ABSTRACT
Devaluation of Canadian wood products by sapstain accounts for large and unpredictable losses each year. A large-scale survey of bluestain fungi in Canada found that the majority of aesthetic damage to softwood lumber was caused by three sapstain fungi: Ophiostoma piceae, O. pi1iferum, and O. floccosum. This paper reviews an evaluation of the tolerance of 30 of the isolated fungal strains (10 strains of each species) to a range of concentrations of active ingredients in different sapstain control products. The tolerance was correlated to the colony diameter after 12 days of fungal growth at 18[degrees]C on "pine-twig" agar amended with the chemicals at ...
