Supressão da murcha de fusário em tomateiro por rizobactérias do gênero Bacillus1

Abstract: RESUMOMurchas vasculares em tomateiro constituem importante grupo de doenças incitadas por patógenos habitantes de solos, com destaque para Fusarium oxysporumf. sp. lycopersici, que ocasiona perdas significativas de produção. A introgressão de genes que expressam resistência é a principal medida de controle, mas, devido à rápida emergência de raças que suplantam a resistência, vem aumentando a importância do biocontrole, em integração com o controle genético. Objetivou-se avaliar a capacidade de isolados de ri… Show more

“…In this test, the experiment was installed in a completely randomized design, with ten replications and two plants per plot. The treatments consisted of T1: seeds treated with B. japonicum; T2: microbiolized seeds by soaking, for one hour, in a suspension of propagules of A. brasilense (Carrer Filho et al, 2015); T3: microbiolized seeds by A. brasilense and treated with B. japonicum; and T4: seeds immersed in sterile saline solution without bacteria. BRS-1051 corn seeds were treated with propagules of each bacteria and sown in 4.5 L pots containing autoclaved Bioflora ® substrate, containing pine bark, vermiculite, and coconut fiber.…”

“…Endophytic microorganisms can produce toxins, antibiotics and secondary metabolites such as iturins, that act by inhibiting the germination of phytopathogens (Chen et al 2018) and surfactin, that forms biofilms and prevents the host's recognition by the phytopathogen (Carrer Filho et al 2015). Endophytic bacteria are also effective producers of volatile, liposoluble compounds and therefore have high solubility in fungal membranes (Fadiji & Babalola 2020).…”
