Antagonistic effect of some mycorrhiza fungi as biological control of blue-stain
1987 - IRG/WP 1314
This report discussed the possibility of using some mycorrhiza fungi as biological control of blue-stain. The results show that new bio-technological possibilities are opening, because, by cultivating antibiosis fungi in fermentor, it is possible to prepare extracts which can then be used as the natural preservative to control the blue-stain in wood....

Biological control of blue stain on wood with Pseudomonas cepacia 6253. Laboratory and field test
1989 - IRG/WP 1380
Pseudomonas cepacia strain 6253 was tested as a biological control agent on wood samples under laboratory conditions, as well as in the field. In the laboratory this bacterium controlled blue stain on Pinus radiata, but field test were not totally satisfactory. However, after 2 months of field test, the test samples were 1/3 to 1/2 less stained then the control samples....

Bacteria as possible organisms for biological control of blue stain
1988 - IRG/WP 1339
The article discusses the possibilities of biological control of blue stain. Besides using some antagonistic fungi, the possibility of using antagonistic bacteria, which offer still greater possibilities, should not be overlooked. Tests performed have shown that some bacteria from the genera Streptomyces and Pseudomonas have a strong antagonistic effect of blue stain....

Preservation of robinia wood (Robinia pseudoacacia L.) stakes by vintners
1982 - IRG/WP 3194
This work discusses decay resistance of robinia wood to fungi Trametes versicolor (L.ex Fr.) Pil. and Coniophora puteana (Schum. ex Fr.) Karst., and also the possibility of influencing its resistance by means of chemical protection. The results showed that natural resistance of robinia wood to these two different agents of wood decay is not the same. It is much less resistant to the fungus Conioph...

Wood colonizing fungi as a human pathogen
1992 - IRG/WP 92-1523
Today we recognize some 174 "pathogens" among the approximately 100000 species of fungi, which cause different diseases on man. 24 fungi which are well known as wood colonizing fungi have been identified as opportunistic human pathogen. Some of them have been found on the surface of the human body, causing superficial mycoses, or cutaneous infection, like dermatophytosis or dermatomycosis. Other c...

Evaluation of bacteria for biological control of wood decay
1990 - IRG/WP 1426
Laboratory soil-block and agar-block tests were carried out to evaluate the efficacy of bacteria as biological control agents against 5 brown-rot and 3 white-rot fungi. Pretreatment of Southern pine and sweetgum with a bacterial solution prevented decay in agar-block tests. However, the bacteria were generally ineffective in preventing decay in Southern pine, Douglas-fir, sweetgum and yellow popla...

Laboratory studies on control of sapstain and mold on unseasoned wood by bacteria
1991 - IRG/WP 1493
A malt-agar and nonagar laboratory test was used to evaluate the efficacy of bacterial preparations as biological control agents against several sapwood-inhabiting fungi. Both nonsterilized and filter sterilized bacteria preparations prevented attack by the sapwood-inhabiting fungi. Streptomyces rimosus was the most effective bacteria, giving good protection, with a 1-hr soak in a filter-sterilize...

Wood injurers found at wood processing plants in SR Sloveni
1981 - IRG/WP 1140
This report describes the stating of damages on wood and taking stock of wood injurers found in the warehouses of wood processing plants in SR Slovenia. The results of this research show that in the process of manufacture vast quantities of spruce-wood, pine-wood, beech wood, oak-wood, and poplar-wood are exposed to numerous injurers, both fungi and insects. The reasons for such a state lie in con...

The study of blue stain found in coniferous timber in SR Slovenia (Yugoslavia)
1983 - IRG/WP 1177
The report concerns the problems connected with blue stain in coniferous timbers stored in warehouses at wood-processing plants in SR Slovenia (Yugoslavia). The amounts of spruce-wood (Picea abies Karst.) found to have been infected with blue stain have been measured and some of the fungi causing the stain have been identified and their biology studied. It was found that the percentage of spruce-w...

Mycoparasitism by some white rot fungi on blue stain fungi in culture
1986 - IRG/WP 1304
When studying biological control of blue stain an interesting phenomenon of parasitism by some white rot fungi on blue stain fungi has been encountered. The majority of the 22 tested white rot fungi act parasitically upon blue stain fungi. The most interesting species among them is Bjerkandera adusta (Willd. ex Fr.) Karst., causing almost complete or complete decoloration of the hyphae of the blue...
