Some data on the activity of alternative fungicides for wood preservation
1985 - IRG/WP 3333
Data from laboratory tests against basidiomycete fungi are presented for 9 alternative fungicides in organic solvent formulations and also in water for one product. Results are compared with data for reference preservatives, tributyltin oxide, copper and zinc naphthenates and pentachlorophenol. Of special interest is the apparently better than additive effect of mixing tributyltin naphthenate and Xyligen B, and the promising performance of Armoblen 480, a novel organic solvent formulation of n-alkyl coco-derived quaternary ammonium compounds.

An evaluation of the potential of ion mobility spectrometry for detection of organic wood preservative components in solutions and treated wood
1994 - IRG/WP 94-20038
For the disposal of wood waste under ecological sound conditions information about its hazardous potential is required. Until now, no highly sensitive rapid analytical methods are available for the detection of wood preservatives under industrial process conditions. Preliminary experiments showed that Ion Mobility Spectrometry (IMS) could be a promising method for rapid detection of organic preservatives in waste wood. A number of organic wood preservatives (i.e. Al-HDO, Quat, Armoblen, Azaconzole, HCH, Creosote, DCFN, Furmecylox, MBT, Methyl-parathion, PCP, Permethrin, K-o-PP, TBTO, TCMTB and Tebuconazole) was studied. Both solutions and treated wood samples were analyzed with IMS. IMS-spectra are generated by analyzing the ionized volatile compounds of the samples. The time each ion needs to proceed to a detector is specific and can be characterized by a comparable Ko value, the so-called reduced mobility constant. A 'fingerprint' of the wood and the chemicals is obtained. IMS was able to distinguish between most of the preservatives. However, in wood, some of the chemicals could not be determined. So far the results are provisional and further investigation is needed.

Effects of wood-inhabiting marine fungi on food selection, feeding intensity and reproduction of Limnoria tripunctata Menzies (Crustacea, Isop.)
1981 - IRG/WP 480
The paper gives a condensed survey on laboratory tests with Limnoria tripunctata Menzies and pure cultures of 9 different marine wood-inhabiting fungi. Limnoria is able to distinguish between fungus-infested and non-infested wood. Wood with dead mycelium mostly proved to be less attractive or even repellent and was initially consumed less than with living fungi. On non-infested wood, initial feeding is retarded by 2 to 4 days. On fungus-infested wood less eggs degenerated and the number of reproductives was higher than on non-infested wood. Humicola alopallonella-infested wood yielded the highest number of reproductives. But the attractiveness of a fungus, the feeding stimulus produced by it and its nutritional value often did not correspond. It was not possible to make generally valid conclusions for one fungus species.
