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...

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...

Bioprotection of unseasoned Ponderosa pine lumber from microbial discoloration

Creator:: Kreber, Bernhard
Abstract:: The potential of 9 bacterial and 6 fungal isolates to protect wood against wood staining microorganisms was studied using small sapwood samples of unseasoned Ponderosa pine [Pinus ponderosa Laws] sapwood. Bacillus subtilis Cohn, isolate 733 A , Gliocladium virens J.H. Miller, J.E. Giddens & A.A. Foster isolate H 3 and...

The role of lytic enzymes in biocontrol of sapstain fungi

Creator:: Liu, Jiajian
Abstract:: The biocontrol potential of Trichoderma harzianum strains B-2A, B-8A, B-4B, B-15B, and B-41 and Serratia plymuthica was evaluated using agar plates and wood wafers of unseasoned ponderosa pine (Pinus ponderosa laws). All five isolates of Trichoderma harzianum and Serratia plymuthica could inhibit stain fungi growth in agar plates and exhibited...

Biology of the carpenter ants Camponotus vicinus (Mayr) and Camponotus modoc (Wheeler) in western Oregon

Creator:: Mankowski, Mark E.
Abstract:: Pest control operators in Oregon were surveyed to examine the occurrence of carpenter ants and other wood destroying organisms in structures. Carpenter ants frequently occurred in the coast and Willamette valley regions of the state and were associated with wetter, mesic habitats. To examine the effects of substrate and moisture...

Utilization of ground peanut husk as an alternative fiber material for particleboard

Creator:: Newton, Jacob A.
Abstract:: This research examined the potential for using peanut husk as a fiber alternative to wood in the production of melamine-formaldehyde (MF) particleboard. MF resin was used to produce panels with one, three, six, nine or 12 percent resin contents. Modulus of Rupture (MOR), Modulus of Elasticity (MOE), Internal Bond (IB)...

Controlling biodeterioration of western wood species with over- the-counter wood preservatives

Creator:: Newbill, Mark A.
Abstract:: Over-the-counter (OTC) wood preservatives can provide wood with both a moisture barrier and fungicidal protection against biodeterioration, yet there is little comparative data on the performance of these preservatives. In this study, the potential of various low-toxicity, OTC preservatives was evaluated on five western wood species, western red cedar (Thuja...

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...

The effects of tree position and silvicultural practices on treatability of Douglas-fir lumber

Creator:: Hong, Seungdo
Abstract:: In spite of the lack of accurate information about the treatability of western wood species with waterborne wood preservatives, consumption of these products continues to increase. Western wood species, notably Douglas-fir, are notoriously difficult to treat with waterborne systems, yet there is relatively little data on the effects of wood...

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,...
