An Open Letter to Proponents of CLT/Massive Timber
2016 - IRG/WP 16-40755
We present an Open Letter that discusses the need to address the potential for biodeterioration in CLT/Massive timber structure. We invite members to review and sign the document. We also welcome suggestions for potential recipients....

Is there a role for termite alates in colony expansion in Wisconsin?
2014 - IRG/WP 14-10820
Termite colonies in Wisconsin tend to be large and widely spread out geographically, and separated by distances up to 1342km. We recently completed a study to determine the genetic diversity and population substructure of thirteen existing colonies of Reticulitermes flavipes using amplified fragment length polymorphism to determine patterns of termite dispersal in Wisconsin. Measures of inbreedin...

Termiticide Residues in Gravel Fill
2014 - IRG/WP 14-20553
Downward dispersion of liquid termiticide in gravel was determined by measuring active ingredient (a.i.) residues of two frequently applied liquid pyrethroid termiticides during one year following surface applications at lowest label rates (Up-Cyde Pro® 2 EC-cypermethrin; BaseLine® EC-bifenthrin) over the two most extensively used commercial building construction gravel foundation fills in Oklah...

Termiticide Residues in Building Foundation Aggregate Fills After Trench and Surface Applications
2015 - IRG/WP 15-30679
Termiticide concentrations (ppm) in aggregate fill were determined by measuring active ingredient (a.i.) residues of two pyrethroid termiticides, Up-Cyde Pro® 2EC-cypermethrin, and BaseLine® EC-bifenthrin, at 24.0 hours, and then at 6.0- and 12.0-months after ‘horizontal’ surface applications, perimeter ‘trenching and rodding’ applications, or ‘rodding only’ trench applications at lo...

Post-layup protection of mass timber elements in above ground protected exposures: 2-year results
2022 - IRG/WP 22-30766
Mass timber has seen increased use as a building material for low and mid-rise construction in recent decades. The durability of mass timber elements has not been fully examined and the effects of wood destroying organisms on this these materials merits attention. The effectiveness of currently labeled soil termiticides and passively applied biocides at post-construction or as remedial agents need...
