In Western Australia and southern Australia generally, subterranean clover mottle (SCMV) and bean yellow mosaic (BYMV) are the most damaging virus diseases of subterranean clover pastures.

Although infected plants cannot be cured of virus infection, pastures can be managed to reduce both virus spread and persistence from year to year. Management options depend on which virus is present and include reseeding with resistant varieties; changing the pasture composition so that non-host species predominate; altering grazing practices to limit spread; and application of pesticide sprays to kill aphids.
