Volatile metabolites produced by Bacillus subtilis and Bacillus amyloliquefaciens on the mycelial growth of Fusarium oxysporum f. sp. cubense

Abstract

Fusarium oxysporumf. sp. cubense is causing great losses to the banana culture. In view of
the inefficiency of the chemical control, the use of biological control has been an alternative
to your control. Thus, this work had the objective of an experience of the volatile metabolites
produced by Bacillus amyloliquefaciensand Bacillus subtilis on the mycelial growth of Fusarium
oxysporumf. sp. cubense. For the evaluation of volatile metabolites, the modified method
of Bharat et al. Petri dishes with BDA were positioned one above the other, being placed in the
bottom cover 4 drops of 50 μl in each quadrant of the commercial product ant top cover, a disc
of Fusarium. It was observed the effect of cell-free extracts of B. subtilis and B. amyloliquefaciensinhibiting
mycelial growth of Fusarium in the order of 49,44% and 50,33% respectively.
