Pest control method for grass family plants using endophytic bacteria, pest control material, and seed bound to the pest control material
First Claim
1. A pest control material, which comprises endophytic bacteria isolated from a natural plant as its main ingredient, wherein the bacteria confer pest resistance to plants of Poaceae to which the bacteria are artificially introduced, wherein the conferred pest resistance is other than resistance to diseases caused by bacteria or filamentous fungi, wherein the endophytic bacteria belong to the genus Herbaspirillum or the genus Azospirillum.

Abstract
The objective of the present invention is to confer pest resistance to plants of Poaceae without using any chemically synthesized pesticides. The pest resistance can be conferred to plants of Poaceae by isolating from a natural plant an endophytic bacterium capable of expressing pest resistance, artificially culturing the endophytic bacterium, and introducing the bacteria to a Poaceae plant of interest.

3. A pest control material, which comprises endophytic bacteria isolated from a natural plant as its main ingredient, wherein the bacteria confer pest resistance to plants of Poaceae to which the bacteria are artificially introduced, wherein the conferred pest resistance is other than resistance to diseases caused by bacteria or filamentous fungi, wherein the endophytic bacteria have been dispersed in a binding agent that forms a seed-coating layer.

4. A pest control material, which comprises endophytic bacteria isolated from a natural plant as its main ingredient, wherein the bacteria confer resistance to plants of Poaceae to which the bacteria are artificially introduced, and wherein the endophytic bacteria belong to the genus Herbaspirillum or the genus Azospirillum, wherein the endophytic bacteria are one or more of the endophytic bacteria deposited in the National Institute of Advanced Industrial Science and Technology under the accession numbers FERM BP-10395, FERM BP-10447, FERM BP-7998, FERM BP-7999, and FERM BP-8000.
- 5. A pest control method for plants of Poaceae, which comprises infecting a plant of poaceae by artificially introducing endophytic bacteria into the plant, and thus conferring pest resistance to the plant via the endophytic bacteria, wherein the conferred pest resistance is other than resistance to diseases caused by bacteria or filamentous fungi, wherein the endophytic bacteria belong to the genus Herbaspirillum or the genus Azospirillum.

7. A pest control method for plants of Poaceae, which comprises infecting a plant of poaceae by artificially introducing endophytic bacteria into the plant, and thus conferring pest resistance to the plant via the endophytic bacteria, wherein the conferred pest resistance is other than resistance to diseases caused by bacteria or filamentous fungi, wherein the endophytic bacteria inhabit intercellular spaces in a plant, and express pest resistance in the plant.
- 8. A pest control method for plants of Poaceae, which comprises infecting a plant of Poaceae by artificially introducing endophytic bacteria into the plant, and thus conferring pest resistance to the plant via the endophytic bacteria, wherein the endophytic bacteria belong to the genus Herbaspirillum or the genus Azospirillum.
