A moisture containing wooden core substantially fully encapsulated within a formed in situ substantially non-wetting water impervious thermoplastic envelope. An effective amount of an insect and fungi controlling water soluble reagent is provided within the envelope. Preferably, there is sufficient moisture in the envelope so that the reagent will migrate substantially throughout the wooden core. The encapsulated workpiece is preferably formed by dipping or spraying the moist wood core with the aqueous reagent, and encapsulating the resultant treated core before it dries out so that the core remains moist throughout its expected life span. Green freshly harvested wood can be treated, coated, and used in direct competition with dried wood, without risk of its warping, splitting and checking during its expected useful life. Boron containing compounds are preferably used as the infection controlling reagents.
