Problem: To provide a soil-transmissible plant disease control agent or similar that can safely be used as a biological control agent. Solution: A soil-transmissible plant disease control agent or similar, such as a vegetable bacterial wilt control agent, can be provided by using, as an active ingredient, live bacterial cells of a novel strain of a bacterium of the Bacillus or Fictibacillus genus with a heretofore unknown soil-transmissible plant disease controlling action, or a cultured product including said live bacterial cells. This control agent is characterized by being able, through a foliage application treatment, to control bacterial wilt and/or bacterial soft rot caused by the Ralstonia solanacearum species complex, which are soil-borne bacteria. Selected drawing: none [Problema] En la presente se proporciona un agente de control de enfermedades de plantas provenientes del suelo que se puede utilizar de forma segura como biopesticida, entre otros.            [Medios de solución] El componente activo utilizado en la presente invención incluye bacterias viables de nuevas cepas de Bacillus y Fictibacillus, o un cultivo de estas bacterias, que no se conocían por tener un efecto de control sobre las enfermedades de plantas provenientes del suelo. Esto permite proporcionar un agente de control de enfermedades de plantas provenientes del suelo, por ejemplo, un agente de control de marchitez vegetal. Una característica del agente de control es que se puede aplicar (pulverizar) sobre los tallos y las hojas para controlar una enfermedad de marchitez bacteriana causada por el complejo de especies de bacterias del suelo Ralstonia solanacearum, y/o la podredumbre blanda bacteriana.            [Dibujo seleccionado] Ninguno
