Fungicidal combination products
1987 - IRG/WP 3426
Due to the increased pressure on some of the established fungicides used in wood preservation, possible alternative products become more interesting. The requirements for new chemicals are mainly lower toxicity and greater environmental acceptability. However the efficacy to target organisms should be as good as that of the currently used ones, preferably better. A possibility for progress in this...

Oxygen index levels and thermal analysis of wood treated with melamine-formaldehyde-boron combinations
1997 - IRG/WP 97-30135
Melamine formaldehyde (MF) resin was impregnated into scots pine (Pinus sylvestris L.) specimens with aqueous solutions of 5, 10 and 20% concs. Boric acid (BA) and borax (BX) was added to MF resin at the concentration levels of 0.25, 1.00 and 4.70% to each level of resin concs. BA and BX mixture was prepared at the 5:1 (w/w) ratio considering resultant pH of solutions and better fire resistance. U...

Environmentally benign wood preservatives based on organic biocide antioxidant combinations: A brief review of laboratory and field exposure results and discussion of a proposed mechanism
2004 - IRG/WP 04-30335
The combination of various organic biocides with commercial antioxidants generally increased the biocides’ efficacy 2-3 fold against wood-destroying fungi in short-term laboratory decay tests, and some positive results have been obtained after 2-4 years of outdoor exposure. The two antioxidants principally examined, propyl gallate and butylated hydroxytoluene, are low cost and, since both are f...

Protection of pile tops using combinations of internal treatments and water shedding caps
1993 - IRG/WP 93-30020
Preservative treatment produces an excellent barrier against fungal, insect, and marine borer attack; however, fabricators often disrupt this barrier during construction, creating avenues for entry of decay agents. This problem is particularly acute in marinas along the coastal United States. Standards recommend the application of a water-shedding cap at the time of installation to prevent pile to...

Wettability and bonding strength of wood thermally-treated with different combinations of soy oil and chemical additives
2009 - IRG/WP 09-40454
Thermal treatment is a method which has gained wider acceptability as an alternative to the chemical treatment in wood preservation. In order to maximize the benefits of this technique several options have been adopted including the use of soy oil in transferring the heat to the wood. Available information on thermal treatment in general and the oil method in particular show that there are still n...

The Concept of Copper and Boron Synergy: Why Copper Naphthenate and Borates are a Couple Made in Heaven
2013 - IRG/WP 13-30622
Fungicides are often combined for four basic reasons:(1) to widen the spectrum of the fungicidal activity in which to broaden the spectrum of activity, (2) to exploit additive and synergistic activities between actives, and the activities are increased and thereby reducing the needs for the higher loadings of the active in the substrate, (3) to delay the resistance of one of the actives in the for...
