Two viruses, which showed the mosaic sympton, were isolated from Marguerite, Chrysanthemum frutescens L., in Chiba Prefecture in 1992. For the identification of these viruses, samples were examined by means of mechanical inoculation of crude sap into several test plants, electron microscopic observation of infected leaves using the dip method, and serological tests. One of isolates was identified as cucumber mosaic virus and the other as chrysanthemum virus B.
