The Effect of Soil on the pH of Untreated Southern Pine in Ground Contact
2010 - IRG/WP 10-10742
Untreated southern yellow pine samples were subjected to three soils that had been amended to provide acidic, neutral and alkaline conditions. Wood pH was measured prior to, and then one, two, four and eight weeks after being placed in the soil to determine the effect of soil pH on wood pH....

The Effect of Soil pH on the pH of Treated Southern Pine in Ground Contact after 12 Months
2011 - IRG/WP 11-50281
Southern pine samples treated with soluble and particulate copper solutions were subjected to three soils that had been amended to provide acidic, neutral and alkaline conditions. Wood pH was measured prior to, and after 6 and 12 months after being placed in the soil to determine the effect of soil pH on wood pH....

Preventing the introduction of Xylosandrus crassiusculus by dipping green lumber in insecticides prior to shipment
2007 - IRG/WP 07-40370
Xylosandrus crassiusculus, an ambrosia beetle native to Asia and Africa, was introduced into the southeastern United States in 1974. Since that time, this species has substantially expanded its range, causing damage to native ecosystems and healthy nursery stock. This species was found in The Dalles, Oregon in 2004, indicating that it is not limited to sub-tropical environments. This introducti...

Preventing Xylosandrus crassiusculus Beetle Attack in Large Green Timbers Using Pyrethroid Dip Treatments
2008 - IRG/WP 08-10642
Although awareness about the risk of invasive species has increased over the past decade, a large number of highly destructive exotic pests are still being introduced around the world. One of the more important pest introductions in the Southeastern United States has been the Asian ambrosia beetle, Xylosandrus crassiusculus. This species is particularly important
because of its ability to kill...

The Relative Performance of an Organic Preservative System under UC3A and UC3B Conditions using Two Test Methods
2010 - IRG/WP 10-20429
Coated L-joints have been used for decades to evaluate the performance of wood preservatives in protected environments. This study was conducted using matched coated and uncoated L-joints to simulate above ground protected and unprotect exposures. When exposed to constant moisture in a greenhouse environment, coated and uncoated L-joints give very similar performance results. In contrast, exposi...

Above ground testing at tropical test sites, what have we learned?
2011 - IRG/WP 11-20473
Three different above ground test methods have been utilized at a selection of five tropical and sub-tropical test sites with a variety of treated and untreated material. The results show that a multi-site approach to above ground field tests presents the opportunity for exposure to un-predicted biodeterioration hazards, which may be important for developmental products of poorly characterized fu...

Phytosanitary standards and the potential for acceptance of chemical treatments as a phytosanitary measure
2011 - IRG/WP 11-30558
Regulations governing international trade in forest products must balance the economic and social benefits of trade with the potential risks of transporting invasive species. The International Plant Protection Convention (IPPC) is an international agreement intended to manage this process. It develops international phytosanitary standards (ISPMs) that are recognised by the World Trade Organisation...

Using an accelerated laboratory method to evaluate Aureobasidium pullulans colonization on painted surfaces and underlying wood substrate
2012 - IRG/WP 12-20480
Mold growth on painted surfaces can lead to premature paint film failure and is unsightly. Aureobasidium pullulans has been identified as a major cause of black stain on surfaces painted with acrylic or latex paints. In this study, an accelerated laboratory method developed by Zabel and Horner (1981) was used with modifications to the type of agar used and sample evaluation methods. A study was ...
