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)...

Comparison of rates of wood decay from four different field test protocols following 4-5 years exposure at a site in New Zealand
2011 - IRG/WP 11-30565
The rate of decay of Pinus radiata was evaluated using four different field test protocols at a site near New Plymouth, New Zealand. The average Scheffer index was 86 over the five year period of testing. The field tests were an in-ground stake test (AWPA Std E7-01) and three above ground tests – lap-joint (AWPA Std E16-98), decking (AWPC protocol) and ground proximity tests (AWPA Std E18-06) T...

Termite resistance of timber envelope treated with imidacloprid then modified by typical building site operations
2011 - IRG/WP 11-30570
Imidacloprid is a new envelope insecticide approved by Australian regulatory authorities for framing timber. It is a non repellent insecticide. Results are reported for timber envelope treated with imidacloprid and altered post treatment with typical building site operations to expose untreated surfaces. These modifications included, cutting, notching and drilling. Pinus radiata timber samples w...

Thiacloprid as a glueline termiticide for veneer based wood products
2012 - IRG/WP 12-30592
Thiacloprid is an insecticide commonly used in the agricultural industry. No evidence of its commercial use in wood has been discovered by the authors. Results are reported for veneer based wood products treated with thiacloprid via the glueline. Thiacloprid was tested against Coptotermes acinaciformis following the brick assembly technique as described in the Australasian Wood Preservation Com...

Glueline fungicides in veneer based engineered wood products - results from laboratory work for the H1.2 hazard class in New Zealand
2012 - IRG/WP 12-30593
The use of glueline insecticides in plywood and laminated veneer lumber is commonplace in several countries. However, few glueline fungicides are registered for commercial use with previous work suggesting that achieving control of decay from the glueline is very challenging. This paper summarises two tests completed on Pinus radiata plywood with a new glueline fungicide comprising the active in...

Methylene Chloride compared with white spirit as a treatment solvent for wood preservation – results from decay and termite studies
2013 - IRG/WP 13-30611
Non-aqueous solvents have a long history in the treatment of wood products in various parts of the world. The most familiar solvent treatment is the ‘light organic solvent preservative’ (LOSP) treatment based on low density solvents such as white sprit. Until recently white spirit was the only non-aqueous solvent approved for use in wood preservation in New Zealand. Australia also permitted...

Comparison of untreated plywood and untreated LVL in a field trial against Coptotermes acinaciformis and in laboratory trials against Tyromyces palustris and Coniophora puteana
2014 - IRG/WP 14-40671
In Australasia, efficacy data obtained on plywood is generally acceptable for laminated veneer lumber (LVL) and vice versa. This is particularly the case with glueline treatment approvals. The rationale is that the two wood products have predominately the same basic structure with the key difference being orientation of the veneer. LVL typically has all veneers in parallel while plywood typical...
