In order to prevent the mildew on bamboo-stems, it was attempted to examine the fungistatic power of Na-dehydroacetate and Na-sorbate.1) Na-dehydroacetate solutions in several concentrations were permeable to a unit area of bamboo tissues in almost the same degree, and more readily in cross sections than in tangential sections.2) Na-dehydroacetate solutions of pH 3.0〜3.8 and Na-sorbate solutions of pH 3.0 showed a strong fungistatic power.3) At 30℃, and relative humidity of 95% and for 24 days.Of the test molds, Asp. niger and Pcn. citrinum were inhibited in their growth by a concentraiton of 2/1000 of Na-dehydroacetate but not by the same concentration of Na-sorbate. A concentration of 1/100 of Na-dehydroacetate inhibited the growth of the molds on stems sprayed with conidial suspensions.4) At the room temperature for 24 days. (rainy season).The growth of mods under natural conditions was not observed on the stems treated with Na-dehydroacetate in the same concentration as that in case of direct inoculation of conidia.
