Resumo

The common bean (Phaseolus vulgaris) constitutes a very important crop in the feeding of the Brazilian population. The curtobacterium wilt or bacterial wilt, caused by Curtobacterium flaccumfaciens pv. flaccumfaciens (Cff), is a vascular disease that affects the common bean, leading to significant damage. In this context, the aim of this study was to evaluate the in vitro effect of Bacillus spp. on the inhibition of two Cff isolates, the colonization of the root system and the development of common bean seedlings. Two in vitro assays were performed to verify the antagonistic activity of the isolates Bacillus licheniformis, B. subtilis, and B. subtilis + B. lichenformis against two isolates of Cff. All isolates of Bacillus spp. inhibited the growth of Cff isolates. Common bean seedlings showed no root colonization by the evaluated bacterial isolates.
