(57) [Summary] [PROBLEMS] To provide a high level of safety, have a bactericidal activity against pathogenic bacteria at a low concentration, and have a long-lasting bactericidal activity. It is an object of the present invention to provide a germicide that can be used repeatedly in a germicidal step without any decrease. SOLUTION: A fungicide derived from a natural product, comprising a polar solvent extract of eucalyptus plant leaves, chitosan and polylysine. It is effective that the weight ratio of the polar solvent extract of the leaves of Eucalyptus plant to chitosan is in the range of 1:10 to 10: 1, and that the total content of polylysine is 0.1 to 10 parts by weight based on 1 part by weight. Is high. |
