Abstract
A bacterial inoculant for controlling root rot and damping off in corn, and for fostering the growth of corn, is disclosed. Also disclosed are two mutant bacterial strains, Burkholderia cepacia 2J6 and Burkholderia cepacia 2J6, which foster the growth of corn and protect against fungal disease.

1. A bacterial strain of Burkholderia cepacia which is derived from B. cepacia strain AMMD and which has the corn growth fostering characteristics of mutant strains 2J6 or 2358.
- 2. A bacterial strain of Burkholderia cepacia which has been derived from B. cepacia strain AMMD by a screening process in which there was a selection for mutants that did not produce a yellow-green pigment, and which strain has the ability to protect corn plants against a disease caused by a fungal species without causing chlorosis in corn plants.

8. An agriculturally useful composition comprising a corn seed inoculated with an inoculant of an essentially biologically pure culture of a bacterial strain selected from the group consisting of Burkholderia cepacia 2J6 (ATCC Accession No. 55982) and Burkholderia cepacia 2358 (ATCC Accession No. 55983).
- 9. A method for controlling a fungal pathogen in a corn plant comprising inoculating the plant with an effective amount of an essentially biologically pure culture of a bacterial strain having the characteristics of bacterial strains Burkholderia cepacia 2J6 (ATCC Accession No. 55982) and Burkholderia cepacia 2358 (ATCC Accession No. 55983), wherein said characteristics include the ability to protect plants against disease caused by a fungal species without causing chlorosis in plants.
