Abstract
Abstract The invention includes a substantially pure preparation of Bacillus cereus antibiotic. The invention further includes a seed inoculum for application to seeds to be protected from damping off and root rot including a non-interfering carrier and an effective quantity of Bacillus cereus antibiotic, and a method for protecting plants in a growing medium from damping off and root rot including the step of placing in the growing medium in the immediate vicinity of the plant to be protected an effective quantity of Bacillus cereus antibiotic.
