  • Establishing a through-boring pattern and method of test for utility poles

    Creator:
    Elkins, Lori A.
    Abstract:
    The goal of this study was to optimize a through-boring pattern that will provide adequate preservative penetration while minimizing the reduction in overall pole bending strength. Hole spacing was developed using longitudinal and transverse chemical penetration data from previous studies. Finite element analysis was used as a preliminary assessment tool...

  • 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...

  • 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...

  • 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...

  • 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...

  • Fungal colonization of Douglas-fir sapwood

    Creator:
    Kang, Sung-Mo
    Abstract:
    The fungi that cause mold and stain of freshly sawn lumber result in millions of dollars in losses to the forest products industry. Stain and mold are typically prevented by either kiln drying or by application of a topical fungicide. While these treatments are effective, kiln drying is costly and...

  • 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...

  • Decomposition of Basamid in Douglas-fir heartwood

    Creator:
    Forsyth, Paul Griffin
    Abstract:
    Basamid^R (3,5-dimethy1-1,3,5,2H-tetrahydrothiadiazine- 2-thione) is a crystalline powder used as a soil sterilant. This fumigant acts in soil by decomposing to methylisothiocyanate (MITC), the primary active ingredient, as well as hydrogen sulfide, methylamine, and formaldehyde. In wood, Basamid decomposes too slowly to be efficacious against decay fungi unless amended with various...

  • 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...
