ABSTRACT:
The invention includes substantially pure cultures of ATCC 53522 and mutants thereof effective in protecting plants from damping off the root rot as determinable by a defined plant protection assay. The invention further includes a protecting toxin produced by the bacteria just referred to. A seed inoculum includes an effective quantity of the bacteria or the toxin in a carrier. A method for protecting plants from damping off and root rot includes placing an effective quantity of the bacteria or toxin in the immediate vicinity of a plant to be protected.
