<i>Sclerotinia sclerotiorum</i> is a necrotrophic parasitic fungus that causes <i>Sclerotinia</i> stem rot (SSR), which is currently one of the most difficult agronomic crop diseases to control. A number of plants of the Brazilian Cerrado biome have been shown to be important sources of symbiotic microorganisms with biotechnological potential, so we decided to test the potential of bacteria isolated from the dwarf jelly palm, <i>Butia archeri</i> (Arecaceae) for the control of the pathogenic effects provoked by <i>S. sclerotiorum</i>.
