Non Technical Summary
PhotoAn important limitation to the usefulness of wood, and a prime cause of user dissatisfaction, is its vulnerability to biodeteriorating fungi and insects under certain conditions of storage and use. Efforts to protect wood from biological degradation have successfully reduced the demand for lumber from our National Forests by reducing the need to repeatedly replace existing wood products. Targeted protection systems are needed to replace the broad spectrum biocides traditionally used to inhibit decay and mold fungi, and termites. Mold growth and its impact on indoor air quality have become an increasingly problematic housing issue despite the fact that mold fungi do not cause structural changes to wood. Airborne spores can cause health problems in human occupants and their presence is indicative of elevated moisture. Environmentally benign mold inhibitors for surface treatment of dimension lumber or for incorporation into engineered composites need to be developed.

Objectives Summary
New environmentally compatible preservatives will be developed to replace conventional broad-spectrum pesticides. We will develop, test and validate new evaluation methods based on biochemical properties of decay fungi or mechanical properties of wood. Experimental formulations assessed in laboratory mold, decay and termite tests will be correlated with field tests.

Approach Summary
Results from studies that reveal the fungal mechanism of preservative tolerance and the termite mechanism of maintaining colony vitality will be used to develop targeted inhibitors that will replace broad spectrum chemical biocides. We will develop a genetic database of microbial activity during the process of wood deterioration that will elucidate the microbial ecology of in vivo biodeterioration in the context of our changing climate. Novel protection methods will incorporate nanotechnology for design and/or controlled delivery of biocides for improved durability of building materials, with an emphasis on engineered composites. Outcomes from foundation research will be used to address protection of wood products from fungal and insect attack in interior applications as well, where air quality and occupant safety are important.
