is o...

Evaluation of formulation type on the efficacy of bifenthrin as a glueline termiticide for veneer based wood products
2010 - IRG/WP 10-40486
Field trials were carried out in Australia on Coptotermes acinaciformis to evaluate the efficacy of various bifenthrin formulations. One trial tested plywood made by Zelam at their research facility in New Zealand and compared three emulsifiable concentrate formulations (EC), a suspension concentrate (SC) and an encapsulated formulation (CS). A second trial compared laminated veneer lumber (LVL)...

Investigating extraction of bifenthrin from composite wood products
2011 - IRG/WP 11-20467
Bifenthrin is added to resin prior to lay-up of plywood and laminated veneer lumber to provide termite protection. Analysis of this chemical in resins can be challenging. The potential for using ground wood in place of sawn material to recover bifenthrin was investigated using laminated veneer lumber composed of Douglas-fir veneers analyzed by three laboratories. Although the results differed amo...

NIR spectroscopy for rapid determination of permethrin or bifenthrin retention in P. radiata sapwood
2013 - IRG/WP 13-20507
Near infrared spectroscopy of permethrin or bifenthrin treated radiata pine (P. radiata D.Don) has been used to develop calibration models to later predict the active retention in unknown samples. Calibrations were developed for both a laboratory NIR and a portable NIR using laboratory-prepared calibration samples at a range of target retention levels. Correlations were established between the act...

A comparison of the resistance of pyrethroid-treated wood to damage by Coptotermes acinaciformis in Australia and C. formosanus in China and the USA
2014 - IRG/WP 14-10830
Field trials, using a single aboveground method of exposure, were used to assess a range of retentions of two pyrethroids (bifenthrin and permethrin) in Pinus radiata D. Don sapwood against two species of Coptotermes in three countries to provide directly comparable results. Coptotermes acinaciformis (Froggatt) in Australia, C. formosanus Shiraki in China and C. formosanus in the USA consumed simi...

Analytical retentions of active ingredients in H2F treated framing over a 12-year period
2023 - IRG/WP 23-20702
The H2F hazard class in Australia was developed to treat internal framing timber with a surface application of an insecticide, to control mainly termites. Two of the actives approved in AS 1604.1-2010 (and subsequent revisions) for this hazard class are bifenthrin and imidacloprid. The penetration zone of both actives is 0 – 2 mm from the wood surface. Radiata pine sapwood framing timber wa...
