PROBLEM TO BE SOLVED: To provide a solid bactericide composition having a bactericidal effect to fungi and general bacteria, and having a bactericidal effect also to microorganisms having resistivity to a quaternary ammonium salt and/or a biguanide-based bactericide, and hardly generating drug-resistant bacteria to itself.SOLUTION: A solid bactericide composition containing a compound represented by formula (I), a carbonate compound, and an organic acid having a solubility to water at 20°C of 0.25 to 35% is provided. In the formula (I), R1 is a saturated straight-chain alkyl group having 1 to 3 carbon atoms, R2 is a saturated straight-chain alkyl group having 8 to 12 carbon atoms, X- is a halogen ion, Y is a saturated straight-chain alkylene group having 8 to 12 carbon atoms.COPYRIGHT: (C)2014,JPO&INPIT【課題】真菌類および一般細菌に対して殺菌効果を有すると共に、第四級アンモニウム塩および/またはビグアナイド系殺菌剤に抵抗性を有する微生物に対しても殺菌効果を有し、かつ、それ自体に対する薬剤抵抗性菌が発生し難い固形殺菌剤組成物を提供すること。【解決手段】式(I)の化合物、炭酸化合物および20℃における水への溶解度が0.25~35%である有機酸を含有する固形殺菌剤組成物を提供する:(I)[式中、R1は炭素数1~3の飽和直鎖アルキル基、R2は炭素数8~12の飽和直鎖アルキル基、X-はハロゲンイオン、Yは炭素数8~12の飽和直鎖アルキレン基を表す]。【選択図】なし
