PROBLEM TO BE SOLVED: To provide a technique that is directly applicable to causal fungus of white root-rot inhabiting the outdoor environment, the technique enabling the desired mycovirus to arbitrary causal fungus of white root-rot irrespective of mycelium compatibility.SOLUTION: According to the present invention, there is provided a causal fungus of white root-rot having the following mycological properties (1) to (4): (1) the property that hyphae cultured on a PDA medium at 25°C has conidiogenic ability without forming any conidiophore bundle; (2) the property of cytoplasmic fusion to the mycelial cells of other causal fungus of white root-rot via conidia regardless of mycelium compatibility; (3) the property of allowing the retained mycovirus to be transferred to the mycelial cells of another causal fungus of white root-rot mycelium via the cytoplasmic fusion described in the above (2); and (4) the property of containing in genomic DNA a nucleotide sequence that shows 95% or more identity with a nucleotide sequence as a region between 18S rDNA and 28S rDNA or as a region included in such a region.SELECTED DRAWING: Figure 7
