Protection of Ochroma pyramidale from fungal decay with N,N-napthaloylhyroxylamine
1998 - IRG/WP 98-30182
Fungal decay of wood in service results in billions of dollars (U.S.) in losses annually. Recent environmental restrictions, both U.S. and international, are limiting and eliminating the use of broad-spectrum, heavy metal biocides for wood preservation. Restrictions result primarily from problems with disposal. New wood preservatives need to be developed and tested which specifically target key el...

Restriction for use and waste management for pressure treated wood - The current situation in Norway
2001 - IRG/WP 01-50175
The Norwegian Environmental Authorities have this winter sent out a draft on restrictions in production and use of heavy metals in preservative treated timber. If it is passed, it will lead to drastic changes in the use of preservatives in Norway from this autumn. The environmental authorities and the preservative industry are both at present discussing waste management for CCA and creosote treate...

Detection of the dry rot fungus Serpula lacrymans by amplified ribosomal DNA restriction analysis
1998 - IRG/WP 98-10245
Isolates of the dry rot fungus Serpula lacrymans and the wild merulius S. himantioides were investigated by amplified ribosomal DNA restriction analyses (ARDRA) of the internal transcribed spacers (ITS). The technique uses the polymerase chain reaction (PCR) to amplify the variable region of the ITS between the conserved 18S and 28S genes of the nuclear ribosomal DNA (rDNA).
The ITS region of all isolates of Serpula lacrymans and S. himantioides was successfully amplified. The length of the amplified product was about 630 bp. Subsequent double digest of the ITS with the restriction endonucleases Haelli and Taql separated the closely related fungi by species-specific fragments. Thus, ARDRA-ITS proved to be suited for the detection of the dry rot fungus.

Effects of chlorothalonil (CTN) and butylated hydroxytoluene (BHT) on microbial communities involved in the deterioration of wood using T-RFLP II: Results from field studies
2007 - IRG/WP 07-30429
The effects of Chlorothalonil (CTN) and Butylated Hydroxytoluene (BHT) on microbial species diversity in wood and the surrounding soil are being assessed by Terminal Restriction Fragment Length Polymorphism (T-RFLP). CTN was selected as a trial organic wood preservative, and the non-biocidal BHT was evaluated for its synergistic effects with CTN. ACQ-C was a positive control and untreated SYP sta...

Microbial Community Analysis Using Terminal Restriction Fragment Length Polymorphism (T-RFLP) Analysis: Field Study Results
2008 - IRG/WP 08-20377
The effects of chlorothalonil (CTN) and butylated hydroxytoluene (BHT) on the fungal community in southern yellow pine (SYP) were assessed using terminal restriction fragment length polymorphism (T-RFLP) analysis. Field stakes treated with 0.25% and 0.37% ammoniacal copper quat (ACQ-C), 0.1 and 0.25% CTN, and 0.1 and 0.25% CTN combined with 2% BHT were installed with untreated controls in field s...

Bacterial Degradation of Pentachlorophenol Indicated in Groundwater Undergoing Long Term In-Situ Remediation
2016 - IRG/WP 16-50318
Pentachlorophenol (PCP, Penta) is a worldwide soil and water contaminant. The pervasive use of PCP as a fungicide, herbicide, pesticide, and as preservative for wood products has led to its global distribution. It is a highly effective preventative measure for most invasive insects, bacteria, fungi, and molds, as well as an excellent wood protection treatment. This study examined a known PCP conta...
