ISOLATION OF TRICHODERMA SPP. IN RURAL AREAS OF FIVE DISTRICTS IN ITAPUA, PARAGUAY

Fungal species of the Trichoderma genus are widely recognized for their effectiveness as biological control agents against phytopathogenic fungi of significant agricultural importance. However, Paraguay lacks commercially available products based on native isolates. In this context, the present study focused on obtaining native Trichoderma spp. strains from the districts of Trinidad, Mayor Julio Dionisio Otano, Fram, Carmen del Parana, and Natalio, in the Itapua region. The results suggest the possible presence of Trichoderma spp. in all five analyzed districts, as the isolated samples initially exhibited a greenish-white coloration, which later evolved into an olive-green hue, a macroscopic characteristic distinctive of this fungus. Further identification and characterization of native Trichoderma spp. strains will not only enhance disease control efficiency but also reduce dependence on agrochemicals.
