Fungus cellar and field tests with tall oil derivatives. Final report after 11 years' testing
1993 - IRG/WP 93-30007
Two derivatives of tall oil were tested as wood preservatives in a fungus cellar and in ground contact (field test). Stakes of Pinus sylvestris sapwood were used in the tests. For the field test the size of the stakes was 20 x 50 x 500 mm³ and for the fungus cellar test 20 x 20 x 250 mm³. The stakes were vacuum-pressure treated with the two products and exposed in 1981. The field test site used ...

Colony elimination of Reticulitermes speratus (Kolbe) (Isoptera:Rhinotermitidae) by bait system
1997 - IRG/WP 97-10189
Following a two-year estimation of the foraging populations and territory of Reticulitermes speratus (Kolbe) by triple mark recapture program at Uji campus of Kyoto University, bait stations (commercialized products containing hexaflumuron) were set up in the foraging territory in October 1995 to eliminate the colony. Inspections demonstrated that the number of test stakes with foraging termites d...

SEM investigation of the production of extracellular mucilaginous material (ECM) by some wood inhabiting and wood decay fungi when grown in wood
1997 - IRG/WP 97-10193
Previous reports have illustrated the involvement of extracellular mucilage (ECM) in wood decay by Basidiomycetes. Its production is investigated in a range of stain, mould and soft rot fungi in Corsican pine, Scots pine and European beech. Fungi examined were: Chaetomium globosum, Ceratocystis coerulescens, Trichoderma harzianum, Ophiostoma piceae, Mucor sp. and Penicillium. sp. The samples were ...

Comparison between agar-block and soil-block methods for wood-destroying Basidiomycetes
1992 - IRG/WP 92-2401
The object of this work is to compare these methods in order to provide some information to help in the choice between them. The comparison was made by a statistical analysis (factorial completely randomized design) and by a discussion about other aspects of each method. An evaluation of some fungi on attacking wood and a comparison between Picnoporus sanguineus isolated from carpophore and decaye...

Kiln drying of CCA-treated wood - Some safety and environmental considerations
1987 - IRG/WP 3443
Vapours and condensate from a condenser kiln in which CCA-treated wood was being dried have been collected and analysed. The concentrations of arsenic, copper and chromium found in the vapours from the drying process were well below Swedish threshold limit values. The contents of arsenic and chromium were also low in the condensate, although the copper content was fairly high. The latter result wa...

Summaries of two Russian papers received from Professor Dr. D.A. Belenkov and V.A. Seletskaya of the Ural Forest Engineering Institute, Sibirsky Trakt, 37, Sverdlovsk, USSR, on the toxicity to Coniophora cerebella of salts of hydrofluoric acid and some fluoroborates
1977 - IRG/WP 298
1) Evaluation of the toxicity of some salts of hydrofluoric acid against the house cellar fungus (Coniophora cerebella Schroet) Data are presented on the method of probability evaluation of the toxicity of the fluorides of sodium, ammonium, potassium, zinc and iron. On the retention of fluorine in wood all salts, except iron, possess practically equal toxicity at the standard level of the probability of the protection of the wood - 0.95 . There is good agreement between the analytically and graphically determined dose level. Evidence is given for dose variabitility, probabilities of wood protection at 0.5 and 0.95, the curve of efficacy - activity and the construction of the empirical probit graph. 2) Investigation of the toxicity of some borofluorides towards the house cellar fungus Probability evaluation of the toxicity of borofluorides against the cellar fungus, and probit analysis evidence show that toxicity decreases in the sequence sodium borofluoride, copper borofluoride, tributyltin borofluoride. The effectiveness of protection method is able to evaluate the amount of fluorine and boron required in the wood.
