Leaf samples collected from white clover plants in several eastern and southeastern states between 1986 and 1991 were tested for the presence of soybean dwarf virus (SbDV), bean leaf roll virus (BLRV), and beet western yellows virus (BWYV) by aphid transmission and serologyThe majority of the 991 samples were from randomly selected, asymptomatic, white clover plants in or near established clover stands.
