The cultivation of pecan tree [Carya illinoinensis (Wangenh.) K. Koch.] is expanding in Rio Grande do Sul state and, with that, there has been an increase the disease reports. Among diseases identified, a root rot caused by Fusarium spp. control phytopathogenic fungi present soil difficult to obtain, and through antagonists such as Trichoderma viable way management. Thus, objective this work was analyze different forms action asperellum antagonistic evaluated paring cultures, presence volatile non-volatile metabolites. mycelial growth inhibition culture pairing ranged from 10.38% 43.17%, while for metabolites protection lower, reaching values maximum 14.54%. As metabolites, percentage varied zero some treatments 44.99% graminearum. T. inhibited studied modes action.
