Eradication of wood decay fungi by means of radio frequency
1998 - IRG/WP 98-10292
High frequency electromagnetic fields i.e. radio frequency (RF) are used in wood industry for heating, gluing and bending of wood and are also appropriate for eradicating of wood decay fungi and insects. We investigated the effects of RF exposure on wood samples which were in vitro infected by Coniophora puteana, Gloeophyllum trabeum and Lentinus lepideus. For each fungus, the lethal temperature a...

Biological control of internal decay in Scots pine poles: A seven year experiment
1992 - IRG/WP 92-1529
The interactions between key fungi were monitored, by non-destructive and destructive sampling methods, during the course of an experiment on the effectiveness of Scytalidium sp. and Trichoderma spp. for eliminating established infections of Lentinus lepideus (Fr. ex Fr.) Fr. in creosoted Pinus sylvestris poles. Although extensively isolated at the beginning and end of the experiment, Trichoderma ...

Selecting fumigants for treatment of internal decay in wood
1986 - IRG/WP 3370
A number of potential fumigants were screened with respect to their toxicity to decay fungi, (Poria carbonica, and Lentinus lepideus) and their sorption characteristics on Douglas Fir (Pseudotsuga menziesii Mirb. Franco) wood. Wafers of infected wood were exposed to different fumigant concentrations for various times then cultured to determine viability. The lethal concentration X time (ct) factor...

The resistance of wood coated with different water-borne paints against colonisation by decay fungi
1996 - IRG/WP 96-10165
The susceptibility of wood painted with model paints of known composition to decay fungi was tested without previous weathering. Included in the study were five alkyd emulsion paints and five acrylic paints; one linseed oil paint and two solvent-borne alkyd paints. It was found that several components influenced the susceptibility of these paints. The results of the present study indicate that the...

A field evaluation of chromated fluoride as a remedial treatment for creosoted wooden distribution poles
1989 - IRG/WP 3556
A commercial chromated fluoride formulation was applied by injection process to previously inoculated creosoted wooden distribution pole sections at a field site in Scotland and appraisal of the efficacy of the formulation against Lentinus lepideus was undertaken at two month and fifteen month intervals. Preliminary results suggest a rapid elimination of organisms from colonised areas. The usage o...
