Evaluation of a new anti-sapstain formulation
1994 - IRG/WP 94-30035
A new anti-sapstain mixture, which consists of 2% IPBC (3-iodo-2-propynylbutyl carbamate) and 1.5% DCOI (4,5-dichloro-2-n-octylisothiazolin-3-one), was evaluated by three methods in the laboratory. A standardized test (JWPA standard 2) demonstrated that the new anti-sapstain formulation was highly effective in controlling growth of monocultures of five test fungi on wood substrate. When exposed to...

Gaseous treatment of timber with allyl isothiocyanate. Fungicidal and insecticidal effects
1996 - IRG/WP 96-30108
Gaseous treatment with allyl isothiocyanate (AIT) was tested for its effects on the growth of microorganisms on the wood substrate and the mortality of subterranean termites and powder-post beetles. Toxic limits of AIT were determined as concentrations in the air when an AIT-treated filter paper was placed in a sealed container with fungus-inoculated wood specimens. Those were <3.8 ppm for Aure...

Antagonistic properties of Gliocladium virens against wood attacking fungi
1996 - IRG/WP 96-10162
Gliocladium virens has shown good antagonism against decay fungi in agar medium and in wood blocks. Gliotoxin produced by Gliocladium virens is associated with biocontrol of some plant diseases, but its importance to biocontrol of wood-attacking fungi is unknown. We investigated the ability of gliotoxin-producing (GLT+) isolates of Gliocladium virens and gliotoxin-deficient (GLT-) mutants of Glioc...

Antagonism of Gliocladium virens against wood decay fungi
1995 - IRG/WP 95-10102
Antagonistic abilities of a commercial biofungicide, Gliocladium virens (GL-21, Grace) were evaluated against three white-rot fungi, Trametes versicolor, Phlebia brevispora, Irpex lacteus, and three brown-rot fungi, Postia placenta, Neolentinus lepideus, Gloeophyllum trabeum. In dual culture of Gliocladium virens and wood decay fungi, Gliocladium virens rapidly overgrow the decay fungi and killed ...

Proposed degradation pathway for quaternary ammonium compounds by mould fungi
1996 - IRG/WP 96-10166
One group of chemicals that has attracted considerable attention as potential wood preservatives are the quaternary ammonium compounds (QACs). Based upon results of previous research this study confirmed the degradation pathway employed in QAC-tolerant fungi. For this experiment the two dialkylammonium compounds didecyldimethylammonnium chloride and dioctyldimethylammonium chloride were used. QAC-...

The use of chlorothalonil for protection against mold and sapstain fungi. Part 1: Laboratory evaluation
1989 - IRG/WP 3515
Laboratory screening of chlorothalonil alone and in combination with other fungicides was conducted against six mold and sapstain fungi. The most promising treatments appear to be chlorothalonil supplemented with CCA or copper-8-quinolinolate. Field tests have been implemented....

The effect of didecyldimethylammonium chloride on growth of different strains of mould fungus Gliocladium roseum
1995 - IRG/WP 95-10105
The tolerance and degrading ability of different strains of Gliocladium roseum towards didecyldimethylammonium chloride (DDAC) were studied. All four of the strains of Gliocladium roseum were tolerant to DDAC and after their growth on amended malt agar, the retention of DDAC in the medium was reduced....

Bioremediation of surfactant contaminated waste
1996 - IRG/WP 96-50070
The objective of this work was to determine the potential of fungi as agents for the bioremediation of wastes (particularly wood and soil) contaminated with quaternary ammonium compounds (QACs). Until now only bacteria have been investigated for this purpose. Tolerant strains of Gliocladium roseum and Verticillium bulbillosum were studied for their ability to degrade the following QACs: didecyldim...

Sawmill Evaluation of a Bioprotectant against Moulds, Stain and Decay on Green Lumber
2003 - IRG/WP 03-10460
Moulds, stain and decay cause serious problems on wood utilization. Though a growing volume of wood is kiln-dried, the market for green exports remains significant, and environment-friendly wood protection is required to replace traditional chemicals. As a solution to this problem, Forintek Canada Corp. developed a bioprotectant for protecting logs and green lumber from moulds, stain and decay, wh...
