PROBLEM TO BE SOLVED: To obtain a microbial agrochemical which imparts little load to the environment and can actively work even at a relatively low temperature in controlling phytophthora rot and downy mildew spreading even at a relatively low temperature in a terrestrial-part-disease control field wherein the appearance frequency of bacteria resistant to chemical agents is high; and to provide a control means which can contribute to IPM (integrated control). SOLUTION: The microbial agrochemical containing the biomass or culture product of Pseudomonas fluorescens bacteria is used for treating a terrestrial part of a plant; thereby, phytophthora rot and downy mildew can be easily controlled at a relatively low temperature. Since the agrochemical is of microorganisms separated from natural soil, the agrochemical and the method for controlling with it are friendly to the environment, and the means can contribute to IPM (integrated control).
