Abstract:: This seventh annual report outlines our continued progress on each of six objectives. Improved fumigants: We continue to evaluate previously established field tests, which inlicate that chioropicrin continues to protect Douglas-fir poles after 17 years and piling after 12 years. Vorlex treated poles are being gradually recolonized by decay fungi,...

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...

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:: A small-scale test was developed to evaluate the ability of fungicides to control decay fungi established in wood. The test, which uses blocks 2.5 x 2.5 x 10 cm, tests the ability of a chemical to migrate from the middle of the block to control a previously established decay fungus,...

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....

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....

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...
