AVALIAÇÃO DO ANTAGONISMO DO FUNGO TRICHODERMA SPP. E SCLEROTINIA SCLEROTIORUM IN VITRO

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.
