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:: 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:: 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....
