We have discovered and introduced in culture in vitro hyperparasitic fungi: Tuberculinа persicina (Ditmar) Sacc. and Fusarium sambucinus Fuckel. In nature, these species caused a significant damage and antagonistic effect against the rust fungus Puccinia sp. on elderberry. The isolation and identification of regional hyperparasitic fungi are necessary to provide a pool of biological agents for biocontrol. The high activity of isolated isolates, as well as the possibility of obtaining spores on solid nutrient media, is promising for the biocontrol of rust fungi infecting wild and cultivated trees.
