An experiment with the fungal antagonists Phlebiopsis gigantea and Hypholoma fasciculare was conducted in 2006 in two protection forest stands of Norway spruce (Picea abies) in Eastern Tyrol. About 50% of the stumps showed stock-rot of Heterobasidion parviporum. Two isolated of Phlebiopsis gigantea (one from Poland and the product Rotstop) and one strain of Hypholoma fasciculare (from Poland) were applied on healthy stumps. In October 2006, all stumps were examined. The Phlebiopsis gigantea-strain from Poland had colonized 83% to 95% of the inoculated stumps, the Hypholoma fasciculare-strain 87% to 95%. The variant Rotstop resulted in only 10% to 13% colonized stumps. In more than 60% of the stumps colonized by Hypholoma fasciculare and Phlebiopsis gigantea (from Poland), large areas of the stump surface were covered by mycelium of the antagonist. In Rotstop only 40% showed intense colonization.
