Improved PEC preservatives with added biocides
1985 - IRG/WP 3322
Biocidal chemicals have been incorporated into formulations within the broad framework of pigment emulsified creosote (PEC) to provide novel potential multi-purpose preservatives. Preparations of PEC plus TCMTB, Boracol 40, copper ethanolamine nonanoate, Quatramine 80, arsenic trioxide, Troysan Polyphase, and CCA have been formulated and assessed for preserving ability in soil-jar and Accelerated ...

Ammoniacal wood preservative for use in non-pressure treatment of spruce and aspen poplar. Part 1
1984 - IRG/WP 3273
End-matched lumber of Picea glauca (Moench)Voss (white spruce) and Populus tremuloides Michx. (aspen poplar) timbers was treated by a thermal diffusion process in open tank treating vessels using an ammoniacal copper-arsenate wood preservative. The process proved technically feasible with respect to controlling the vapourization of ammonia from open tanks during treatment at high temperatures. Tre...

The effect of Tween 80 on the growth, morphology, and enzyme secretion of Postia placenta
1990 - IRG/WP 1456
The nonionic surfactant Tween 80 (polyethylene oxide sorbitan mono-oleate) has been reported to increase enzyme production and/or secretion in bacteria and fungi. Such a procedure could greatly facilitate research into the physiology of wood-decay fungi since quantities of available enzyme are often limiting. The brown-rot fungus Postia placenta was grown in a synthetic medium supplemented with 0,...

A field evaluation of modified and unmodified alkylammonium compounds
1987 - IRG/WP 3436
Laboratory soil block studies of alkylammonium compounds (AAC's) at Forintek and other research establishments have shown that they can prevent decay by standard wood-destroying fungi. Their performance in field tests, however, has been disappointing. Following investigation of possible causes for this poor field performance, stakes treated with modified AAC's were installed at W...

Selección de hongos reductores de extraíbles del género Ophiostoma, mediante la prueba de opacidad Tween 80
2009 - IRG/WP 08-10677
Wood extractives cause diverse problems in the industry of the wood, the pulp and the paper; among others, they produce pitch deposition during the pulp manufacturing, generating important economic losses for the sector. Recently, to mitigate these effects, it has been proposed the biological pretreatment of chips and the solid wood with colorless fungi of different species from genus Ophiostoma. ...
