Laboratory Evaluation and Field Trial of Chlorothalonil and Copper-based Preservatives and Leaching Performance of Copper in Copper Treated Wood
2002 - IRG/WP 02-30279
Soil block test and field trial of some Chinese plantation wood species pine and poplar treated with chlorothalonil formulations and copper-based preservatives such as ACQ-B and copper citrate (CC) were conducted. The results of soil block test indicated that chlorothalonil formulations and ACQ-B as well as CC are very effective for controlling the 2 fungi species Corious versicolor and Poria plac...

Copper Migration from Micronized Copper Preservatives Treated Wood in soil contact:
2011 - IRG/WP 11-50280
Emerging formulations of preservatives made with micronized basic copper carbonates with azoles and/or quat to control copper tolerant fungi have been used to replace formulations containing soluble copper to reduce the leaching of copper and the corrosion of metal in contact with wood. This study proposes to use laboratory soil leaching test AWPA standard (E20-08) to estimate the amount of copper...

Identification of Antifungal Compounds in Konjac Flying Powder and Assessment against Wood Decay Fungi
2019 - IRG/WP 19-30737
The antifungal activity of konjac (Amorphophallus rivieri) flying powder (a by-product produced during mechanical processing of konjac flour) ethanol extract was evaluated against wood decay fungi in culture. Compounds associated with antifungal activity in the extracts were isolated and purified by silica gel column chromatography. The antifungal active fractions were identified by ultra-high-per...
