Description
Abstract Moulds, stain, and decay cause serious problems for wood utilization. Although a growing volume of wood is kiln-dried, the market for green exports remains significant, and environmentally 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, which was granted a U.S. patent. The method relies on an albino fungus, Gliocladium roseum, and a powder product has been formulated. Recently, a sawmill trial on this bioprotectant was carried out on 2,400 pieces of a mix of 2-inch by 3-inch by 8-foot black spruce and balsam fir boards. Mould, stain, and decay developments on treated and untreated boards were evaluated after 11 months of storage in a lumberyard. Results showed that 90 percent of boards treated with the powder product of this bioprotectant and 85 percent of those treated with the liquid culture did not get any fungal infection, whereas only 0.5 percent of untreated boards were clear. Concerning mould and stain growth, lumber treated with the powder product was 100 percent acceptable and lumber treated with the liquid culture was 99 percent acceptable, whereas untreated lumber was 16 percent acceptable. For decay evaluation, 45 percent of the untreated boards were, more or less, decayed after 11 months of storage in piles, whereas only 0.7 percent of powder product treated boards and 1.4 percent of liquid culture treated boards were affected by decay fungi.
