Preventing fungal attack of freshly sawn lumber using cinnamon extracts
2007 - IRG/WP 07-30432
The potential for using cinnamon oil as an anti-mold and stain compound was investigated on ponderosa pine sapwood. Cinnamon oil was highly effective when used in ethanol, but its activity declined when it was mixed with only water. Attempts to enhance water solubility with surfactants improved solution stability, but had no apparent effect on biological activity. Further studies with other co-so...

An evaluation of chemical treatments for the protection of radiata pine logs from fungal degrade
1986 - IRG/WP 3377
Busan 30, Busan 1009, Mitrol PQ375. and sodium pentachlorophenoxide (NaPCP) plus have been evaluated as antisapstain treatments for the long-term protection of debarked radiata pine logs. After 3 months' winter-spring storage, treated debarked logs had less surface and internal sapstain than 'control' logs. After 6 months' storage all logs had internal sapstain ...

A chemical and mycological evaluation of fused borate rods and a borate/glycol solution for remedial treatment of window joinery
1983 - IRG/WP 3225
The possibility of using fused borate rods (Impel Borpatron) and a borate/glycol solution (Boracol-40) for depot impregnation of window joinery has been examined in a co-operative project between The Swedish Forest Products Research Laboratory, The Swedish University of Agricultural Sciences and Prolignum AB. The fused Impel rod is a glassy rod composed of disodium octaborate which readily dissolv...

Durability of Bamboos in India against termites and fungi and chemical treatments for its enhancement
2005 - IRG/WP 05-10553
Bamboo is a very important forest resource that benefits the life of people in a myriad ways including meeting the need for structural uses like posts, pole fencing, scaffoldings, house building, etc. Although it is one of the strongest structural material available, often succumbs to fungal decay and biodeterioration by insects (termites and powder post beetles) during storage and usage. Studies...

Remedial ground-line treatment of CCA poles in service. Results of chemical and microbiological analyses 6 months after treatment
1986 - IRG/WP 3388
CCA-treated poles in service with incipient internal soft rot were remedially treated by inserting borate rods, brushing with a boron/glycol solution and injecting boric acid paste, copper/creosote paste or a commercial product (DFCK paste). The spread of active chemicals in the treated zone as well as the change in microflora have been studied with time. After six months chemicals had spread to m...

Preservative treatment and field test monitoring of spruce pole stock: Pressure and diffusible chemical treatments
1990 - IRG/WP 3605
One hundred and forty four spruce (test species) and southern yellow pine (reference species) poles were variously treated by center boring, incising, or kerfing, followed by pressure treatment with CCA and/or diffusible preservatives. The diffusible preservatives included NaF/creosote, borax and ammonium bifluoride. The poles were set at a test site and evaluated for preservative distribution and...

An evaluation of chemical pre-treatments for controlling kiln brown stain in radiata pine
1997 - IRG/WP 97-30124
Clear radiata pine (Pinus radiata D. Don) is widely used for fine millwork owing to its attractive light colour. However, kiln drying of radiata pine sapwood often results in the development of a brown stain causing substantial loss in revenues in New Zealand's high-value export markets. In this study chemical pre-treatments were evaluated for their ability to control the formation of kil...

Controlled envelope treatments of Pinus sapwood, achieved by modifications to impregnation process and carrier solvents
2003 - IRG/WP 03-40258
Specimens of slash pine or radiata pine were treated to a target retention of 0.02% m/m permethrin with conventional light organic solvent fluids or with oil-modified fluids (Tanalith® T). Best achievable envelopes from LOSP fluids were poorly controlled, penetrating not only the target outer 0-5 mm zone (mean 0.019%, RSD 28%), but also breaking through into the 5-10 mm zone (mean 0.013%, RSD 37%...

Prevention of non-microbial sapwood discolorations in hardwood lumber: chemical and mechanical treatments
1997 - IRG/WP 97-30137
Sapwood discolorations in hardwood lumber that are non-microbial in origin result from the formation of pigmented starch-like granules in ray parenchyma cells. These discolorations can be prevented by treating unseasoned lumber with an antioxidant (sodium bisulfite). Exposing unseasoned lumber to microwaves or treating logs with fumigants also will prevent these discolorations. Subjecting unseason...

A 53-year old field trial to evaluate the performance of a range of chemical treatments on eucalypt poles
1989 - IRG/WP 3526
Hardwood pole stubs of Eucalyptus maculata, Eucalyptus pilularis, Eucalyptus saligna and Eucalyptus paniculata were examined for termite attack and fungal decay after 53 years in ground contact. The trial compared eight different chemical treatments with untreated pole stubs of the four species investigated. Untreated Eucalyptus paniculata, a Class I durability species, performed particularly well...

Phytosanitary standards and the potential for acceptance of chemical treatments as a phytosanitary measure
2011 - IRG/WP 11-30558
Regulations governing international trade in forest products must balance the economic and social benefits of trade with the potential risks of transporting invasive species. The International Plant Protection Convention (IPPC) is an international agreement intended to manage this process. It develops international phytosanitary standards (ISPMs) that are recognised by the World Trade Organisation...

Biocontrol of wood decay insects and nematodes as an alternative to traditional chemical treatments
2018 - IRG/WP 18-10914
The protection of wood has been defined until relatively recently, as the application of a chemical to increase its durability. On the other hand, society is becoming more and more demanding in terms of the use of products which have the minimum ecological impact. This has led many countries to reduce the list of biocidal products that can be used (European Biocides Regulation), therefore it is ne...

Development of beech wood thermo-chemical modification treatments based on different vinylic derivatives of glycerol and polyglycerol
2019 - IRG/WP 19-40855
In this study, a combination between chemical and thermal wood modification has been investigated. Seven types of a low concentration of 10% aqueous additive solution of vinylicglycerol [glycerol-maleic anhydride (Gly-MA), glycidyl methacrylate (GM), and Glycerol methacrylate-maleic anhydride (GM/MA(2eq))], vinylicpolyglycerol [polyglycerol-maleic anhydride (PG-MA), polyglycerol methacrylate (PGM...

Biological screening assays of wood samples treated with creosote plus chemical additives exposed to Limnoria tripunctata
1980 - IRG/WP 408
Laboratory methods for exposure of treated wood coupons to Limnoria tripunctata are described. Chemical additions to creosote were screened using this method. Three pesticides, Endrin, Kepone, and Malathion proved particularly effective. The addition of varying percentages of naphthalene to creosote using several treatment methods are currently being assayed. Results to date show that the coupons ...

Proposed method for out-of-ground contact trials of exterior joinery protection systems
1981 - IRG/WP 2157
Methods for testing the efficacy of preservative treatments for exterior joinery are described using the format of a European Standard. Commercially used treatments applied to jointed test units (L-joints) which are then protected by conventional finishes are exposed to normal outdoor hazards out of ground contact. Assessment is made a) by determining eventual failure through decay and b) by destr...

Comparative response of Reticulitermes flavipes and Coptotermes formosanus to borate soil treatments
1991 - IRG/WP 1486
Eastern (Reticulitermes flavipes [Kollarl]) and Formosan (Coptotermes formosanus Shiraki) subterranean termite workers (Isoptera: Rhinotermitidae) were exposed to borate-treated sand in an indirect exposure tunneling assay in the laboratory. In the ten day assay period, both termite species readily penetrated sand containing 5000, 10000, or 15000 ppm (wt. of compound / wt. of sand) disodium octabo...
