| Summary: | Effective disease management is crucial for maintaining healthy turf. <i>Trichoderma</i> agents have emerged as a promising strategy for controlling turf diseases while reducing reliance on chemical fungicides. However, the distribution, diversity, and biocontrol potential of <i>Trichoderma</i> in turf ecosystems remain poorly understood. This study investigated <i>Trichoderma</i> strains isolated from rhizosphere soil of turf under different environmental and management conditions. Genetic distances were used to assess diversity, while co-culture assays evaluated inhibitory activity against <i>Rhizoctonia solani</i>. The Wilcoxon test was used for comparing diversity and antagonistic potential across environmental factors. The study identified <i>Trichoderma brevicompactum</i> and <i>Trichoderma harzianum</i> as the dominant species in turf ecosystems. <i>Trichoderma</i> diversity was highest in healthy turf under moderate management. However, strains from diseased turf showed stronger inhibitory effects on <i>Rhizoctonia solani</i>, suggesting that pathogen pressure and plant stress responses may enrich antagonistic <i>Trichoderma</i>. These findings provide valuable insights for the isolation and screening of <i>Trichoderma</i> species for effective biocontrol in turf management. |
