Resumo: Yerba mate (Ilex paraguariensis) crop is susceptible to many disease-causing agents that affect a plant, like a root rot, reducing its productivity. The present study aimed to evaluate the in vitro antagonist potential of Trichoderma sp. on Fusarium oxysporum, the causal agent of root rot in yerba mate. Four Trichoderma spp. isolates and one Fusarium oxysporum isolate were used. The antagonistic action of Trichoderma spp. on F. oxysporum was evaluated through the dual cultures and volatile metabolites tests. The results of the dual cultures assay revealed that Trichoderma spp. inhibited the mycelial growth of Fusarium oxysporum, with percent inhibition ranging from 13.06 to 14.24%. Moreover, in the volatile metabolites test, T. tomentosum and T. harzianum showed the best inhibition results, 27.70 and 24.46%, respectively. Thus, Trichoderma spp. presented in vitro antagonist potential in the control of Fusarium oxysporum.

Dentre essas doenças têm-se a podridão-de-raízes causada por Fusarium spp. O objetivo deste trabalho foi avaliar a ação antagonista in vitro de Trichoderma spp. sobre Fusarium oxysporum, agente causal da podridão-de-raízes em erva-mate. Foram utilizados quatro isolados de Trichoderma spp. e um isolado de Fusarium oxysporum. A ação antagônica de Trichoderma spp. sobre F. oxysporum foi avaliada por meio do teste de pareamento de culturas e de metabólitos voláteis. No teste de pareamento de culturas, os isolados de Trichoderma spp. inibiram o crescimento micelial de Fusarium oxysporum, com percentual de inibição que variou de 13,06% a 14,24%. No teste de metabólitos voláteis, T. tomentosum e T. harzianum apresentaram os melhores resultados de inibição, com 27,70% e 24,46%, respectivamente. Assim, pode-se concluir que Trichoderma spp. apresenta ação antagonista in vitro contra F. oxysporum, agente causal da podridão-de-raízes em erva-mate.
