PROBLEM TO BE SOLVED: To provide a microbial agrochemical composition having excellent stability of a microorganism, and hardly causing staining in field crops when sprayed, and to provide a method for producing the field crops with little staining including spraying the field crops with the microbial agrochemical composition.SOLUTION: There is provided the microbial agrochemical composition including 60-99 wt.% of calcium sulfate 1-40 wt.% of the microorganism having control effects on disease injury of plants and 0-30 wt.% of a surfactant, wherein the amounts are respectively based on the total amount of the calcium sulfate microorganism having the control effects on the disease injury of the plants and surfactant. Furthermore, there is provided the method for producing the field crops with the little staining including spraying the field crops with the microbial agrochemical composition containing the calcium sulfate and the microorganism having the control effects on the disease injury of the plants.COPYRIGHT: (C)2011,JPO&INPIT【課題】微生物の安定性に優れ、且つ散布した際に農作物に汚れが生じ難い微生物農薬組成物、および微生物農薬組成物を農作物に散布することを含む汚れの少ない農作物の生産方法を提供する。【解決手段】硫酸カルシウム、植物の病害を防除する効果を有する微生物、および界面活性剤の合計量に対して、硫酸カルシウム60~99重量%、植物の病害を防除する効果を有する微生物1~40重量%、および界面活性剤0~30重量%で含有する、微生物農薬組成物。硫酸カルシウムと植物の病害を防除する効果を有する微生物とを含有する微生物農薬組成物を農作物に散布することを含む、汚れの少ない農作物の生産方法。【選択図】なし
