Abstract
Soilborne rhizosphere-incompetent biocontrol agents can be converted into rhizosphere-competent agents by exposing them to a mutagenic agent and then screening the exposed rhizosphere-incompetent agent for a strain showing increased cellulase production. The increased cellulase production characteristic serves to convert the originally rhizosphere-incompetent agent into one which is rhizosphere-competent. Seeds of plants to be protected against various diseases can then be treated with the rhizosphere-competent strain. The roots of the plant, as well as its original seed, are protected by biocontrol agents produced by the disclosed process.
