IN LARGE TIMBERS FUMIGANTS STOP ROT THAT GOOD DESIGN COULD HAVE PREVENTED

Failure to shelter wood from weather, to avoid joints that trap water, or to use preservative-treated wood--all preventable by good design--continue to create conditions favoring decay, which impairs the serviceability of wood structures. Seasoning checks that trap water are the most serious, and probably least understood, threat to the performance of timbers. Internal rot can be stopped by placing volatile chemicals in holes that are drilled in the timbers and plugged. The gases diffuse throughout the wood, eliminating decay fungi and insects for about 2.5 m from the treating site. Vapors of some chemicals were present 8 years after application so retreating cycles are expected to exceed 10 years.
