It is found in various countries worldwide and can grow in a variety of habitats.  Trichothecium roseumA variety of secondary metabolites including mycotoxins, such as rosinotoxins and trichothecenes, which can be described as a variety of fruit crops.  It can be used as a pathogenic and opportunistic pathogen in the field of various diseases and their impact on the farming industry.  Secondary metabolites of T. roseum , specifically Trichothecinol A, are being investigated as potential anti-metastatic drugs. Several agents including harpin, silicon oxide, and sodium silicate are potential inhibitors of T. roseum growth on fruit crops.
