Popis:	Mutants of Trichoderma sp. SKT-1 with tolerance to benomyl were easily induced with UV irradiation or nitrosoguanidine. Strain SKT-3 induced by UV irradiation possesses high tolerance to benomyl (MIC 1000μg/ml). Because it could be re-isolated on benomyl-containing culture media, activity of the strain could be tested in the environment, including soil and water systems. SKT-3 had suppressive activities against “Bakanae” disease and bacterial seedling blight comparable to its parent strain, SKT-1 and was compatible with benomyl-containing fungicides.
