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....

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...

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....

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...

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...
