(57) [Summary] (Modified) [PROBLEMS] To impart pest and disease resistance to grasses without using a chemically synthesized pesticide. That is, an organism utilizing a symbiotic fungus-introduced plant that artificially introduces a symbiotic bacterium comprising a bacterium capable of infecting and symbiotic with a plant and imparting resistance to a pest to a plant that has symbiotically infected with the plant. The present invention provides a chemical control method, a control agent and a seed to which the control agent is combined. SOLUTION: A symbiotic bacterium consisting of a bacterium that expresses pest and disease resistance is isolated from a naturally occurring plant, and the symbiotic bacterium is artificially cultured and introduced into a target gramineous plant, thereby obtaining the gramineous plant. Imparts pest and insect resistance. As the symbiotic bacterium, the genus Herbaspilillum, A Bacteria such as genus zospirillum are exemplified. Examples of the target pests include pests belonging to the order Lepidoptera, Orthoptera, Gross eyes, Coleoptera, or Hemiptera. |
