Abstract: | The combination of copper and N-methylol compounds considerably improves the performance against copper sensitive fungi (G. trabeum and T. versicolor), while the fungicidal effect against copper tolerant strain (A. vaillantii) remained insufficient. Addition of N-methylol compounds to copper solution significantly reduces leaching from wood blocks impregnated with the solution of the lowest copper concentration (cCu =0.1%), and less notably reduces leaching from wood blocks impregnated with solutions of higher copper contents (cCu=0.5%). |
