Effect of a microbial inoculum (Material A) which contains 5 strains of antagonistic Actinomycetes against Fusarium oxysporum with an organic carrier on the control of Fusarium diseases was investigated in pot, frame plot and field experiments. Material A suppressed radish yellows in pot and frame experiments using infected field soils and affected the population density of F. oxysporum in radish roots and rhizosphere soils. In the field experiments, radish yellows and Fusarium wilt of strawberry were also suppressed by the application of Material A. The suppressive effect of Material A on Fusarium diseases was more pronounced in stripe application than in broadcasting application. Co-application with chlorpicrine was the most effective way of using Material A for the control of Fusarium diseases. The control effect of Material A on Fusarium diseases was influenced by the application of a large amount of other organic materials, such as bark compost, cow compost or pig compost. In many cases, Material A was effective in the control of Fusarium diseases such as radish yellows and Fusarium wilt of strawberry. Control of the diseases using this material may be successful when it is combined with the application of other chemicals.
