Decomposition of metham sodium to methylisothiocyanate as affected by wood species, temperature, and moisture content

Creator:: Morrell, Jeffrey J.
Abstract:: The effect of various wood characteristics on decomposition of metham sodium to methylisothiocyanate in sixteen North American and Southeast Asian hardwoods and softwoods was investigated. While marked differences were noted in the degree of decomposition among some species, the relationship between decomposition and lignin content, extractive levels, wood pH, or...

Resistance of Selected Wood-Based Materials to Fungal and Termite Attack in Non–Soil Contact Exposures

Creator:: Morrell, Jeffrey J.
Abstract:: The resistance of three naturally durable heartwood species and a stranded giant bamboo product to fungal and termite (Coptotermes formosanus) attack was evaluated at a test site located near Hilo, Hawaii. Merbau (Intsia bijuga or I. palembanica) and ipe (Tabebuia spp.) were both exceptionally resistant to fungal and termite attack,...

Occurrence of preservative-treated wood in a wood recovery center in Western Oregon

Creator:: Morrell, Jeffrey J.
Abstract:: The amounts of treated wood present at a wood recycling center in western Oregon were surveyed over a 10-year period. Treated wood was found at 106 of 112 inspections, but the levels never exceeded 2 percent of the volume present. The amount of treated wood averaged 0.15 percent of the...

Durability of a changing western redcedar resource

Creator:: Freitag, Camille M. and Morrell, Jeffrey J.
Abstract:: The heartwood of western redcedar (Thuja plicuta) is known for its natural resistance to fungal attack, but some users of western redcedar utility poles have suggested that its durability may be diminished as suppliers begin to harvest trees from younger stands. The decay resistance of western redcedar samples from the...

Laboratory decay resistance of preservative-treated red alder

Creator:: Mitchoff, M. E. and Morrell, Jeffrey J.
Abstract:: Alder represents an abundant but underutilized resource that has little natural resistance to decay. Treated alder might be used for stakes, posts, or other nonstructural applications. The performance of alder treated with chromated copper arsenate (CCA), copper 8 quinolinolate, zinc naphthenate (ZN), or thiocyanomethylthiobenzothiazole (TCMTB) was assessed in soil block...

Fungal staining of ponderosa pine sapwood: Effects of wood preconditioning and bioprotectants

Creator:: Morrell, Jeffrey J. and Sexton, Camille M.
Abstract:: Differences in stain susceptibility were evaluated on sterile and unsterile samples of freshly sawn, frozen and thawed, or oven-dried and rewetted ponderosa pine sapwood. Samples treated with sterile medium or with medium inoculated with either Pseudomonas putida or Bacillus subtilis were inoculated with selected wood-staining fungi. In general, fresh unsterile...

Fungi colonizing redwood in cooling towers: Identities and effects on wood properties

Creator:: Morrell, Jeffrey J. and Smith, Susan M.
Abstract:: Heartwood from coastal redwood [Sequoia sempervirens (D. Don.) Endl.] is very durable and is often used untreated in harsh environments, such as cooling towers of power or chemical processing plants. Wood in this environment is often attacked by soft rot fungi. Some wood users attempt to bolster protection by including...

Fungal associates of Buprestis aurulenta in western Oregon

Creator:: Garcia, Carlos M. and Morrell, Jeffrey J.
Abstract:: Associations between the golden metallic beetle, Buprestis aurulenta L., and wood-destroying fungi were explored with adult beetles collected from log decks. A variety of fungi were isolated from the beetle bodies by four methods. A total of 863 isolations were made from 59 females and 21 males. There was no...

Conserving energy by environmentally acceptable practices in maintaining and procuring transmission poles for long service ; August 1988

Creator:: Morrell, Jeffrey J. and Corden, M. E. (Malcolm E.)
Abstract:: The eighth annual report details continued progress on each of the five objectives. In this year's report, Objectives II and III from previous reports have been combined to reflect the similarity of each effort. Improved fumigants: The previously established field trials continue to demonstrate the superior performance of both chioropicrin...
