Rice false smut caused by Villosiclava virens is a serious rice disease in Japan. To develop new method to control this disease, converter slag was tested to mix into paddy soil and additional application of simeconazole in 2015-2017. Converter slag was apparently suppressed the disease and additional simeconazole applications before heading enhanced the disease suppression. The result indicates that mixing of converter slag in paddy soil has some effects to soil-contained chlamydospores of this pathogen, and is a novel method to control this disease.
