Characterization of Fungal Communities in Selected Wood Species by Field Exposure Tests

Creator:: Torres-Andrade, Paola A.
Abstract:: Fungi are the primary biological agents of wood deterioration and cause major economic losses of wood products globally. Wood in outdoor applications tends to remain wet for extended time periods, making it susceptible to fungal attack. Understanding the factors involved in fungal colonization of wood is important for developing improved...

The Effect of Sill Height on Decay in Air-Seasoning Crossties

Creator:: Rogers, Leon R.
Abstract:: The sustainable use of wood for rail ties requires chemical treatment to increase service life and maintain structural integrity. Treatment can only be applied after lengthy air-seasoning to reduce moisture content in wood, but seasoning leaves ties exposed to attack by decay fungi for up to a year. One factor...

Potential for Using Boron Compounds with Differing Water Solubilities in Pastes for Remedial Treatment of Utility Poles

Creator:: Uysal, Selim
Abstract:: Boron and boron compounds have been long used for pressure treatment, dip-diffusion, and remedial treatments of wood because of their proven efficacy against fungi and insects. These materials are especially attractive because their high water solubility promotes deeper penetration into wood. Other useful properties of boron include its neutral pH,...

Development of a test method for assessing water repellency and derived physical stability of preservative systems for railroad ties

Creator:: Beck, H. Greeley
Abstract:: Resistance to moisture uptake is an important attribute of some wood preservatives and can help reduce moisture cycling that leads to the development of deep checks. While the potential for preservative treatments to help improve wood/moisture interactions is acknowledged, there are no tests that specifically evaluate this performance parameter. Checking...

Effects of best management practices on copper migration from Douglas-fir lumber treated with ACZA, CA or ACQ

Creator:: Ye, Min
Abstract:: Copper is the most common ingredient in waterborne preservatives and provides excellent activity against most fungi and insects. However, issues associated with copper migration from treated wood have created increasing concerns about potential risks to non-target organisms in surrounding environments, especially those in sensitive aquatic environments. Various Best Management Practices...

Management of powder-post beetles, Dinoderus minutus F. in freshly cut bamboo

Creator:: Garcia, Carlos Manalo
Abstract:: The goal of this project was to develop an integrated pest management strategy for the control of a powder-post beetle (Dinoderus minutus F.). This species causes serious damage in Philippine bamboo. Developmental threshold and thermal constants were examined and natural enemies and ftmgi associated with beetles were investigated. Finally, the...

Supercritical fluid impregnation with biocides of wood using temperature reduction

Creator:: Kang, Sung-Mo
Abstract:: Supercritical fluid (SCF) impregnation is a promising preservative treatment method, however, the development of SCF processes has been slowed by a limited understanding of the process. Developing a better understanding of the effects of various process parameters on treatment results would allow for a more rational development of SCF impregnation....

Performance of copper based biocides in potentially copper tolerant soils

Creator:: Chang, Andrew B.
Abstract:: Copper is an excellent biocide which has a long history of usage for protecting wood from deterioration, but some organisms have developed tolerance for this chemical. Copper tolerance among wood decay fungi is a poorly understood phenomenon that is gaining importance as cofactors such as arsenic and chromium are removed...

Modeling changes in flexural properties of softwood beams during fungal decomposition

Creator:: Mitsuhashi Gonzalez, June M.
Abstract:: Moisture intrusion in residential structures can lead to substantial fungal decay and this damage costs billions in repair/replacement costs. The extent of damage and the rate at which it occurs are primarily dependent on the wood moisture content and temperature in the structure. Determining the risk of decay for various...

Application of green fluorescent protein (GFP) for studing interactions between Ophiostoma piceae and Trichoderma harzianum in freshly sawn Douglas-fir sapwood

Creator:: Xiao, Ying
Abstract:: While microbial colonization of wood is presumed to be characterized by a myriad of interactions between numerous organisms, studying these processes is often difficult owing to the opaque nature of the wood and the inability to readily distinguish among the many species colonizing the material. One method for enhancing the...
