Abstract: Provided are a novel cultivation method and a storage method that are suitable for storing bacteria belonging to the genus Collimonas for a long period of time. The cultivation method for bacteria belonging to the genus Collimonas is characterized in that bacteria belonging to the genus Collimonas are cultivated in a sealed state on a culture medium that includes a rice bran culture medium and/or a soy pulp culture medium. The storage method for bacteria belonging to the genus Collimonas is characterized in that the cultivated bacteria belonging to the genus Collimonas are stored at room temperature.

Abstract: The purpose of the present invention is: to produce a metabolite capable of improving drought tolerance of a plant to the same level as that achieved by abscisic acid, from a microorganism other than a microorganism that is known to be capable of producing abscisic acid; and to provide a method for improving drought tolerance of a plant using the metabolite. A method for producing a metabolite capable of improving drought tolerance using a microorganism, said method comprising culturing a microorganism that belongs to the genus Collimonas and has an ability of producing a metabolite capable of improving drought tolerance of a plant and then extracting the metabolite from a culture produced by the culturing.

Abstract: A method for producing a cell extract having agricultural pest insecticidal capacity by culturing filamentous fungi having insecticidal capacity for an agricultural pest, and a method for insecticide produced by this production method. A method for producing a cell extract having agricultural pest insecticidal capacity provided with a step for culturing filamentous fungi in solid medium and obtaining a solid culture of the filamentous fungi, a step for culturing the filamentous fungi in liquid medium and obtaining a liquid culture of the filamentous fungi, a step for separating mycelia of the filamentous fungi from the liquid culture of the filamentous fungi, a step for mixing the liquid culture from which the mycelia have been removed and the solid culture and obtaining a mixed culture, and a step for extracting a spore solution of the filamentous fungi from this mixed culture.

Abstract: Disclosed are: a seed having resistance to diseases; and a method for inoculating a microorganism into a seed for the purpose of controlling diseases. As a result of intensive studies, it is found that diseases of a crop can be controlled by inoculating a biofilm of a Bacillus bacterium into a seed of the crop. Specifically disclosed are; a seed inoculated with a biofilm of a Bacillus bacterium and a method for inoculating a biofilm of a Bacillus bacterium into a seed.
