AB There is a growing interest in the development of sustainable alternatives to the use of chemical pesticides for pest management in agricultural systems. This research aimed to isolate and characterize native strains of Trichoderma spp. from different soils of Paraguay using morphological and molecular criteria. We processed plant and soil samples from eight commercial farms distributed in different departments of Paraguay and isolated 14 monosporic isolates of Trichoderma spp., obtaining two isolates from the Department of Alto Paraná (FCQ36 and FCQ37), four isolates from Cordillera (FCQ42, FCQ43, FCQ44, and FCQ46), one isolate from Central (FCQ32), and seven isolates from Itapúa (FCQ13, FCQ16, FCQ18, FCQ19, FCQ21, FCQ23, and FCQ47). In addition, phylogenetic analyses using the ITS and tef1α loci were carried out. A better resolution of the tef1a gene than the ITS region was observed. Moreover, a third phylogenetic tree from the concatenated ITS and tef1α sequences matrix was generated, obtaining the same topology with higher bootstrap support values. Through this approach, we reported for the first time the presence of Trichoderma koningiopsis (FCQ19, FCQ36, and FCQ37), Trichoderma neo¬koningii (FCQ13), and Trichoderma asperellum (FCQ42, FCQ43, FCQ44, and FCQ46), Trichoderma brevicompactum (FCQ18 and FCQ21), and Trichoderma longibrachiatum (FCQ 47) in Paraguay. The Trichoderma species identified in this study can be used to develop effective biocontrol products for agricultural and industrial purposes in Paraguay.
