Trichoderma isolate TCAS significantly reduced S. rolfsii disease incidence in stevia compared to control treatments.
The area under the disease progress curve (AUDPC) for TCAS was 7.67, markedly lower than other treatments like commercial T. viride.
This observational analysis tested ten native Trichoderma isolates from Paraguayan soils for effectiveness against S. rolfsii.
Results highlight TCAS's potential for managing diseases in organic and conventional stevia production, indicating practical applications.
