Barley Yellow Dwarf Virus is vectored in Arkansas wheat by the bird cherry oat aphid. Although spring infections cause obvious yellowing of wheat fields in large patches, it is the stunting caused by fall infections that may be responsible for yield losses. Research was conducted to evaluate the feasibility of controlling the aphid vector as a way to reduce the incidence of BYDV in Arkansas wheat. Low disease incidence, low preditability of infection on an annual or field-by-field basis, and the large number of potentially viliferous aphid flights indicate that vector management is rarely if ever economically justified.
