Agrocin 84 is an antibiotic produced by the nonpathogenic strain K84 of Rhizobium rhizogenes, its derivates, and other closely related bacteria. It inhibits the growth of many pathogenic agrobacteria, and strong evidence indicates that it is the major, but not the only, factor in the commercially successful biological control of crown gall. It has marked specificity and may be considered as the first nonprotein bacteriocin.
