Sclerotium rolfsii caused potato losses of up to 20%, with the presence confirmed in 8.4% of fields.
Population densities of sclerotia ranged from 2 to 24 sclerotia kg-1 of soil; significant aggressiveness was noted in isolates.
Twenty isolates of Sclerotium rolfsii and twenty-six isolates of Trichoderma spp. were identified, highlighting diversity.
These findings suggest the need for integrated management strategies to control Sclerotium rolfsii, balancing pathogen variability and biological control.
