Conserving energy by safe environmentally acceptable practices in maintaining and procuring transmission poles: third annual report ; June 1983

Creator:: Oregon State University and Oregon State University. Department of Forest Products
Abstract:: ABSTRACT Improved Fumigants After 13 years, chioropicrin, methylisothiocyanate (MIT), Vapam, and Vorlex continue to effectively control internal decay of pressure-treated Douglas-fir transmission poles. The estimated retreating schedules for application of these fumigants to treated wood may be as long as 10 years for Vapam and 15 years for the others....

Conserving energy by safe and environmentally acceptable practices in maintaining and procuring transmission poles: annual report ; August 1981

Creator:: Oregon State University and Oregon State University. Department of Forest Products
Abstract:: ABSTRACT Fumigants. Chioropicrin, Vapam and Vorlex continue to control Internal decay of Douglas-fir poles 11 years after application. Methylisothiocyanate (MIT), which was melted and poured into holes in Douglas-fir poles 3-years ago and goes directly from a solid to a gas in the wood, appears promising In controlling decay fungi....

Conserving energy by safe and environmentally acceptable practices in maintaining and procuring transmission poles for long service ; June 1982

Creator:: Oregon State University and Oregon State University. Department of Forest Products
Abstract:: ABSTRACT Improved Fumigants Chioropicrin, Vorlex and Vapam continue to control internal decay of pressure-treated Douglas-fir poles 12 years after application. Fungitoxic quantities of chloropicrin are present in the wood as high as 2.4 m (8 feet) above the groundline. Solid methylisothiocyanate (MIT), which goes directly to a vapor, is somewhat...

Conserving energy by safe and environmentally acceptable practices in maintaining and procuring transmission poles for long service ; August 1985

Creator:: Oregon State University and Oregon State University. Department of Forest Products
Abstract:: This fifth annual Cooperative Pole Research Program report outlines our progress in the six project objectives. Improved Fumigants Sampling of previously established field tests revealed that Vorlex and Chloropicrin continued to perform well after 15 years, while Vapam was slightly less effective. Solid methylisothiocyanate (MIT) also performed well in the...

Conserving energy by safe and environmentally acceptable practices in maintaining and procuring transmission poles ; August 1984

Creator:: Oregon State University. Department of Forest Products and Oregon State University
Abstract:: After 14 years, chloropicrin, Vapam and Vorlex continue to effectively control internal decay of pressure-treated Douglas-fir transmission poles, but 6 years after application of methylisothiocyanate (MIT) some poles are becoming reinfested by decay fungi although NIT residues remain high in these poles. The closed-tube bioassay, developed through our research, is...

Conserving energy by environmentally acceptable practices in maintaining and procuring transmission poles for long service ; September 1995

Creator:: Morrell, Jeffrey J., Corden, M. E. (Malcolm E.), and Oregon State University. Department of Forest Products
Abstract:: Previously established field trials of MTTC-Fume continue to show that this chemical remains in Douglas-fir and southern pine poles at fungitoxic levels 5 years after treatment. In general, increasing dosages resulted in higher chemical levels in the poles. All of the MITC-Fume treatments resulted in higher residual M1TC levels than...

Conserving energy by environmentally acceptable practices in maintaining and procuring transmission poles for long service ; October 1996

Creator:: Morrell, Jeffrey J., Corden, M. E. (Malcolm E.), and Oregon State University. Department of Forest Products
Abstract:: The Cooperative continues to actively address a diverse array of issues related to the effective use of wood utility poles. The trials to evaluate the effectiveness of MITC-Fume are now in their seventh year and continue to show that methylisothiocyanate (MITC) levels in MITC-Fume treatments remain higher than comparable metham...

Conserving energy by environmentally acceptable practices in maintaining and procuring transmission poles for long service ; August 1993

Creator:: Morrell, Jeffrey J., Corden, M. E. (Malcolm E.), and Oregon State University. Department of Forest Products
Abstract:: Evaluation of previously established field trials of internal remedial treatments continues to verify the excellent long-term protection afforded by these treatments. Field trials with gell encapsulated methylisothiocyanate (MITC) demonstrate that gelatin does not interfere with chemical release, nor is addition of supplemental moisture required for release. Field trials have been...

Conserving energy by environmentally acceptable practices in maintaining and procuring transmission poles for long service ; August 1992

Creator:: Morrell, Jeffrey J., Corden, M. E. (Malcolm E.), and Oregon State University. Department of Forest Products
Abstract:: Evaluation of previously established field trials of remedial internal treatments demonstrates the continued performance of chioropicrin, Vorlex, and methylisothiocyanate (MITC). While the degree of protection afforded by these treatments has declined with time, residual fungitoxic levels remain in many tests. Field trials of gelatin encapsulated MITC indicate that gelatin had...

Conserving energy by environmentally acceptable practices in maintaining and procuring transmission poles for long service ; August 1991

Creator:: Morrell, Jeffrey J., Corden, M. E. (Malcolm E.), and Oregon State University. Department of Forest Products
Abstract:: Evaluations of previously established field trials indicate that chioropicrin and Vorlex continue to provide a diminishing level of protection to Douglas-fir poles. Tests of solid methylisothiocyanate (MITC), now in their thirteenth year, indicate that this chemical continues to prevent recolonization of Douglas-fir poles by decay fungi. MITC appears to provide...
