The objective of this work was to select isolates of Trichoderma spp. with potential of antagonism against Sclerotina sclerotiorum, in vitro. Twelve isolates of Trichoderma spp. and three isolates of S. sclerotiorum were used in the techniques "cling film - modified" and "direct confrontation". Based on the technique in vitro it the isolates TSM1, J10 and I1 of Trichoderma spp.were selected with better antagonistic activity, on the isolates of S. sclerotiorum.
