Resumo: | Charcoal Rot is a disease that occurs in a large number of plant species and besides not being economically controlled by fungicides no genetic resistance has been found. Associated with this controlling problem, there is also a growing awareness of the proper handling of pesticides or of the search for new and environmentally safer technologies for handling of plant diseases. Therefore this study aimed to examine in vitro the potential of different isolates of Trichoderma sp for biological control of Macrophomina phaseolina. Seventeen different isolates of Trichoderma sp. were used, in two different tests: direct confrontation with the pathogen and production of volatile compounds by the antagonist. In the experimental conditions the different isolates of Trichoderma sp. showed variation in the capacity of inhibition of the pathogen growth. Isolates TI1, TM2, TM3, TM4, TLB2, TLB3, TLB15 and TLB17 were those that showed the greatest antagonism to the fungus M. phaseolina.
