Performance of 3-iodo-2-propynyl butyl carbamate (IPBC) in L-joints under tropical conditions
IRG/WP 16-30688
J J Morrell
The ability of 3-iodo-2-propynyl butyl carbamate (IPBC) to protect wood against fungal decay out of soil contact was evaluated using ponderosa pine L-joints at two exposure sites over a 12 year period. IPBC tended to provide better protection when formulated in an organic solvent and when applied using a double vacuum treatment. Performance also tended to be better when systems contained a water repellent. As expected, fungal damage occurred markedly more rapidly in the tropical site, but similar trends were beginning to be observed at the more temperate site.
