Abstract:
White mold is a disease of fundamental importance, being responsible for high
losses in agricultural production, and biological control is an alternative for its
control. The objective was to evaluate the antagonism and efficiency of volatile
metabolites produced by Trichoderma spp. to compete and inhibit the growth of
Sclerotinia sclerotiorum in vitro. For the evaluation of volatile metabolites, the
modified method of Bharat et al. Petri dishes with PDA were positioned one
above the other, with a mycelium disc of Trichoderma spp. placed on the center
plate. and in the upper and lower the pathogen. Therefore, the isolates were
confronted with the pathogen in a paired culture, and their metabolites were
evaluated on the pathogen's growth in the volatile metabolite assays. A great
antagonistic potential of Trichoderma spp. in paired culture and that the
metabolites produced are capable of inhibiting the growth of Sclerotinia
sclerotiorum in vitro.
