The effect of copper on the growth of wood-rotting fungi and a blue-stain fungus
World Journal of Microbiology and Biotechnology, 2007The effect of copper (II) ions on the growth of three brown-rot fungi, six white-rot fungi and one blue-stain fungus in solid medium was evaluated. The fungi were grown in malt extract agar with different concentrations of copper added, and the radial growth rate was determined. At the end of the incubation period, the mycelial biomass and the media pH

Progress in Organic Coatings, 2023 The susceptibility of surface-modified wood, surface-modified acetylated wood and acetylated wood to mold and blue stain fungi was investigated. The surface modifications were based on fluorinated and non-fluorinated silicone nanofilaments for increased hydrophobicity. Results showed an increased mold resistance of the surface-modified superhydrophobic

Comparative virulence of blue-stain fungi isolated from Japanese red pine
Journal of Forest Research, 2003We made inoculations to determine the comparative virulence of blue-stain fungi isolated from Japanese red pine (Pinus densiflora Sieb. & Zucc.). Based on the symptoms caused by each fungus, the most virulent fungus was Leptographium wingfieldii. Also, Ophiostoma minus was relatively virulent while lesions induced by some species did not differ from ...

Inhibition of growth of blue stain fungi by wood extractives
Canadian Journal of Botany, 1968Resistance by lodgepole pine to invasion by blue stain fungi is effected by an initial flow of oleoresin followed by a gradual impregnation with resinous substances of the tissues adjacent to the wound. The addition of such resinous sapwood to growth media caused inhibition of growth whereas non-resinous sapwood enhanced growth; however, extracts from

Biological Control of Blue-Stain Fungi in Wood
Phytopathology, 1995Biological control of blue-stain fungi, such as Ophiostoma spp., that are detrimental to the wood products industry, was demonstrated in laboratory and field trials by a colorless strain of O. piliferum. Cartapip-97. This strain lacks melaninlike compounds responsible for the discoloration of sapwood. Inoculation of logs with Cartapip in the laboratory

Secondary Metabolites and the Control of Some Blue Stain and Decay Fungi
1999Wood discoloration has been grouped in four categories based on the cause of the stain: enzymatic and chemical reactions, changes caused by contact with chemicals, chemical reactions acompanying the early stages of decay, and color changes associated with the growth of fungi (1).Only the latter two types of discoloration (biotic stains) will be ...

Susceptibility of thermo-hydro-treated birch plywood to mould and blue stain fungi
Wood Material Science & Engineering, 2017ABSTRACTIn this study, mould and blue stain susceptibility, capillary water uptake (CWU) and microstructural properties of two thermo-hydro-treated (THT) birch plywood products A and B were investigated. Plywood A represented a THT industrial plywood glued with a phenol formaldehyde (PF) adhesive.

REACTIONS OF LODGEPOLE PINE TO ATTACK BY DENDROCTONUS PONDEROSAE HOPKINS AND BLUE STAIN FUNGI
Canadian Journal of Botany, 1967The reaction in lodgepole pine in response to attack by Dendroctonus ponderosae and subsequent infection by blue stain fungi varies with the degree of resistance manifested by the tree. In both resistant and successfully attacked trees a sequence of changes, which increase in space with time, occurs in the inner bark and sapwood.

Transmission of Blue-Stain Fungi by Ips typographus (Coleoptera: Scolytidae) in Norway Spruce
Annals of the Entomological Society of America, 1990Spores characteristic of the tree pathogenic blue-stain fungus, Ophiostoma polonicum Siemasko, and other fungi are visible in scanning electron micrographs of pits on the pronotum and elytra of Ips typographus (L.). Inoculation and reisolation experiments show that O. polonicum was transmitted to logs at generally higher frequencies by live beetles and
