It was examined in the fungistatic power of several inorganic fluorine compounds, using Asp. niger, Clad. herbarum, Pull. pullulans, Al. tenuis?, Pen. cirinum as test molds. Also the fungistatic power of CuSiF_6 against spontaneous growth of molds at 30℃ and relative humidity of 95% was determined after 20 day's incubation.1) NaF, MgSiF_6・6H_2O, (NH_4)_2SiF_6,ZnSiF_6・6H_2O exerted no sufficient fungistatic effects on the growth of molds.2) When it was sprayed with conidial suspensions, the growth of molds on intact stems was inhibited by CuSiF_6 in a concentration of 5/1000 and that on the stems treated with boiling water by its concentration of 25/1000,and somewhat light brownish color was left to the substrata after drying.Spontaneous growth of molds was not observed on the stems treated with CuSiF_6 in a concentration of 25/1000 as in the case of direct inoculation of conidia on them.3) SbF_3NaF, SbF_3NH_4F showed almost no difference in the fungistatic effects on the growth of each mold, and inhibited it by a concentration of 5/1000 in case of direct inoculation of conidia, while a concentration of 15/1000 was necessary to inhibit the growth on stems sprayed with conidial suspensions after treating with boiling water.
