summary(En) :	Plywood samples were prepared in glues into which 1 of 7 kinds of fungicides was incorporated. A threshold amount of preservative based on dry wood weight was used to prevent decay (Table 1). Bond quality was tested on wet and dry samples (Table 2). The efficiencies of wood preservation evaluated by the following three methods are as follows:    1) Percentage weight loss in decay test    Na-PCP, Na-DNOC, NCH-K, NaF and TBTO incorporation made plywood resistant to Tyromyces palustris and NaF was the most effectiveness of 7 fungicides against Coriolus versicolor (Table 3).    2) Area of wood surface covered by mycelia    NCH-K and TBTO incorporation made plywood resistant to T. palustris but only NaF was effective against C. versicolor (Figure 1).    3) Change of residual ratio of compression strength during decay test    NCH-K, NaF and TBTO incorporation made plywood resistant to T. palustris but no fungicides were effective against C. versicolor (Table 3).    As a result of the above evaluations, NaF was recommended to be incorporated in urea-melamine glue for preservation of plywood.
