1. In the present paper, certain resultant data of the laboratory experiments on evaluation of the fungicidal action of the certain commercial fungicides recently recommended for controlling the rice diseases in Japan against rice blast fungus are reported.
2. Fungitoxicity of the fungicides hitheto tested under the experimental condi-tion for controlling the rice blast fungus, is considered possibly due to the different-ces of durability and vapor action of them on the foliage.
3. It was proved in vitro that the organomercurials were distinctly efficacious than nonorganomercurials.
4. So far as the experimeits in vitro and in vivo were concerned, Mergon and Mei-ko-nung seemed could be determined as the practical fungicides. The efficacy of Mergon and Mei-ko-nung could cover that of the Fumiron recently recommended for controlling the rice blast in Taiwan.
本試驗為檢定Fumiron片劑，Takeda Mer片劑，simmer片劑，Mergon可濕性粉劑，Blaes M可濕性粉劑，Blaes S3可濕性粉劑，Dithane 31可濕性粉劑及Mei-ko-nung（美谷濃）乳劑等稱作病害常用之殺菌劑，對稻熱病菌之防治效力而舉行。於vitro，semi-vivo及vivo試驗中，由於實驗條件之不同，各藥劑之效果略有差異。但有機汞劑之效力均比非有機汞劑為佳，其中Mergo取可濕性粉劑及Mei-ko-nung （美谷濃）乳劑之防治與治療效果都比標準藥劑 Fumiron片劑較顯著。其藥效之高低，似與藥劑之持續效果及蒸氣壓之差異，具有密切關係。
