In order to prevent the mildew on bamboo stem, it was attemped to examine the fungistatic power of several organic mercurials against the growth of Asp. Miger, Clad. herbarum, Pull. pullulans, Alt. tenuis, Pen. citrinum and the spontaneous growth of molds at the temperature of 30℃ and relative humidity of 95% within 20 days. The effects of steeping in the ethyl mercuric phosphate solution were also studied.1) There was a difference in growth degree between the five species of molds on the stems treated wit organic mercurials, but phenyl mercuric dinaphthylmethane disulfonate, methoxyethylene mercuric chloride in a concentration of 25/1000000,and ethyl mercuric phosphate in a concentration of 1/100000 inhibited the growth of the molds on the stems either directly inoculated with conidia or sprayed with conidial suspensions.2) Spontaneous growth of molds was not observed on the stems treated with methoxyethylene mercuric chloride and ethyl mercuric phosphate in the same concentration as that in the case of direct inoculation with conidia and of spraying with conidial suspensions.3) When the stems were steeped in an ethyl mercuric phosphate solution, its volume varied not much with the number of steeping, but the content of the fungicide in a unit solution decreased with it. Therefore, it is necessary to regulate the available concentration of the fungicide in a solution with the number of times of steeping.
