DNA-based tools for rapidly detecting, quantifying and monitoring ophiostomatoid fungi on beetles, in trees and wood products
2010 - IRG/WP 10-20450
Approximately half of the trees harvested for commercial purposes are lost because of native or introduced insects or insect-vectored microorganisms. Ophiostomatoid fungi, which are well adapted to dissemination by insects, include ~140 species of saprobes and pathogens. They are present worldwide, have high economical impact and many are subject to quarantine regulation. Thus, it is necessary to ...

Morphological and Molecular Diagnosis of Leptographium spp. in Canadian Softwoods
2003 - IRG/WP 03-10479
Sapstaining fungi that affect commercially important softwood species mainly belong to the genera Ceratocystis, Ophiostoma and Leptographium. Our 1997-1999 fungal surveys confirmed that this is the case in Canada. The work reported here addresses identifying the morphologically plastic Leptographium at the species level, which is difficult using conventional methods. We assessed the morphologic...

Database of sapstain fungi affecting lumber, logs and trees
2004 - IRG/WP 04-10534
Sapstain fungi discolour lumber, logs and tree sapwood and are often mistaken for moulds, which cause a superficial discoloration. Stained wood has a lower market value. Further, because stained wood products can potentially carry pathogenic fungi, such products may be refused by importing countries. Addressing these issues involves developing ways for accurately identifying staining fungi, docume...
