Abstract
This study used pine wilt disease damaged trees as raw materials. The damaged woods were subjected to soaking treatment using wood vinegar, nematicide and sea water, fumigated treatment using fumigation, and the bending strength and hardness of the timber were measured at different points of time after the treatment. In soaking treatment, the highest bending strength was obtained from wood vinegar (100 fold dilution)-soaked specimens of Pinus densiflora and the nematicide-soaked specimens of Pinus thunbergii. The highest hardness in cross section was gained from the nematicide-soaked specimens of Pinus densiflora and Pinus thunbergii, the highest hardness in radial section was obtained from the nematicide-soaked specimens of Pinus densiflora and wood vinegar (100 fold dilution)-soaked specimens of Pinus thunbergii, and the highest hardness in tangential section was obtained from the nematicide-soaked specimens of Pinus densiflora and Pinus thunbergii, and there were not significantly different among the treatments. When fumigated treatment was applied, bending strength, hardness was somewhat lower in the control but were not significantly different between the treatments.
